Overview

Two 270th-anniversary Patrimony moon phases

The Vacheron Constantin Patrimony Moon Phase Retrograde Date, reference 4010U/000G-H057, in 18K white gold with a silver-toned Maltese-cross-pattern dial, on a green alligator leather strap with a white gold Ardillon buckle. Self-winding calibre 2460 R31L/270, with retrograde date and precision moon phase; 42.5 mm, 9.7 mm high, one of 270 anniversary pieces.

The reference 4010U/000G is Vacheron Constantin's Patrimony Moon Phase Retrograde Date, a run of 270 pieces the brand ties to its 270th anniversary, offered in this 18K white gold case alongside an 18K pink gold execution on the same specification. The silver-toned dial carries a pattern the brand frames as inspired by the Maltese cross, laid across a convex outer zone, with gold moon discs for the phase display, gold applied hour-markers, gold bi-faceted baton hour and minute hands, and a blued gold hand for the retrograde date. Both executions measure 42.5 mm across and 9.7 mm high, water-resistant to 30 m with a transparent sapphire case back, on a green alligator leather strap closed by an Ardillon buckle in the case metal.

Inside is the self-winding calibre 2460 R31L/270, decorated with what the brand calls a côte unique finish and marked with an anniversary signature -- 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. Beyond the hours and minutes it drives a retrograde hand-type date and what the brand terms a precision moon phase, said to need correcting only once every 122 years. Both executions are certified to the Hallmark of Geneva; the brand traces the mark to 1886, when the Republic and Canton of Geneva adopted it as a mark of quality, standing today for provenance, craftsmanship and reliability in Geneva watchmaking.

For collectors

Each execution of this reference is limited to 270 pieces, marking the Maison's 270th anniversary, and both share the same calibre 2460 R31L/270, case size and case thickness -- they differ only in case and clasp metal, worth knowing when comparing the white gold against the pink gold example.
