Cosmograph Daytona collection was introduced in 1963 for professional racing drivers to keep time. Rolex Cosmograph Daytona replica watches with black bezels are driven by 4130 Calibre, self-winding mechanical movements with paramagnetic blue Parachrom hairsprings that can save 7-hour power.
The diameter of 18ct everose gold cases is 40mm. The hour markers consist of everose gold settings and white mother of pearls. The central three hands show the time. There are two small dials for recording 30 minutes and 12 hours at 3 and 9 o’clock. There is also a small second dial at 6.
If a racing driver records time with this watch in a match, he can know the spent hours and minutes clearly from the two chronographs. The chronograph functions will start with just one click of the button. The Cerachrom ceramic black bezels with scales can help to measure the speed.
Rolex copy watches with black leather straps have scratch-resistant sapphire glasses protect the delicate dials. The screw-in crowns have triple locks and waterproofness systems. Their complicated functions and classical designs make them great in demand.
