Like a good suit and tie, this is the Daytona that will work for any occasion. The Cosmograph Daytona was created to master the speed of timekeeping by featuring a chronograph, a 30-minute counter, and stop-seconds for a precise time setting. It has a 40 mm stainless steel case that has a screw-down case back, scratch-resistant sapphire with a winding crown. It has a black ceramic bezel with an engraved tachymetric scale. Enclosed in the case is the 4130 Caliber, which has bidirectional self-winding via Perpetual rotor, a-2/+2 sec/day precision and a 72-hour power reserve. The caliber has chronograph and small second functionality. The dial is black with highly legible hour markers and three black sub-dials with stainless-steel borders. It comes with an oyster steel president bracelet that has a folding oyster lock safety clasp. It has a water resistance of 100 meters (330 feet).
