The second watch features an exquisite tourbillon. The third watch takes its design cues from the 1928 prototype, complete with a pulsometer scale gracing the dial periphery. Single push-piece chronographs are among the most coveted complication timepieces and demand exceptionally complex production techniques, while Vacheron Constantin has also unveiled a ladies' double push-piece chronograph. Furthermore, three dual-time watches powered by Vacheron Constantin's proprietary movements complete this extraordinary collection. Like all recent creations from the Maison, these special editions bear the prestigious Geneva Seal.

 

       Founded in Geneva in 1755 by the young watchmaker Jean-Marc Vacheron, Vacheron Constantin is the world's oldest watch manufacturer in continuous production since its inception. To celebrate its 260th anniversary, Vacheron Constantin presents the inaugural exclusive models of a brand-new collection. Entitled “Harmony”, the new line draws inspiration from the distinctive, structurally defined chronographs created by Vacheron Constantin in the late 20s20, adopting a fresh cushion-shaped profile imbued with contemporary flair that highlights the manufacture's exceptional watchmaking prowess. The tiered case architecture creates a perfectly balanced three-dimensional aesthetic, once again demonstrating Vacheron Constantin's expertise as a “ watchmaking sculptor”. To ensure precision, readability and wearing comfort, the case features a refined and clean design. Moreover, this striking new cushion-shaped case design contrasts sharply with the signature round and tonneau-shaped cases found in Vacheron Constantin's existing classic collections.

A refreshed cushion-shaped exterior

       The seven timepieces debuting the Harmony collection are this year's limited anniversary editions, featuring chronograph and dual-time functions, powered by four movements newly developed and manufactured in-house by Vacheron Constantin, alongside one variant refined from an existing proprietary chronograph calibre. Conceived as sculptural works of art, this collection aims to blend multiple in-house innovations with thoroughly modern appeal. The cushion-shaped case lines are generous and elegant, housing medium and grand complication movements.

       Demonstrating its fine watchmaking expertise once again, Vacheron Constantin unites aesthetic lines with horology by introducing a cushion-shaped case construction reminiscent of a design from the brand's nearly century-old heritage. The curved case, square-round bezel and round crystal combine to elegantly recreate the single push-piece chronograph featuring a pulsometer scale created by Vacheron Constantin in 1928. Although inspired by historical classics, every single detail has been re-imagined and refined, right down to the angles at which the case reflects light, ensuring optimal wearing comfort while presenting an unprecedented, distinctive silhouette. Similarly, every detail of the dial and hands has been refined from the 1928 prototype to guarantee optimal legibility of all indications.

The much-anticipated chronograph

 

       The Harmony collection is equipped with movements entirely developed and manufactured by Vacheron Constantin, combining several major watchmaking technical and aesthetic innovations. The anniversary models of this new collection are the precursors to a completely new line introduced by Vacheron Constantin in 2016. Vacheron Constantin began offering complications in 1917, and chronographs have always held a prominent place among them. The monopusher chronographs of the Harmony collection are refined and elegant, embodying the infinite patience, superb skill, and rich experience of the watchmakers, making them highly favoured by haute horlogerie connoisseurs. Four of the watches introduced in the new Harmony collection showcase Vacheron Constantin's outstanding short-time measurement functions: the first is equipped with the Calibre 3500, which is only 5.20 mm thick, making it the world's thinnest self-winding monopusher split-seconds chronograph movement; the second is powered by the Calibre 3200 manual-winding monopusher chronograph movement with a tourbillon; the third, inspired by a historical antique timepiece from 1928, is powered by the Calibre 3300 manual-winding movement and is a monopusher chronograph with a pulsometer scale; the fourth is a ladies' dual-pusher chronograph powered by the Calibre 1142 manual-winding movement.

Newly developed in-house movement

       After seven years of research and development, three new monopusher chronographs in the Harmony collection are equipped with movements entirely developed and manufactured by Vacheron Constantin, upholding the brand's watchmaking heritage while utilising cutting-edge watchmaking technology. The movement architecture features a classic column-wheel construction, reflecting the traditional aesthetic philosophy of Vacheron Constantin haute horlogerie. The design of these new movements benefits from modern manufacturing processes, significantly improving materials, precision, functionality, aesthetics, and operational performance. Similarly, the Calibre 2460 DT self-winding complicated movement, developed in-house by Vacheron Constantin in 2008, features a dual-time display, also demonstrating the perfect fusion of traditional craftsmanship and advanced technology. This movement is housed in two elegant men's watches in white gold and pink gold respectively, as well as a diamond-set ladies' watch in white gold, allowing all functions of the watch to be operated via the crown thanks to the ingenious movement mechanism.

