The Yacht-Master takes the Oyster case into a register that is nautical rather than professional — the bidirectional bezel is for timing, not for the fail-safe arithmetic a diver needs. The Rolesium execution pairs Oystersteel with a solid platinum bezel, a combination Rolex uses nowhere else, and the platinum's grey does not tarnish or plate-wear the way a coating would. Date with Cyclops; water resistant to 100m. Calibre 2236 carries the silicon Syloxi hairspring. What matters on examination: bezel condition, since the raised platinum numerals scuff and cannot be refinished without losing definition; case and lug sharpness; bracelet stretch; and on Everose, that the alloy's colour is even across case and bracelet. Confirmed through the desk. Maker: Rolex. Reference: 268622-0002. Available through ELITA's private desk — verification review, discreet handling and storage. Price on request.
