Overview

The Vacheron Constantin Patrimony Moon Phase Retrograde Date, reference 4010U/000R-B329, unites two classical complications — a retrograde date and a moon-phase display — within the restrained, architecturally pure aesthetic that defines the Patrimony collection. Its 42.5 mm 18k pink gold case frames a silvered opaline dial whose clean layout allows both indications to read with immediate clarity. Calibre 2460 R31L, developed in-house, provides the mechanical foundation for this pairing of complications.

History

The Patrimony line has long served as Vacheron Constantin's expression of Geneva's most disciplined design tradition — flat, uncluttered cases and dials that foreground the movement's capabilities rather than ornamental flourish. Reference 4010U/000R-B329 entered the collection in 2017, extending the line's reach into combined calendar and astronomical complications. The choice of pink gold and a silvered opaline dial places the piece firmly within the warm, dressy register that Patrimony has cultivated across decades, appealing to collectors who prize legibility and material quality in equal measure.

Notable points

The 42.5 mm pink gold case is generously sized for the Patrimony line, lending the dial ample room for two distinct complications without visual crowding.
Calibre 2460 R31L is an in-house manufacture movement, reflecting Vacheron Constantin's status as one of the few maisons to produce its own complications-grade ebauches.
The retrograde date mechanism sweeps a hand along an arc before snapping back to the first of the month — a kinetic spectacle that contrasts with the dial's otherwise serene composition.
The moon-phase display is rendered on the silvered opaline dial in a manner consistent with Patrimony's tradition of restrained, classical decoration.
Introduced in 2017, the reference has remained a current part of the Patrimony catalogue, underscoring the enduring collector appetite for understated grand complications in precious metal.
