Reference 279171-0012 pairs a round 28 mm case crafted from Everose Rolesor with a chocolate dial whose diamond hour markers are individually set in 18 kt gold. The scratch-resistant sapphire crystal incorporates a Cyclops lens over the date window, while the monobloc middle case, solid case back, and screw-down winding crown with Twinlock double waterproofness system together deliver water resistance to 100 metres / 330 feet.
The Oyster bracelet, constructed from three-piece solid links in the same Everose Rolesor combination, secures via a folding Oysterclasp equipped with an Easylink 5 mm comfort extension link. The fixed bezel frames the dial with a fluted profile that echoes the two-tone material pairing throughout the watch.
Inside runs Rolex Calibre 2236, a perpetual, mechanical, self-winding movement certified as a Superlative Chronometer to a precision of -2/+2 seconds per day after casing. Its Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, and bidirectional Perpetual rotor contribute to an approximate power reserve of 55 hours, alongside a stop-seconds function for precise time setting and an instantaneous date with rapid setting.
