Reference 279171-0023 pairs a round 28mm case in Everose Rolesor with a sundust dial featuring a Chromalight display and long-lasting blue luminescence. The scratch-resistant sapphire crystal is fitted with a Cyclops lens over the date, while the fixed bezel and solid case back give the watch its clean, enduring silhouette. The screw-down winding crown uses Rolex's Twinlock double waterproofness system, and the watch is waterproof to 100 metres / 330 feet.
Inside the monobloc Oyster case runs Calibre 2236, a perpetual, mechanical, self-winding movement manufactured by Rolex. The oscillator features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers, delivering a precision of -2/+2 seconds per day after casing and a power reserve of approximately 55 hours. Functions include centre hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time setting. The movement holds Superlative Chronometer status, reflecting both COSC certification and Rolex's own post-casing standards.
The three-piece solid-link Oyster bracelet is rendered in matching Everose Rolesor and fastens with a folding Oysterclasp equipped with an Easylink 5mm comfort extension link. This watch is offered unworn as a complete set, including the original Rolex box and Rolex papers.
