Vacheron Constantin Patrimony Perpetual Calendar Collection Excellence Platine Ref. 43175/000P-B190

In keeping with the aesthetic codes of the Collection Excellence Platine born in 2006, the SIHH 2016 Patrimony Perpetual Calendar is crafted in 950 platinum case, as is the dial. The latter features a finely grained sandblasted dial discreetly bearing the inscription “Pt50” between 4 and 5 o’clock. The slightly convex external zone is adorned with a circular “pearl” minute-track and 18K white gold applied hour-markers. The hours and minutes hands are in 18K white gold, while the calendar pointers are in blued steel. Setting the finishing touch, the saddle-finish dark blue alligator strap is hand-stitched with silk and 950 platinum threads, and secured by a folding clasp in the same metal.
