Entirely sculpted of 950 platinum, this model celebrates Vacheron Constantin's 270th anniversary. Its dial sports a bespoke hand-guilloché patterned dial while the calibre offers a classic "côte unique" finish on the bridges and a discreetly engraved anniversary signature. This limited-edition watch, 127 pieces total, runs on the Manufacture's new self-winding tourbillon calibre with a perpetual calendar. True to the Traditonnelle collection’s iconic styling, it has a stepped round case and lugs, a slender bezel and a fluted caseback, as well as a railway-type minute track and Dauphine-type hour and minute hands.
