Crafted from 18 kt yellow gold, the 42 mm Oyster case features a monobloc middle case, solid case back, and a screw-down winding crown equipped with the Twinlock double waterproofness system — delivering water resistance to 100 metres. The bidirectional rotatable fluted bezel integrates Rolex's Ring Command mechanism, allowing direct interaction with the movement's complications. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The intense white dial presents a Chromalight display with long-lasting blue luminescence for legibility in low light. Month is indicated through 12 apertures around the dial's circumference, while an instantaneous annual calendar sits at 3 o'clock alongside a 24-hour disc for the second time zone — all driven by the self-winding Calibre 9002, COSC certified to a precision of -2/+2 seconds per day and offering approximately 72 hours of power reserve. The paramagnetic blue Parachrom hairspring and Paraflex shock absorbers contribute to the movement's reliability.
The Oysterflex bracelet consists of flexible metal blades overmoulded with high-performance elastomer, secured by a folding Oysterclasp with the Rolex Glidelock extension system for a precise and comfortable fit on the wrist.
