Measuring 37 mm across, this Yacht-Master is built around a round monobloc middle case in 18kt Everose gold, sealed by a screw-down case back and screw-down Triplock winding crown for water resistance to 100 metres. The scratch-resistant sapphire crystal features a Cyclops lens over the date, while the bidirectional rotatable bezel carries a matt black Cerachrom ceramic insert with polished raised numerals and 60-minute graduations.
The intense black dial is complemented by the black Oysterflex strap — constructed from flexible metal blades overmoulded with high-performance elastomer — and secured by a folding Oysterlock safety clasp with Rolex Glidelock extension system. Inside, the perpetual mechanical self-winding Calibre 2236 offers a power reserve of approximately 55 hours, a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, and a precision rating of -2/+2 seconds per day after casing. The movement holds Superlative Chronometer status, reflecting both COSC certification and Rolex's own post-casing standards.
Reference 268655-0017 is presented with its Rolex card and Rolex box.
