The Patrimony 4010U/000R-B329, seen from the bench

The Vacheron Constantin Patrimony 4010U/000R-B329 is a 42.5mm rose gold watch featuring a moon phase, retrograde date, and ultra-thin case profile. The lug width measures 18mm. The in-house caliber 2460 R31L is an automatic movement with peripheral micro-rotor, delivering a 40-hour power reserve. The dial presents hours, minutes, date, and moon phase in a harmonious composition, while the transparent caseback reveals finishes typical of Geneva haute horlogerie.
