Openwork Weight in 22-Carat Gold
When the watch is turned over, the quintessential art of watchmaking is revealed. The open caseback of the watch shows the sophisticated design of the caliber, revealing a 22-carat gold oscillating weight inspired by Vacheron Constantin's iconic Maltese cross. With the weight visible, the beauty of the mechanism and its exceptional finish are a testament to the Maison's expertise, accumulated without interruption since 1755.


Before time was broken down into hours, minutes and seconds, man tracked time by the movement of the stars. The sun's path marked the days and seasons, while the moon made it possible to know the passing of the months. A union of beautiful aesthetics and watchmaking performance, this poetic complication is represented by a moon disc with two polished moons in 18-carat gold.

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.


INTERPRETING MODERN ELEGANCE
A name and a date evoking an iconic model by Vacheron Constantin dating from 1956. This modern, elegant and relaxed collection with its resolutely cosmopolitan style expresses its personality through the contrast between the classic dial and the daring case. The latter is notably inspired by the Maltese cross-shaped emblem of the Maison that is also picked up on the openworked pink gold oscillating weight.
