Measuring 31 mm across, the round Oyster case is crafted in White Rolesor — a combination of Oystersteel and white gold — and features a monobloc middle case with a solid screw-down case back. The bezel is set with diamonds, while a screw-down winding crown with Twinlock double waterproofness system and scratch-resistant sapphire crystal with a Cyclops lens over the date complete the case. Water resistance is rated to 100 metres / 330 feet.
The mint green dial features a Chromalight display with long-lasting blue luminescence for high legibility in low light. Date display with rapid setting and stop-seconds functionality for precise time setting round out the dial-side complications. Beneath the solid case back, the perpetual mechanical self-winding Calibre 2236 — a Manufacture Rolex movement — delivers a precision of -2/+2 seconds per day after casing, with a power reserve of approximately 55 hours. The oscillator incorporates a Syloxi hairspring in silicon with patented geometry, supported by Paraflex shock absorbers, and winding is bidirectional via the Perpetual rotor.
The watch is presented on an Oystersteel Jubilee bracelet with five-piece links, secured by a concealed folding Crownclasp. Reference 278384RBR-0022 carries COSC certification.
