The Manufacture’s R&D team has integrated movement development, design and ergonomics in the conception of this new timepiece to boost its efficiency, robustness and reliability. The result? An ultra-thin selfwinding perpetual calendar wristwatch equipped with a complex movement re-engineered to integrate an elegant ultra-thin case, perfectly fitting under the sleeve of a shirt and endowed with a refined dial design enhancing visibility.
To reach an ultra-thin movement of 2.89 mm in height, the perpetual calendar functions, normally arranged on three levels have been merged into one single layer. This led to the development of two pioneering and patented innovations: the end-of-the-month cam has been integrated to the date wheel, while the month cam has been combined to the month wheel. The geometry of each component has also been optimised from the onset, reducing adjustment and assembly time. The dial, too, has been redesigned compared to previous Royal Oak Perpetual Calendar models. The day, date and month subdials have been enlarged for optimum legibility, while the night and day indication at 8 o’clock has been added symmetrically to the leap year indication positioned at 4 o’clock.
Not only is this new line of timepiece thinner and more efficient than ever, it also combines titanium and 950 platinum for an elegant look and a significantly lighter feel on the wrist. Expertly assembled by Audemars Piguet’s craftsmen, its blue satin finishing further enhances legibility as well as the watch’s refined aesthetics.
