Specifications

About this reference

This timepiece, its case entirely sculpted in 950 platinum, brings together mechanical prowess and avant-garde vision. Issued in a limited edition of 370 pieces for Vacheron Constantin’s 270th anniversary, the watch sports a discreet anniversary signature and a "côte unique" finish. An openface dial adorned with a hand-guilloché Maltese cross pattern reveals the beauty and power of its new self-winding movement. A perpetual calendar boasts a retrograde date as well as a high-precision moon phase, while the Traditionnelle Collection’s classic styling is fully upheld: a stepped round case and lugs, slender bezel and fluted caseback, railway-type minute track and Dauphine-type hour and minute hands.