       Today, Vacheron Constantin perfectly blends watchmaking excellence with a unique aesthetic pursuit, developing various new movements equipped with complications, dedicated to mastering different time-measurement technologies:

 Time measurement and sequential time measurement: chronograph and split-seconds chronograph functions •   One-touch operation: monopusher •  Precision timekeeper: tourbillon device •  Heart rate calculation: pulsometer scale •  Different time displays: dual time

       Like other Vacheron Constantin in-house movements, these new manufacture movements uphold the traditions of haute horlogerie, with their intricate and diverse fine decorations created by highly skilled master artisans. The watchmakers apply classic decorative techniques such as mirror polishing, beveling, circular graining, and “Côtes de Genève” to movement components hidden inside the watch and out of sight. The movements are engraved with the prestigious Hallmark of Geneva, an independent certification of the strict requirements regarding the timepiece's origin, precision, durability, and watchmaking expertise.

       Furthermore, to highlight the unique quality of these seven new limited-edition watches in the Harmony collection, they feature scroll-pattern decorations on the movement oscillating weight, chronograph bridge, or balance cock. This design is inspired by the balance cock of Vacheron Constantin's first pocket watch signed by Jean-Marc Vacheron in 1755. This exquisite decorative technique, also known as “fleurisanne engraving”, is exclusively applied to Vacheron Constantin's 260 anniversary special edition watches. Additionally, the backs of these unique timepieces are engraved with anniversary markings.

A Contemporary Interpretation of Haute Horlogerie Tradition

 

       The design of the Harmony collection is inspired by a historical classic from Vacheron Constantin, namely the brand's first chronograph introduced in 1928, a uniquely designed, extremely elegant, and highly sought-after complicated watch among watch enthusiasts. This newly introduced monopusher chronograph features a cushion-shaped yellow gold case, housing a movement with a diameter of 13 lignes, a white dial with a pulsometer scale around the edge, leaf-shaped hands, and painted Arabic numerals. The pulsometer chronograph was originally a medical instrument, allowing doctors and nurses to quickly read the heart rate based on 30 pulse beats using the chronograph hand. This chronograph from the Harmony collection is extremely similar to the historical model from 1928. The Harmony collection continues the aesthetic design of the 1928 model, and also incorporates the same ingenious monopusher mechanism inside as the 1928 model. Vacheron Constantin's designers and developers strove for perfection, going far beyond simply recreating a classic watch with modern technology. Every detail, every line, every curve, every feature, and every light reflection has been repeatedly considered, aiming to perfectly interpret Vacheron Constantin's traditional watchmaking skills in a contemporary way. Both technically and aesthetically, the Harmony collection fully captures the classic spirit of the 1928 chronograph, resulting in a refined and authentic work of art.

Horological Works of Art

       The Harmony collection reimagines the traditional cushion shape, featuring a case with a superimposed three-dimensional structure, while the movement housed inside is a distinctive haute horlogerie mechanism of unique construction, reliable quality, and outstanding performance.

       The Harmony collection watches feature a sophisticated and highly contemporary structure, with a curved case, a square-round bezel, and a circular crystal combining to present this sleek, multi-layered, and elegant case. The new collection is simple and pure, with an exquisitely designed case exterior that creates a rich sense of three-dimensionality. In addition, the streamlined lugs elongate the lines of the case, creating unique light and shadow effects. The exquisite watch structures created by Vacheron Constantin are comparable to sculptures, housing superbly crafted movements, striving to present a harmonious rhythm of straight lines, curves, planes, and light reflections, showcasing Vacheron Constantin's superb watchmaking art. Vacheron Constantin is a true master of watchmaking art, adept at using authentic artistic methods to present a unique watchmaking aesthetic and highlight the watch's most complex movement mechanisms. The perfect proportions of the watch design showcase Vacheron Constantin's top-tier watchmaking craftsmanship, highlighting its legibility, precision, and movement functions, while also allowing for the integration of a wide variety of complications. The new Harmony collection is destined to become a brand classic, a bold attempt to incorporate modern elements, and an extraordinary horological sculptural work of art created by combining watchmaking technology with decorative arts.

