Swiss Haute Horlogerie manufacturer Audemars Piguet is pleased to unveil a new Royal Oak Perpetual Calendar model, crafted in Grade 5 titanium. The new dial design pairs a blue “Grande Tapisserie” pattern with contrasting grey subdials, bestowing the model with a contemporary two-tone aesthetic.
CUTTING-EDGE AND REFINED AESTHETIC
The bracelet and case of the Royal Oak Perpetual Calendar are fully crafted in Grade 5 titanium – a tribute to the Manufacture’s uncompromising blend of high technology and ancestral craftsmanship. Often used for aerospace, motorsport and medical applications, this alloy is strong, lightweight, non-magnetic and highly resistant to corrosion.
Upholding fine watchmaking tradition, the ultra-light case and bracelet have been hand-finished with the Manufacture’s trademark alternation of satin-brushing and polished surfaces. Measuring 9.5 mm in thickness, this complicated timepiece also presents a slender profile.
The beauty of the titanium case and bracelet reside as well in their manufacturing complexity. Difficult to machine, this hard material causes milling tools to wear out more readily. Moreover, the milling speeds must be reduced to avoid any adverse heat damage to the alloy, thereby taking much longer to process than components formed of steel or gold.
The titanium case is enhanced with a new two-tone dial uniting a blue “Grande Tapisserie” pattern with smooth grey subdials matching with the hue of the case and bracelet for an elegant contrast and a unique play of light.
A SOPHISTICATED COMPLICATION
This limited perpetual calendar edition is powered by the selfwinding Calibre 5134, which automatically takes into account the number of days in the month and correctly displays the prevailing date even in leap years. Assuming the watch is kept fully wound, the date will not require manual correction until 2100, at which point it will require adjustment in order to stay in line with the Gregorian calendar.
The watch’s sapphire caseback reveals the refined decorations adorning the movement, which include “Côtes de Genève,” circular graining, circular satin and polished chamfers. The 22-carat gold openworked oscillating weight is further embellished with “Clous de Paris.”
