Ready. Set. Go.

This is our chronograph. It enables time intervals to be measured with absolute reliability. Its starts and stops are instantaneous. START. Perfectly accurate. STOP. Without a twitch. RESET.

These reliable performances result from the efficient system embedded in the calibre 4131 of the Cosmograph Daytona. Its vertical clutch makes it possible to start and stop the time measurement function while sparing the chronometric precision over time. No matter how many times it is activated. Such is the prowess of our chronograph, leading the race in its field. START.
