Scaled to match your pace

This is our tachymetric scale, introduced in 1963 with the Cosmograph Daytona. Inscribed on the bezel, whether made from precious metals or in high-tech ceramic, it identifies the iconic model at a mere glance.

Could it be because of its most unfamiliar graduation? It runs in descending order, from 400 to 60, with units placed further and further apart… Though arrestingly cryptic, this irregularity allows for an immediate measure of speed, over a set distance, with remarkable precision. Start, then stop the chronograph, and the result can be read instantly. It’s simple. It’s fast. It’s to be used as you race towards your next achievement, to measure the breadth of your own performance.
