Inspired by the historical precision regulators, the distinctive design of this model emphasizes chronometric accuracy by displaying minutes with a center minute hand and the hours and seconds in secondary sub dials. This new rose gold version, with its striking dial in graphite and ebony-black with a vertical satin finish, discreetly displays an annual calendar which takes into account months of 30 and 31 and requires a correction only once a year. To further emphasize chronometric precision, this model caliber 31-260 REG QA incorporates Patek Philippe Advanced Research Pulsomax® escapement and a Spiromax® balance spring in Silinvar®.
