Released in October of 2016 in platinum, there is now a new version of this watch in 18K rose gold that was released at the SIHH 2017. The new Vacheron Constantin Traditionnelle Chronograph Perpetual Calendar ref. 5000T/000R-B304 is an exceptional timepiece in 18K rose gold that is as pure as it gets in terms of design and unequivocal elegance. Equipped with the new in-house Vacheron Constantin Calibre 1142 QP and cased in a generous 43 mm, the newest grand complication from Vacheron Constantin combines the chronograph and the perpetual calendar.
