The Patrimony moon phase retrograde date model, presented in 2017 in white and pink gold versions, is one of Vacheron Constantin’s signature watches. Three years after its launch, this timepiece with its pleasing proportions is enriching the Collection Excellence Platine concept with a 50-piece limited boutique edition. Entirely faithful to the spirit of the Patrimony collection, drawing inspiration from the watches created by the Maison in the 1950s, this timepiece bears witness to the minimalist aesthetic approach of Vacheron Constantin. The timelessly elegant 42.5mm round case houses the self-winding Manufacture 2460 R31L calibre with its precision moon phase and retrograde pointer-type date display.
With its “Collection Excellence Platine” concept launched in 2006, Vacheron Constantin produces exceptional watches for collectors. Ranging from the simplest to the most complicated, all are offered in limited editions at a rate of one or two models per year. As its name suggests, their distinctive feature is 950 platinum, the watches being crafted in this noble metal from case to dial including the buckle while even the midnight blue alligator leather strap is hand-stitched with platinum and silk threads. The secret signature on sand-blasted dial of the Patrimony moon phase retrograde date watch is the inscription “Pt 950” between 4 and 5 o’clock.
This timepiece is powered by the Manufacture self-winding 2460 R31L calibre with a 40-hour power reserve. The transparent sapphire caseback provides a chance to admire this 275-part movement. The moon phases are displayed through an aperture at 6 o’clock, graduated from 0 to 29½, serving to count off the number of days elapsed since the last new moon. This horological complication, known as the age of the moon, corresponds to the actual cycle of this heavenly body, which rotates around the Earth in exactly 29 days, 12 hours and 45 minutes. The precision moon phases mechanism requires a one-day correction only once every 122 years. The second complication – a retrograde date indication by means of the central hand – occupies the upper part of the dial.