Refined Dial, Pure Elegance

 

        The medium and grand complication movements introduced this year are housed in exquisite cases that match their intrinsic excellence, paired with refined dials of perfect legibility. Inspired by a historical chronograph launched by Vacheron Constantin in 1928, the dial reinterprets this classic masterpiece, striving to preserve original design details while imbuing them with contemporary character. The dial design is breathtaking in its detail; the shape, font, and colour selection of the Arabic numerals have been meticulously considered to perfectly showcase the dial's distinct character and enhance its unique aesthetic charm. The bright silver dial is adorned with Arabic numerals and slender leaf-shaped hands, highlighting the extraordinary elegance and refinement of this monopusher chronograph. To create a work of pure originality, the blue numerals on the Harmony collection watches have been entirely redesigned and resized, lending the dial a distinctive, fluid quality while ensuring legibility. The positioning of the numerals and hands is precise, presenting a striking visual effect. While retaining the classic design and classical elegance of watches from the 20th century 20s, these designs also bestow the new Vacheron Constantin collection with its own unique identity. Re-examined and adjusted, the leaf-shaped hand design from the 1928 chronograph model appears for the first time in a contemporary Vacheron Constantin collection. The slender, elongated hands highlight the exceptional accuracy of these precision movements, with pure lines exuding a refined, classical charm. The delicate blue chronograph hand marks specific short-time measurement functions, making the dial display clearer and showcasing the intricate operation of the watch's complex mechanism. The vibrant red pulsometer and tachymeter scales on the minute track form a subtle contrast with the deep blue Arabic numerals and chronograph hands, further enhancing the legibility of the elegant and minimalist dial.

Horological Sculptures: The Artistic Aesthetic of Sculpting Time

       In tribute to the chronograph, Vacheron Constantin has introduced four movements: 3500, 3200, 3300, and 1142. For nearly a century, the chronograph function has been a significant complication in Vacheron Constantin's watchmaking tradition; as early as 1852, a Vacheron Constantin “medical” pocket watch was created featuring an independent seconds hand and a special scale on the dial. In 1873, Vacheron Constantin launched its first chronograph pocket watch, and in 1917, it was reduced to wristwatch size for the first time. These early pocket and wristwatches embodied the brand's specific requirements for mechanical timekeeping devices, namely the ability to measure extremely short intervals with high precision. Thus, since its founding, Vacheron Constantin has developed a professional watchmaking expertise in the research and development of highly technical complications and timepieces, producing watches that are accurate and capable of withstanding harsh environments or being used for scientific observation during maritime and aviation travel. Orders for Vacheron Constantin chronograph wristwatches with built-in anti-magnetic functions and precision timing devices between 1880 and 1910 fully demonstrate this, with demand coming from physicians, military observers, engineers, and the navy. Throughout its history, Vacheron Constantin has continuously refined and promoted its watchmaking skills, and this time, it has perfectly integrated the art of shaping time into the Harmony collection to meet the most stringent and specific requirements.

        The new Harmony collection draws its inspiration from the cushion-shaped case first introduced by Vacheron Constantin in the 20th century 20s, which housed a chronograph movement previously used in pocket watches. This collection features distinct lines that exude a strong modern feel, employing a unique aesthetic design to ensure the precision and legibility of the watch's complications. The complex structural design elevates the Harmony collection into the realm of horological sculptures, while the superb movements housed within demonstrate the multifaceted functions of the timepieces.

