The Patrimony moon phase retrograde date model, presented in 2017 in white and pink gold versions, is one of Vacheron Constantin's signature watches. Its understated elegance and the originality of its display embody the Maison’s identity at first glance. 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 with a concern for detail aimed at achieving perfectly balanced lines. The timelessly elegant 42.5 mm round case houses the self-winding Manufacture 2460 R31L calibre with its precision moon phase and retrograde pointer-type date display. For optimal user-friendliness, all function settings are performed via the crown.
