Rolex Watchmaking – Tachymetric Bezel

Our tachymetric scale, introduced in 1963 with the Cosmograph Daytona. Inscribed on the bezel, whether in precious metal or high-tech ceramic, it identifies the model at a glance. Its unfamiliar graduation runs in descending order, from 400 to 60, with units further and further apart, enabling an instant measure of speed over a set distance. Start, then stop the chronograph for an instant reading. To be used as you race towards your next achievement, to measure the breadth of your performance.
