Reference 279171-0028 brings together a round 28mm case crafted in Everose Rolesor, pairing Oystersteel with Everose gold in the signature Rolex manner. The Oyster architecture employs a monobloc middle case, solid case back, and screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres. A scratch-resistant sapphire crystal with a Cyclops lens over the date completes the case.
The rosé-colour dial is set with diamonds in 18 kt gold settings, while the Roman IX marker is rendered in 18 kt gold and set with 8 diamonds, lending the face a refined, jewelled character. The Oyster bracelet, built from three-piece solid links in Everose Rolesor, fastens via a folding Oysterclasp with an Easylink 5mm comfort extension link.
Power comes from the Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex, featuring a Syloxi silicon hairspring with patented geometry, Paraflex shock absorbers, bidirectional winding via a Perpetual rotor, and a power reserve of approximately 55 hours. Precision is rated at -2/+2 seconds per day after casing, and the movement holds Superlative Chronometer certification reflecting both COSC and Rolex's own post-casing standards. This example is unworn and comes as a complete set with Rolex box and Rolex papers.
