Vacheron Constantin Maitre Cabinotier Perpetual Calendar Regulator is a regulator-type watch, inspired by the precision clocks used to adjust watches from the 17th century onwards.
The regulator-type display of the hours and minutes is complemented by perpetual calendar and moon phases indications: the pink gold-rimmed day of the week and month apertures appear on either side of the offset hours counter at 12 o’clock while the pink gold moon appears on a snailed counter at 6 o’clock. The small circular aperture positioned in the hours and minutes sub-dial at 4 o’clock indicates the leap year.
The gold hand-guilloché dial is adorned with an opaline brown finish and features slender leaf-type hands, “clous de Paris hour-markers and Roman numerals. The precious dial is framed by a 42 mm-diameter x 11.7 mm thick pink gold case that is water-resistant to 30 metres.
The mechanical heart of the timepiece is the new Caliber 2460 RQP that was specially designed and developed to provide a regulator-type display of the hours and minutes. Comprising 334 meticulously decorated components, the movement beats at the frequency of 28,800 vibrations per hour and ensures a 40-hour power reserve.
The Vacheron Constantin Maitre Cabinotier Perpetual Calendar Regulator is completed by a hand-sewn brown alligator Mississippiensis leather strap and delivered with a watch winder, a corrector pen and a magnifying glass.
