The American 1921 was launched in 2008 and became the huge success we know of today, selling like hot cakes and one of the rare watches where there actually is a waiting list (waited 9 months for mine!!!)
Another version made in only 20 pieces available at the Vacheron Constantin boutiques was launches the same year: a perpetual calendar in a platinum case usung cal 1120.
As you may know clients can commission the Ateliers Cabinotiers, Vacheron Constantin’s bespoke watch department for a special watch and that’s what two collectors did: the wanted a perpetual calendar in platinum with a blue dial, numbered 1/2 and 2/2
And I’m pleased to show you these photos today.
Notice the crown which is pushed to the top left side of the case (contrary to the time only model which has the crown on the right), notice also the gorgeous hand engraved platinum moon phase (not available on the boutique special edition) which is currently available only in the perpetual calendar chronographs.
