Vacheron Constantin Ref. 2215 Royal Chronometer Automatic
Housed in a octagonal stainless steel or yellow gold case, the Vacheron Constantin 2215 is powered by the self-winding caliber 1096, which comes with a hacking function that allows for more precise time-setting. The timepiece is engraved with its running serial and case numbers on the outside of the caseback while the inside is engraved with the model reference and case numbers.
Decorated with three diamond-set numerals, the dial comes in either textured gold, textured silver or glossy black, and has a date aperture with metallic surround. There are also variations of this model without the diamond-set numerals, which feature applied baton indices instead. The integrated bracelet blends seamlessly into the angular geometries of the case, and appears to serve as the inspiration for the modern Vacheron Constantin Overseas.
