Crown Setting Adjustment
The quest for ultimate perfection has been carried down to the smallest detail in the pursuit to design a caliber which is perfectly functional, reliable and attractive for its owner. The ability to easily adjust all the functions using just the crown offers both user comfort and visual satisfaction.


The age of the moon accurately determines the time that has elapsed since the new moon. Displayed on the dial by a graduation ranging from 1 to 29½ days, the indicator corresponds to the duration of the time it takes for the Moon to orbit the Earth. The moon progression is reflected on the wrist with precision.

PERSONALISE YOUR WATCH WITH A STRAP
Whether it’s the color of the leather, the color of the stitching or the color of the side edges, the possibilities are almost endless to make your watch strap entirely unique. You can also add a design or text to the lining of your watch to make it even more special. The strap bar: a tailored appointment for you to discover in the Vacheron Constantin Boutiques.


A GREAT WATCHMAKING CLASSIC
Circular perfection, a quest for essentials: the Patrimony collection is the epitome of stylistic pureness. Reflecting a deliberately minimalist approach striking a beautiful balance between taut lines and curves, it asserts its personality through slender cases radiating an elegance inspired by 1950s Vacheron Constantin models.
