Housed in a 40 mm monobloc 18 kt yellow gold Oyster case, this Daytona features a screw-down caseback, a screw-down Triplock winding crown, and scratch-resistant sapphire crystal rated waterproof to 100 metres. The black monobloc Cerachrom bezel in ceramic carries a moulded tachymetric scale, lending the watch its iconic motorsport character.
The bright black and golden dial is set with diamonds in 18 kt gold settings, while Chromalight display elements provide long-lasting blue luminescence for legibility in low light. Power comes from Calibre 4131, a COSC-certified perpetual mechanical self-winding chronograph with a paramagnetic blue Parachrom hairspring, high-performance Paraflex shock absorbers, and a bidirectional Perpetual rotor delivering approximately 72 hours of power reserve at a precision of -2/+2 seconds per day after casing.
The watch rides on an Oysterflex band — flexible metal blades overmoulded with high-performance elastomer — secured by a folding Oysterlock safety clasp with Rolex Glidelock extension system. Chronograph functions include a centre seconds hand, a 30-minute counter at 3 o'clock, and a 12-hour counter at 9 o'clock, with stop seconds for exact time setting.
