Audemars Piguet recently introduced not only a new watch, but also the world’s thinnest, equipped with a perpetual calendar. The Royal Oak Selfwinding Perpetual Calendar Ultra-Thin paves the way for a new generation of complicated watches balancing refined aesthetics, optimum ergonomics, technical complexity, ancestral savoir-faire and contemporary lifestyle.

In designing this new watch, the Manufacture’s team paid particular attention to the development, design and ergonomics to boost the Royal Oak Selfwinding Perpetual Calendar Ultra Thin’s efficiency, robustness and reliability. The in-house calibre has been re-engineered to fit into the slim case, which glides under every shirt sleeve without the slightest effort and has optimised readability.

The Royal Oak Selfwinding Perpetual Calendar Ultra-Thin displays the perpetual calendar with day of the week, date, astronomical moon, month, leap year, day and night on its artfully designed dial. Hours and minutes are displayed from the center.
Compared to its predecessors, the watch has a completely new look. 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. In addition, the dial of the Royal Oak Selfwinding Perpetual Calendar Ultra-Thin is no longer endowed with a blue “Grande Tapisserie” pattern. Instead, its blue satin finishing enhances legibility as well as the watch’s refined aesthetics.

The Royal Oak Selfwinding Perpetual Calendar Ultra-Thin combines titanium and platinum for an elegant look and a significant lighter feel on the wrist. The alteration of polished and satin-brushed surfaces adorning the case, bracelet and bezel elevate the aesthetic contrast provided by the two materials.  The case is not only extremely flat but also has a very pleasant diameter of just 41 mm. The watch is water-resistant to 20 metres.

To reach this ultra-thin movement fo 2.89 mm in height, the perpetual calendar functions, normally arranged on three levels have been merged into one single layer. 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 automatic movement operates at 19,800 vibrations per hour and provides a power reserve of 40 hours.

Elegant appearance, lightweight feel and impressive technology – it’s impossible to ask more of a wristwatch.
