The Vacheron Constantin Patrimony Moon Phase & Retrograde Date shares the pure lines, timeless elegance and authenticity that are the very essence of winter’s charm. This 18K 5N pink gold watch, powered by an in-house calibre, is graced with a dial depicting the cycle and age of the moon against a star-studded background, for which no correction is required for 122 years.

Vacheron Constantin associates this elegant combination with a retrograde date display stretching across the upper rim of the dial.
