About the Watch
In 1971 Audemars Piguet realized that, without a disruptive change, a financial collapse was inevitable. Elaborating some feedback that they received from the Italian market about possible interest for a steel luxury watch, the management of the manufacture decided it was time to introduce something totally new, a sporty yet elegant timepiece as never seen before. The designer of choice for this task was a designer born in Geneva in 1931 from an Italian father and a Swiss mother: Gerald Genta. Not a new designer, rather one of the most famous watch designer at that time, having created successful watches for Universal Genève (Polerouter Microtors, White Shadow, Golden Shadow), Omega (Constellation) and Patek Philippe (Golden Ellipse).
Featuring a satin-finished gold dial, fewer than a few hundred examples were crafted in 18ct yellow gold before the introduction of the leap year indicator and tapisserie dial version in 1995. Powered by the world’s thinnest automatic perpetual calendar movement, this refined Royal Oak stands as one of the most collectible vintage complications ever produced by Audemars Piguet.
About the Brand
The Manufacture was established in 1875 in Le Brassus, a village at the heart of La Vallée-de-Joux in the Swiss Jura, by Jules-Louis Audemars and Edward-Auguste Piguet, two enterprising young men who combined their talent to develop and produce watches featuring rare complications. Already in these early days, an Audemars-Piguet watch was prized by admirers of fine mechanical timepieces. Through determination, imagination and discipline, they inscribed their name on the wider history of watchmaking. The company they established has never left the hands of the founding families.
