Vacheron Constantin Traditionnelle Tourbillon Watch, 41mm Silver Dial, 6000T/000R-B346Patented in 1801, the tourbillon was developed to combat the harmful effects of earths 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.
