Housed in a 40 mm 18 kt white gold Oyster case, this Cosmograph Daytona features a monobloc middle case with a screw-down case back and screw-down Triplock winding crown, offering water resistance to 100 metres. The bezel is set with diamonds, while scratch-resistant sapphire crystal protects the dial beneath.
The dial itself presents white and black mother-of-pearl with diamonds set in 18 kt gold settings, and the Chromalight display delivers long-lasting blue luminescence for readability in low light. The Oysterflex bracelet is constructed from flexible metal blades overmoulded with high-performance elastomer, secured by a folding Oysterlock safety clasp with the Rolex Glidelock extension system.
Powering the watch is the Calibre 4131, a perpetual mechanical self-winding chronograph manufactured by Rolex, with bidirectional winding via a Perpetual rotor, a paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, a power reserve of approximately 72 hours, and Superlative Chronometer certification reflecting both COSC and Rolex standards after casing, with a precision of -2/+2 seconds per day.
