History

Gerald Charles traces its lineage to the legendary Gerald Genta — the visionary designer behind the Audemars Piguet Royal Oak and Patek Philippe Nautilus — who launched his own brand in 1969. The octagonal case pays direct homage to Genta's celebrated motif. The Maestro collection channels his belief that a watch should be mechanically accomplished and architecturally distinctive. Compressing a perpetual calendar into 97 grams of grade 5 titanium positions Gerald Charles as a brand honoring its heritage while pushing into contemporary territory.
