BACKSTORY

At the 19th Grand Prix d’Horlogerie in Geneva, Audemars Piguet won the prestigious Aiguille d’Or Grand Prix for its Royal Oak Selfwinding Perpetual Calendar Ultra-Thin. Judged as the most impressive watch across all categories at this “Oscars of watchmaking”, the 41mm timepiece is the brand’s latest technological milestone and was unveiled earlier this year. It’s powered by the self-winding manufacture Calibre 5133, which is a mere 2.89mm thick, and with a titanium case just 6.3mm high, it’s the world’s thinnest automatic perpetual calendar wristwatch. To achieve such dimensions, the perpetual calendar functions that are normally arranged on three levels have been merged into one layer, thanks to two patented innovations.
