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. The dissociated indication of the hours and minutes, ensuring immediate legibility, is inspired by the regulator-type clock that were used to adjust watches from the late 17th century onwards. Also called “master clocks”, these high-precision timekeeping instruments served as a point of reference in the watchmaking workshops and astronomical observatories of the time. An elegant hand-guilloché dial, reflecting the expertise faithfully passed on from generation to generation at Vacheron Constantin since 1755, endows the Maître Cabinotier Perpetual Calendar Regulator with a subtle aura of refinement, while its meticulous finishing enhances the perfect clarity of the indications. Created in a one-off edition, this prestigious timepiece harks back to the tradition of technical excellence and innovation cultivated by the 18th century cabinotiers. These highly specialised Geneva artisans in their attic workshops created authentic made-to-order masterpieces intended for prestigious customers from around the world. In harmony with this blend of horological prowess and extreme personalisation, the art perpetuated through the Maître Cabinotier Collection by Vacheron Constantin is reflected in the highly exclusive production of its “Atelier Cabinotiers” which creates bespoke Haute Horlogerie watches.

Precision and legibility at the heart of a distinctive display

Born of the expertise nurtured by the master-watchmakers of the Manufacture Vacheron Constantin, this unique creation features a characteristic display of the hours and minutes, inspired by the regulator clocks that first appeared in the 17th century. 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.