Chronographs: A New Interpretation of Traditional Craftsmanship

 

        The term chronograph is derived from the Greek words “ chronos (time) ” and “ graphien (recording tool) ”, meaning “ time recorder ”, and is designed specifically for measuring medium and short durations. The chronograph has realised one of humanity's oldest dreams—measuring time—and has inspired collectors and connoisseurs in the field of haute horlogerie to pursue speed and energy. Consequently, the chronograph has become one of the most sought-after types of complication since the birth of the mechanical wristwatch in the 20th century 80s. To present the brand's exceptional watchmaking tradition and write a new chapter in horological history, Vacheron Constantin has incorporated this complex and refined function into the first timepieces of the new Harmony collection. Since 2008, Vacheron Constantin's engineers, designers, and watchmakers, upholding the spirit of Jean-Marc Vacheron who founded his workshop in Saint-Gervais, Geneva, in 1755, have dedicated themselves to researching and creating many supreme timepieces featuring top-tier watchmaking expertise. From the brand's inception and the first pocket watch signed by Jean-Marc Vacheron to the launch of the Harmony collection, the 260 years have witnessed the birth of many of the world's most complex and sought-after chronographs, each marking the extraordinary imprint of Vacheron Constantin's traditional watchmaking skills. In 1917, this Geneva-based manufacturer launched its first chronograph wristwatch. Since then, Vacheron Constantin has continuously refined this complication, enabling the wearer to freely record personal time and operate the chronograph function in a comfortable, elegant, and effortless manner.

Innovation in Technology and Aesthetics

        For nearly two centuries, although chronographs have been extremely attractive to watch connoisseurs worldwide, their production process is extremely complex because chronograph movements consist of many intricate parts. Therefore, seven years ago, when Vacheron Constantin's R&D team began designing and creating new chronograph movements, the goal was to significantly utilise contemporary watchmaking materials and technologies to develop a movement with a classic structure. To continue the pure elegance and classicism of Vacheron Constantin's creations from the 20th century twenties and thirties, this chronograph had to be a monopusher design. Behind this seemingly simple chronograph lies a powerful complication, designed to allow the wearer to operate it with precision, ease, and comfort. The chronograph movement is equipped with a traditional column wheel and a horizontal coupling clutch, while incorporating highly original advanced devices, such as a “ dragging ” minute totaliser and a new type of “ friction ”technological horizontal coupling clutch. The latter solves the issue where pressing the chronograph button often causes a slight tremor in the chronograph seconds hand before timing begins. This redesign reduces or almost completely eliminates the slight tremor that often occurs before a chronograph starts timing.

        Vacheron Constantin has dedicated itself to developing a movement that is fully functional, reliable, durable and easy to operate, whilst striving for perfect design in the smallest details of the movement parts. For example, a conical gear is designed between the winding pinion and the crown wheel to ensure smooth and steady winding. In addition, these new movements benefit from the most cutting-edge watchmaking technology, with the chronograph wheel teeth delicately meshed at an interval of just 0.03 mm, ensuring that the gear play is kept to an absolute minimum. Other technical and aesthetic innovations put the finishing touches to these new movements, which blend visual aesthetics with technical excellence. The meticulously crafted exterior, the complex movement design, the Maltese cross-shaped chronograph gear, and the column-wheel screw adorned with the same brand emblem, all vividly interpret Vacheron Constantin's Haute Horlogerie craftsmanship.

Haute Horlogerie Craftsmanship and Anniversary Decoration

 

        Like all creations from Vacheron Constantin, the new movements powering the Harmony collection combine the most exquisite Haute Horlogerie craftsmanship and bear the prestigious Hallmark of Geneva. Among the various ingenious decorative techniques, the most eye-catching are the black or mirror polishing, beveling, circular graining and “ Côtes de Genève ”. The decorative details of the movement parts, including those invisible from the outside, are all handcrafted by dedicated master artisans. This not only requires meticulous attention to detail during the production process, but also a high level of proficiency and undivided concentration. The long-standing, relentless pursuit of superb craftsmanship and perfect quality makes original Vacheron Constantin Haute Horlogerie stand out among many brands. Inspired by this spirit, Vacheron Constantin has mastered more than ten different types of horological decorative techniques.

        To further enhance the exclusivity of the first watches in the new Harmony collection, these timepieces are issued in limited editions. Furthermore, to ensure that this collection leaves an eternal mark on this special anniversary in the brand's history, Vacheron Constantin has designed a unique movement decoration pattern specifically for the brand's 260 anniversary. The design team, which pays close attention to the watch's exterior, also had the privilege of designing an original pattern for the movement. This design is inspired by the balance cock of the first pocket watch signed by Jean-Marc Vacheron in 1755, which featured this type of arabesque decoration, also known as “ fleurisanne engraving ”. The fleurisanne engraving is applied to the balance cock, tourbillon carriage bridge or oscillating weight of the Harmony anniversary models.

