Rolex's latest Oyster Perpetual Day-Date II

       The latest Oyster Perpetual Day-Date II from Rolex is the embodiment of prestige and technical excellence. Designed for those with a discerning eye for the finest things, this new model also carries on the tradition of the first Day-Date introduced in 1956. As an ode to passion and charm, the new Oyster Perpetual Lady-Datejust 31 highlights the sophisticated coordination of tones and materials, boasting not only a novel character and high jewellery flair, but also incorporating the numerous exquisite technologies exclusive to the Oyster collection.

Flawless gem-setting craftsmanship

       The Day-Date II's 18 ct gold case was first introduced in 2008, and is now paired with a new champagne dial set with 8 baguette-cut diamonds, along with two baguette-cut rubies positioned at the 6 and 9 o'clock positions. It is further equipped with a sparkling bezel set with 80 square-cut diamonds. The shimmering gemstones interplay with the polished, brilliant gold, adding an air of grace and distinct personality to this timepiece. The Lady-Datejust 31 is similarly crafted from 18 ct gold, with its new sparkling bezel set with 48 diamonds, while the fresh champagne dial features 8 diamonds, and the two Arabic numeral hour markers at 6 and 9 o'clock are made from 18 ct gold and each set with 16 rubies.
Rolex Gold
        The cases and solid bracelets of both timepieces are cast and crafted in Rolex’s own foundry. Furthermore, the shaping, machining, and polishing processes receive meticulous care, allowing the 18 ct gold to emit its signature radiant glow.
Oyster Case – A Symbol of Outstanding Water Resistance

       The Oyster cases equipped on the Day-Date II and Lady-Datejust 31 guarantee water resistance up to 100 metres, serving not only as a model of elegant style, but also as a guarantee of precision and durability. The distinctive middle case is cast from a single block of 18 ct solid gold. The case back is screwed down using special tools by Rolex watchmakers, completely sealing the case. The winding crown employs a patented Twinlock waterproof system, securely screwed down against the case. The crystal is made of scratch-resistant sapphire, featuring a Cyclops lens at the 3 o'clock position for easy date reading. The completely sealed Oyster case provides optimal protection for the precision movement.
Superlative Chronometer
        The Day-Date II is equipped with the 3156 calibre automatic mechanical movement, entirely developed and manufactured by Rolex. As the heart of the timepiece, its balance wheel features Rolex's patented blue Parachrom hairspring, manufactured in-house from a unique alloy. This hairspring is impervious to magnetic fields and remains extremely stable through temperature variations, offering ten times the shock resistance of traditional hairsprings. Equipped with Rolex's patented Paraflex shock absorbers, shock resistance is increased by 50%. The Lady-Datejust 31 utilises the 2235 calibre automatic mechanical movement, entirely developed and manufactured in-house by Rolex. Like all Perpetual movements, both calibres have received official chronometer certification. This certification is exclusively awarded to precision watches that successfully pass the Swiss Official Chronometer Testing Institute (COSC) tests. The construction of this movement, like all Oyster movements, is both precise and reliable.
Prestigious and Elegant Bracelet
Whether the President bracelet of the Day-Date II or the Oyster bracelet of the Lady-Datejust 31, both are crafted from 18 ct solid gold and fitted with a Crownclasp. The Day-Date II's President bracelet features prestigious three-piece solid semi-circular links, offering exceptional wear comfort while fully matching the aesthetic identity of this collection. Meanwhile, the solid-link Oyster bracelet belonging to the Lady-Datejust 31 is also developed and patented by Rolex, ensuring comfortable wear and effortless operation.
