Swiss Haute Horlogerie manufacturer Audemars Piguet has introduced a new self-winding perpetual calendar movement, Calibre 7138, as part of its 150th-anniversary celebrations.
This innovative mechanism enhances user experience by allowing all adjustments via a single crown for the first time.
The perpetual calendar function, which automatically tracks varying month lengths and leap years, has been reimagined with ergonomics in mind.
Unlike traditional models that require small tools for manual corrections, Audemars Piguet’s new movement simplifies adjustments while maintaining the integrity of its intricate mechanical memory, which only requires intervention once every 100 years.
Calibre 7138 debuts in a 41 mm Code 11.59 by Audemars Piguet in 18-carat white gold, along with two 41 mm Royal Oak models in stainless steel and 18-carat sand gold.
Additionally, the anniversary limited editions each restricted to 150 pieces, feature subtle design elements honouring the brand’s heritage.
Developed over five years and protected by five patents, this movement also enhances water resistance, offering 50 metres for the Royal Oak models and 30 metres for the Code 11.59.
Audemars Piguet’s latest innovation combines cutting-edge research with traditional craftsmanship, reinforcing its reputation for technical excellence and refined aesthetics.