Harmony Ultra-Thin Grand Complication Chronograph— 3500 Movement

 

        The new Vacheron Constantin Harmony Ultra-Thin Grand Complication Chronograph is the most important model in this collection, issued in a limited edition of 10 pieces, each individually numbered. The automatic movement powering this watch is only 5.20 mm thick, housed in a cushion-shaped case measuring just 8.40 mm thick, setting another world record for ultra-thin chronographs. Being able to create such a delicate and complex structure in such a confined space while ensuring its flawless precision is a testament to Vacheron Constantin's superb watchmaking expertise. The new 3500 automatic movement consists of 459 parts, some of which, like the tiny springs, are only 3/100 mm, all assembled and adjusted to perfection by Vacheron Constantin's highly experienced watchmakers.

        This automatic movement from Vacheron Constantin has a power reserve of approximately 51 hours and is equipped for the first time with an extraordinary peripheral rotor mounted on ball bearings. The 3500 movement, decorated entirely by hand in keeping with Haute Horlogerie traditions, can be admired at a glance through the transparent caseback. The peripheral rotor design also ensures that this world's thinnest automatic split-seconds chronograph movement remains exceptionally light and slim. The Harmony Ultra-Thin Grand Complication Chronograph is one of the exclusive models launched by Vacheron Constantin to celebrate the brand's 260 anniversary, which is why its peripheral rotor is also decorated with a scroll pattern designed specifically for this anniversary by the brand's designers. This unique pattern is executed in “ fleurisanne engraving ”, inspired by the arabesque pattern decorated on the balance cock of the first pocket watch signed by Jean-Marc Vacheron in 1755.

       Vacheron Constantin's new Harmony Ultra-Thin Grand Complication Chronograph features a split-seconds function for recording different time intervals starting simultaneously, with its movement and case being the thinnest in its class. The first automatic split-seconds chronograph developed in-house by Vacheron Constantin bears the prestigious Hallmark of Geneva, reinterpreting rounded, hand-bevelled bridges with internal angles that can only be finished by hand. In addition, the edges of the teardrop-shaped movement jewels are adorned with gold chatons. Every detail pays tribute to the aesthetic characteristics of Vacheron Constantin chronographs from the 20s and 20s.

 

        Development of the 3500 movement began in 2008, aiming to preserve the classic construction of the chronograph while using the latest technology to ensure reliability, ease of operation and a perfect presentation of the movement's aesthetics. This movement incorporates several advanced technologies developed by the Vacheron Constantin R&D team, such as the “ friction ” technology of the lateral coupling clutch, which ensures that when the chronograph function is activated, the chronograph seconds hand does not stutter as often happens with chronograph watches. Another major breakthrough is that the rotor wheel stops swinging once the mainspring is fully wound, thereby avoiding excessive tension on the winding spring. The conical gear design helps to improve gear meshing, making winding feel smoother and steadier for the wearer. In addition, the application of micro-technology in gear cutting helps to achieve extremely high tooth meshing, improving the gear transmission system. An ultra-thin non-spherical differential gear is used to display the power reserve without adding to the movement's thickness. The chronograph uses a “ dragging ” minute display, which reduces amplitude loss and thereby improves accuracy.

       The 3500 movement is housed in a precious 950 platinum cushion-shaped case, with its exquisite appearance perfectly matching its outstanding quality. The combination of the curved case, square bezel and round crystal presents a slender feel, with a unique and impressive structure. The bright silvered opaline dial features a deep red tachymeter scale around the edge, with the hour, minute, small seconds at 9 o'clock and power reserve display clearly legible. The blue Arabic numerals complement the blue chronograph hands, while elegant leaf-shaped hands precisely indicate the hours and minutes.

 

        This new ultra-thin grand complication chronograph makes an elegant debut as the inaugural piece of the Harmony collection, fully demonstrating Vacheron Constantin's masterly artistic expertise and interpreting superb watchmaking skills that blend tradition with modernity.

