Overview
Three dial variations on the retrograde moon phase
The Vacheron Constantin Patrimony Moon Phase Retrograde Date, reference 4010U/000R-B329, in 18K pink gold with a silver-toned opaline dial, on a brown alligator leather strap with a pink gold Ardillon buckle. Self-winding calibre 2460 R31L/1, with retrograde date and precision moon phase; 42.5 mm, 9.7 mm high, certified to the Hallmark of Geneva.
This execution is the Patrimony Moon Phase Retrograde Date on calibre 2460 R31L/1, in 18K pink gold with a silver-toned opaline dial. It comes on a brown alligator leather strap, closed by an 18K pink gold Ardillon buckle.
The reference 4010U is Vacheron Constantin's Patrimony Moon Phase Retrograde Date built on the self-winding calibre 2460 R31L/1. The outer zone of the dial carries a circular pearl-style minute-track set with 48 polished 18K gold pearls, and the moon-phase display shows two gold moon discs against what the brand calls a starry sky, alongside a retrograde hand-type date read by a blackened gold hand; hour-markers and the hour and minute hands are 18K gold throughout. The case measures 42.5 mm across and 9.7 mm high, water-resistant to 30 m, with a transparent sapphire case back.
Inside is the self-winding calibre 2460 R31L/1 -- 27.2 mm across, 5.4 mm high, 275 parts and 27 jewels, running at 28,800 V.P.H. (4 Hz) for a stated 40-hour power reserve. It drives the retrograde date alongside the moon-phase display, which the brand says needs correcting only once every 122 years. The watch is certified to the Hallmark of Geneva, a mark the brand dates to 1886, when the Republic and Canton of Geneva adopted it as a standard for well-finished watches, taken today as a sign of quality workmanship and origin rather than one single measurement.
