At the Origin of the Tourbillon
Patented in 1801, the tourbillon was developed to combat the harmful effects of earth’s gravity on the escapements of pocket watches held in a vertical position. While the arrival of wristwatches makes the tourbillon's role less clear, its creation requires greater expertise. Whatever the position of the watch, it is vital to achieve absolute precision in the rotating escapement.


Regulating the course of time, the spiral balance oscillates at a frequency of 2.5 Hz. This causes the escapement wheel to rotate on its axis 18,000 times per hour, or 5 vibrations per second. Ensuring high precision and durability, the lower-than-average speed makes it possible to enjoy the beating of the mechanism.

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.


THE ORIGINS OF SPORTY WATCHMAKING
The Overseas collection, reinvented in 2016, conveys the spirit of travel. This openness to the world, inherited from François Constantin, has remained at the core of the Maison’s philosophy ever since its founding. Designed in a spirit of casual elegance and comfort enhanced by their interchangeable strap/bracelet system, Overseas timepieces are the perfect daily companions.