Harmony Tourbillon Chronograph — 3200 Movement

 

       The Vacheron Constantin Harmony Tourbillon Chronograph possesses multiple extraordinary qualities: elegance, allure, distinction, and rarity. Equipped with a brand-new manually wound 3200 movement, the timepiece stands out as a magnificent creation within the Harmony collection—a line that accommodates both medium and grand complication movements—making it deeply cherished by watch collectors and seasoned connoisseurs alike. This peerless new timepiece combines the elegant charm of a monopusher chronograph with the distinguished quality of a refined Maltese cross-shaped tourbillon, exclusively limited to 26 pieces, each bearing an individual serial number. Housed within a precious 950 platinum case, the Vacheron Constantin 3200 movement is adorned with the esteemed Geneva Hallmark, while its bar bridge is embellished with delicately hand-engraved scroll motifs. To accentuate the uniqueness of this Vacheron Constantin 260-anniversary model, the brand's designers specially incorporated “fleurisanne engraving”, inspired by the vine-like motifs carved onto the balance cock of the brand's oldest pocket watch bearing the signature of Jean-Marc Vacheron, dating back to 1755.

       Designed, developed, and manufactured entirely in-house by Vacheron Constantin, this new movement incorporates several technical breakthroughs achieved by the brand in enhancing precision, reliability, and complications, while simultaneously improving user control. The development of the 3200 movement began in 2008 with a clear and steadfast objective: to integrate cutting-edge watchmaking technology into a classic architecture. In addition to its traditional construction, Vacheron Constantin's new 3200 movement features a column wheel and a lateral coupling clutch, while the hours, minutes, small seconds, tourbillon, monopusher chronograph, and power reserve display functions are all exceptionally innovative.

       This new chronograph movement boasts numerous highlights. As a crowning touch, the development team designed a precise and reliable chronograph activation mechanism for the original 45-minute “ dragging ” minute counter (instead of the traditional 30-minute counter). In traditional movement structures, if the pusher is not pressed with sufficient force, the chronograph mechanism may sometimes be activated without actually starting properly. With this new system, the gears and cams only begin to rotate once the chronograph mechanism is truly engaged, thereby significantly improving the movement's durability and reliability. The lateral coupling clutch of the movement adopts a novel “ friction ” technology, preventing the chronograph seconds hand from experiencing the slight judder traditionally seen when the counter is activated. Furthermore, the lateral sliding pusher ensures that the user has superior control over the chronograph functions.

 

       To effectively enhance the precision of operational procedures, the counter replaces the traditional single hammer structure with a dual hammer configuration to handle the start, stop, and zero-reset functions. The zero-reset hammer exerts pressure on the heart-shaped cam, pushing it to rotate clockwise or anti-clockwise so that the hands return to zero. Once the stop-seconds lever returns to its initial position, the zero-reset hammer is also reset. Notably, the tapered gear between the winding pinion and the crown wheel ensures smooth and steady winding, while the spherical differential gear displaying the power reserve (also connected to the tapered gear) helps extend the movement's longevity. Thanks to modern production techniques, a major breakthrough has also been achieved in the design of the chronograph wheel and friction system: the teeth of the chronograph wheel are exceptionally fine, with a tooth spacing of only 0.03 mm, thereby ensuring minimal gear play. From the meticulously hand-engraved exterior and the complex movement design to Vacheron Constantin's signature Maltese cross chronograph wheel and the column-wheel screw adorned with the same emblem, every single detail eloquently interprets Vacheron Constantin's haute horlogerie craftsmanship.

       This manually wound mechanical complication movement boasts a power reserve of up to 65 hours and is composed of 292 parts, all of which are hand-decorated in adherence to the principles of fine watchmaking art. To clearly showcase the captivating rotation and “ dance” of the tourbillon at the 12 o'clock position, Vacheron Constantin's developers engineered an unusual rotational method for the tourbillon carriage. The tourbillon carriage of this timepiece is no longer driven by the seconds wheel, but is instead powered by an intermediate wheel operating the seconds hand. This arrangement allows the upper part of the bridge to provide the widest possible view of the tourbillon's elegance. To ensure quiet and smooth rotation, the Vacheron Constantin development team set the movement frequency at 2.5 Hz (18,000 vibrations per hour). This gentle and steady rhythm allows the light “ footwork” of the tourbillon to be fully admired through the wide opaline dial. Composed of 49 components—some of which have undergone mirror polishing—this ultra-light tourbillon weighs a mere 0.55 grams. The small blue screw on the Maltese cross rotates towards the outer rim of the carriage to indicate the seconds.

