Fiftysix Complete Calendar
A pink gold Fiftysix with day, date and month apertures and a moon phase.
The Fiftysix recalls a Vacheron Constantin model from 1956. This one is 18K pink gold, 40 mm across.
The silver-toned dial shows the day, the date and the month. A moon phase with gold moons on a blue night sky is accurate over 122 years, and the date hand is blue to match.
A 22K gold oscillating weight in the shape of the Maltese cross shows through the caseback. The case is 11.6 mm thick.
