Vacheron Constantin Fiftysix complete calendar

The Vacheron Constantin Fiftysix Complete Calendar 4000E/000R-B438 measures 40 mm in rose gold. The case stands 11.6 mm thick and is fitted with a sapphire crystal. Under the dial runs the self-winding calibre 2460 QCL/1, bearing the Hallmark of Geneva and delivering 40 hours of power reserve. The white dial shows day, date and month by aperture alongside a moon phase display, with luminous hands and indices for legibility. Central seconds complete the display, and a sapphire caseback reveals the movement. The watch is fitted on an alligator leather strap closed by a rose gold pin buckle. Water resistance is modest at 30 metres, in keeping with the dress-watch nature of the piece.
