Reference 278240-0014 houses a round 31 mm Oystersteel case built on Rolex's Oyster architecture, featuring a monobloc middle case, screw-down case back, and a screw-down Twinlock winding crown. Scratch-resistant sapphire crystal protects the dial, with a Cyclops lens positioned over the date window, and the watch is waterproof to 100 metres / 330 feet.
The pink dial is marked with Roman numerals, while the domed bezel frames the case with understated elegance. The Oystersteel Jubilee bracelet, composed of five-piece links, fastens via a concealed folding Crownclasp for a secure and refined fit on the wrist.
Inside beats the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex. It delivers a precision of -2/+2 seconds per day after casing — achieving Superlative Chronometer status through both COSC and Rolex certification — and offers a power reserve of approximately 55 hours. The oscillator features a Syloxi hairspring in silicon with patented geometry, complemented by Paraflex shock absorbers, while bidirectional winding is accomplished via the Perpetual rotor.
