Vacheron Constantin Patrimony moon phase retrograde date

Heir to the Maison’s great stylistic and technical tradition, the new Patrimony moon phase retrograde date watch also favours timeless understatement, with a 42.5 mm white gold case featuring a new dial colour. The sunburst old-silver-toned shade creates a subtle contrast with the pink gold of the hands and hour-markers, giving a two-tone twist to this model driven by in-house self-winding Calibre 2460 R31L powering two complications. The first is a moon-phase indication in an aperture at 6 o'clock, graduated to correspond precisely to the moon's cycle of 29 days, 12 hours and 45 minutes. This precision moon phase requires just one correction every 122 years. The second consists of a retrograde date display in the upper part of the dial, a Vacheron Constantin technical and style signature. Through the sapphire crystal caseback, this in-house calibre displays the emblem of the Maison: a Maltese cross whose shape has inspired that of the openworked 18K gold oscillating weight.

The elegant, pared-down and visually harmonious new Patrimony moon phase retrograde date watch also adopts a new dynamic, enlivening the wrist with an original touch of colour thanks to the new olive-green alligator leather strap.
