This Ref. 6715 embodies the grand Vacheron Constantin style: sobriety, extreme finesse, perfection of proportions. Designed as a horological jewel, it traverses decades without ever losing its appeal. Its 27 mm diameter, typical of the 70s–80s, makes it a naturally unisex watch, suited to all wrists.
The Caliber 1003, a monument of watchmaking, confers upon it a unique historical dimension.
