Audemars Piguet Royal Oak Black Ceramic Perpetual Calendar Watch Review

　　Ceramic has outstanding scratch and wear resistance, can withstand high temperatures and thermal shock, and has excellent ageing resistance, making it a very suitable material for watch manufacturing. However, due to the extreme difficulty of hand-finishing, it is more challenging to process than ordinary metals, which may be why ceramic has not become the primary choice for watch cases, as the processing costs are higher. Using ceramic for a watch case is perhaps most complex forAudemars Piguetthe Royal Oak, which is the most complex. Due to its unique shape and multiple facets, its iconic octagonal bezel requires 70 manual finishing steps to polish and buff the eight bevels after being cut into shape. The monobloc case still requires 44 steps to complete the satin-brushed finish after the stamping process, and switching to ceramic requires even greater patience and skilled craftsmanship from the watchmaker. Last yearAudemars Piguetlaunched the Royal Oak Perpetual Calendar, and this year it introduced the black ceramic version (model 26579CE.OO.1225CE.01), further enriching its perpetual calendar collection. Within the 41 mm black ceramic case, the dark grey 'Grande Tapisserie' patterned dial clearly displays the date, day, month, astronomically precise moon phase, the week display on the outer rim of the dial, and the leap year display, which is the essence of the perpetual calendar function. Through the glare-proof sapphire crystal caseback, the wearer can fully appreciate the mechanical beauty of this in-house movement. Let us now appreciate the uniqueness of this watch.

　　Audemars Piguet Royal Oak Black Ceramic Perpetual Calendar Watch Introduction

　　The crown is also made of black ceramic; the octagonal crown remains complex in its craftsmanship.

　　The bracelet is the most difficult part of the entire watch to process. The craftsmanship of the integrated Royal Oak bracelet is extremely complex, with 138 edges on the links of varying lengths that require manual polishing and buffing. It takes 6 hours to machine, hand-finish, assemble, and adjust a stainless steel Royal Oak series bracelet, while producing the same style of black ceramic bracelet takes as long as 30 hours.

　　The case thickness is only 9.5 mm, with knife-like edge finishing and brushing, all of which require a considerable amount of working hours.

　　The dark grey Grande Tapisserie patterned dial is paired with black subsidiary dials and displays an astronomically accurate moon phase using a real lunar image, creating a sharp contrast with the black components. The date display is at the 3 o'clock position; the day of the week is at 9; the month and leap year are displayed at 12; and the outer ring displays the 52 weeks of the year, indicated by a white arrow-tipped hand.

　　Audemars Piguet's new Cal.5134 automatic mechanical movement is based on the Cal.2120 calibre. The very first Royal Oak produced by Audemars Piguet used the Audemars Piguet Cal.2120 calibre, featuring no seconds hand, a diameter of 39 mm and a thickness of 7 mm; this movement remains one of the finest automatic ultra-thin movements to this day. Cal.5134 has been modified and enlarged to fit the 41 mm case, featuring a suspended barrel adorned with circular Côtes de Genève, all bridges are bevelled and decorated with Côtes de Genève, and the 22K gold oscillating weight is engraved with the Audemars Piguet signature while its outer rim is decorated with a tapisserie pattern echoing the iconic dial design of the Royal Oak collection.