 

       This elegant and captivating complication timepiece features a newly refined, sculpture-like cushion-shaped case, paired with a delicate, pure, and impeccably legible dial. The blue Arabic numerals draw inspiration from a chronograph dating back to 1928, reinterpreting this classic design through a modern aesthetic that perfectly complements and echoes the blue hands tracking the chronograph functions. The dial perimeter is strikingly highlighted by a bright red minute track, while a pair of leaf-shaped hands glide gracefully across the face.

       Possessing unique and exceptional qualities, this new timepiece combines two highly prestigious and sought-after complications in the watchmaking industry, presenting a flawless synthesis of modern spirit and classical charm.

Harmony Chronograph — 3300 movement

 

       The entirely new Harmony chronograph collection reinterprets the classic charm of a Vacheron Constantin 1928 chronograph with a contemporary approach, paying special tribute to it. The pink gold cushion-shaped case of the watch is magnificent, and its three-dimensional structure houses the brand new Vacheron Constantin in-house developed 3300 manual-winding movement, once again reinterpreting the harmonious blend of pure artistry and exquisite craftsmanship. This single-monopusher chronograph movement boasts a power reserve of up to 65 hours, adopting the classic structure of the new movement introduced by Vacheron Constantin to commemorate its 260th anniversary, while benefiting from the brand's expertise in modern technology. This anniversary edition watch is a limited edition of 260 pieces, with each piece individually numbered. This watch features hour and minute display functions, a small seconds subdial at the 9 o'clock position, along with a single-monopusher chronograph function, pulse scale, and power reserve display. The outer edge of the dial features a dark red pulsometer scale, calibrated for 30 heartbeats as the unit of heart rate measurement, inspired by historical medical watches and paying tribute to the 1928 prototype. In addition, the balance cock is adorned with hand-engraved delicate scroll patterns, specially designed by Vacheron Constantin designers for the brand's 260th anniversary watch. This ornamentation, also known as “fleurisanne engraving”, is inspired by the vine patterns decorating the brand's first pocket watch signed by Jean-Marc Vacheron in 1755. The development of the 3300 movement began in 2008, upholding Vacheron Constantin's consistent design principles: creating a traditional chronograph equipped with a column wheel and horizontal coupling clutch, while endowing it with modern watchmaking technology, craftsmanship and aesthetic features.

 

       This brand-new chronograph movement has many highlights. As a finishing touch, the development team designed a precise and reliable chronograph activation device for the original 45-minute “ dragging ” chronograph counter (rather than the traditional 30-minute counter). In traditional chronograph movement construction, if the push-piece pressure is insufficient, the chronograph device may sometimes be activated but may not actually start properly. With this new system, only when the chronograph mechanism is truly engaged do the gears and cams begin to turn, thereby significantly improving the durability and reliability of the movement. The horizontal coupling clutch of the movement adopts a novel “ friction ” technology, ensuring that when the chronograph is activated, the chronograph seconds hand does not experience the slight judder seen in the past. In addition, the lateral sliding pusher ensures that the wearer has better control over the chronograph function.

       To effectively improve the precision of the chronograph mechanism, the counter uses a dual-hammer structure instead of the previous single-hammer structure to complete the start, stop and flyback functions. The zero-reset hammer exerts pressure on the heart-shaped cam, driving it to rotate clockwise or anticlockwise so that the hands return to their initial position. After the seconds-stopping lever returns to its initial position, the zero-reset hammer also resets. It is worth mentioning that the conical gear between the winding pinion and the crown wheel ensures smooth and steady winding, while the spherical differential wheel displaying the power reserve (also connected to the conical gear) extends the usage of the movement. Thanks to modern production techniques, a major breakthrough has also been achieved in the design of the chronograph wheel and friction system: the profile of the chronograph wheel is extremely precise, with tooth spacing of only 0.03 mm, thereby ensuring absolute minimum gear backlash. The exquisite exterior finishing, the intricate movement design, Vacheron Constantin's signature Maltese cross-shaped chronograph wheel, and the column wheel screw adorned with the same emblem, every detail thoroughly embodies Vacheron Constantin's haute horlogerie craftsmanship.

