This watch is in many ways interesting. The first is that it is the one-of-a-kind creation, the second reason is that this Vacheron Constantin timepiece goes with the Regulator movement.
I really like such type of time indication inspired by the precision clocks used to adjust watches from 17th century.
Presented as part of Vacheron Constantin’s Maître Cabinotier collection composed of exclusive timepieces, the Perpetual Calendar Regulator watch features a specific regulator-type time display. Its mechanical self-winding movement, Caliber 2460 RQP, was developed, designed and assembled by the master-watchmakers of the Manufacture so as to offer a distinctive reading of the hours and minutes that effectively complements the perpetual calendar functions.
With the Maître Cabinotier Perpetual Calendar Regulator model, Vacheron Constantin reinterprets this characteristic layout in an exquisitely refined contemporary spirit. The gold dial adorned with an opaline brown finish and a hand-guilloché motif provides a dissociated reading of time, swept over by slender leaf-type hands, “clous de Paris” hour-markers and Roman numerals. The fine guilloché pattern, epitomising the savoir-faire and creativity cultivated by Vacheron Constantin the domain of artistic crafts, calls for finishing work that is up to four times longer to perform and more demanding than on traditional dials.
Complementing the regulator-type display of the hours and minutes, the perpetual calendar and the moon phases appear on a snailed counter at 6 o’clock, while the pink gold moon and silver dust stars are sprinkled across this gently spiralling finish. The pink gold-rimmed day of the week and month apertures appear on either side of the offset hours counter at 12 o’clock. The various types of finish – guilloché, opaline, snailed and circular satin-finished – along with the alternating presence of applied hour-markers, Roman and Arabic numerals, combine to ensure excellent readability of each separate indication. This distinctively designed dial frames a 42 mm-diameter pink gold case that is water-resistant to 30 metres and topped by a concave bezel that accentuates the overall impression of slenderness.
The Maître Cabinotier Perpetual Calendar Regulator houses an exceptional mechanical heart. The new Caliber 2460 RQP was specially designed and developed by the master-watchmakers of the Manufacture in order to provide a regulator-type display of the hours and minutes. These indications are driven by a complex mechanism and the combination of complexity and original hour display has become an authentic brand signature. Its inherent originality is enriched by one of the most prestigious horological complications: the perpetual calendar, indicating the day of the week, the month, the date, leap years and moon phases. Comprising 334 carefully decorated components, this exclusive ‘motor’ beats at the frequency of 28,800 vibrations per hour and ensures a 40-hour power reserve.
