Cosmograph Daytona John Mayer 40MM Oyster Bracelet Bright Green Dial 18 CT Yellow Gold Bezel With Engraved Tachymetric Scale

The Cosmograph Daytona was engineered to be the ultimate timing tool for endurance racing drivers, with its tachymetric scale, three counters, and pushers. The bezel features a tachymetric scale, allowing drivers to calculate average speed over a certain distance based on elapsed time.

This scale is easy to read, making the Cosmograph Daytona the perfect instrument for measuring speeds up to 400 units per hour, which can be shown in either kilometers or miles.