Harmony Chronograph Small Model — 1142 Movement

 

       This newly launched double-pusher chronograph from the Harmony collection elegantly reinterprets complications for women's watches. The Harmony Chronograph Small Model is paired with an elegant and imposing 18K pink gold cushion-shaped case, produced in a limited edition of 260 pieces, featuring individual product numbering. The bezel is set with top-tier sparkling diamonds with a total weight of approximately 1.20 carats. Powered by the manual-winding 1142 movement operating at a vibration frequency of 3 Hz, this watch drives the coveted haute horlogerie complication of a chronograph. As an enhanced version of the existing movement, the 1142 movement also boasts the Poinçon de Genève (Hallmark of Geneva) certification, operating at a high vibration frequency of 3 Hz (instead of 2.5 Hz), thereby increasing the shock resistance of the balance wheel.

       Comprising 164 components entirely finished by hand, this extraordinary movement features a power reserve of 48 hours, accurately displaying hours, minutes, small seconds, and chronograph functions. To pay tribute to Vacheron Constantin's continuous heritage of excellence in watchmaking technology and craftsmanship over 260 years, the movement's balance cock is decorated with original scroll patterns, highlighting the uniqueness of the exclusive Harmony collection models. Crafted meticulously by the brand's designers, this distinctive design is also known as “fleurisanne engraving”, inspired by the vine patterns found on the balance cock of the first Vacheron Constantin pocket watch signed by Jean-Marc Vacheron in 1755. Like all chronograph movements in the Harmony collection, the column wheel screw of this watch adopts Vacheron Constantin's signature Maltese cross emblem. Exquisite blue Arabic numerals, specially designed for Harmony watches, shine brightly on the silvered opaline dial, complemented by gold or blue leaf-shaped hands. Bearing the prestigious Hallmark of Geneva, this elegant chronograph blends a bold, novel design with a feminine touch, resulting in an exceptional piece of modern charm.

Harmony Dual Time — 2460DT Movement

 

       Extraordinary and richly contemporary, the Harmony collection is equipped with Vacheron Constantin's new in-house movements featuring exceptional complications to meet the desire for a refined lifestyle. Precise dual-time synchronisation is one of the most practical and sought-after complications among ladies and gentlemen of distinction. To meet customer demands, Vacheron Constantin has specially developed and manufactured a brand-new 2460DT automatic-winding movement dedicated to the essential dual-time function. Two new men's watches and one women's watch are powered by this new movement, driving the hours, minutes and seconds, along with the dual-time and day/night indication. To ensure the wearer enjoys an exceptional experience under any circumstances, this precision movement incorporates outstanding innovative technology, allowing all settings to be easily adjusted simply by rotating the crown clockwise or anticlockwise. This movement is also equipped with a special stop-seconds device for even more precise and effortless time-setting adjustment. In addition, the convex crown makes operation smoother and simpler.

       Like other watches in the Harmony collection, these three new dual-time models bear the Hallmark of Geneva, a guarantee of horological quality, fine craftsmanship, durability and expertise. The Harmony collection was specially introduced to celebrate the 260th anniversary of the founding of the brand, with both the dual-time and dual-time small model watches featuring a rotor decorated with a fine scrollwork pattern. Vacheron Constantin designers created this unique anniversary motif exclusively for this special collection, using a technique also known as “fleurisanne engraving”, with its design inspired by the first pocket watch bearing the signature of Jean-Marc Vacheron produced in 1755, when the balance bridge of that timepiece was decorated with this vine-patterned technique.

       The Vacheron Constantin 2460DT movement features a power reserve of 40 hours, consists of 233 parts, and is finished by hand entirely in accordance with the requirements of fine watchmaking tradition. The cushion-shaped cases of the two men's watches are grand and imposing, crafted in 18K white gold or 18K 5N pink gold. The case of the ladies' model is made of 18K white gold with more delicate dimensions, and the bezel is set with 88 fine diamonds totalling 1.20 carats. The silvered opaline dial is paired with gold or blue leaf-shaped hands and the distinctive blue Arabic numerals of the Harmony collection, ensuring that the wearer can clearly read local and dual times. The sun and moon symbols of the day/night indicator are made of yellow gold. The dual-time watch cleverly combines intrinsic functionality with an elegant appearance, reflecting the striking modern appeal of the new Harmony collection.
