Rolex Day-Date Gold — Ombré Diamond Dial | Ref. 128345RBR

The Day-Date 36 in 18 ct Everose gold with an ombré diamond dial, reference 128345RBR, represents the jeweller's art at its most technically demanding within the Rolex production universe. The dial is constructed from a graduated field of brilliant-cut diamonds set in a progressive tonal sequence — typically from deep brown or cognac at the periphery through to near-colourless at the centre, creating an optical depth that no lacquer or enamel dial can replicate. Each diamond is individually assessed, matched and set by hand within the Rolex manufacture, a process that demands precision tolerances across what may amount to hundreds of individual stones on a 36 mm dial surface.

The case, bezel and President bracelet are all executed in 18 ct Everose gold, the proprietary Rolex alloy whose platinum content stabilises the rose colour against the fading that affects lower-specification alloys. A fluted bezel in matching Everose gold encircles the dial with its characteristic vertical ridging, and the day display at twelve o'clock and date at three o'clock — the defining complications that give the Day-Date its name — are presented through windows in the pavé-set dial surface. The screw-down Twinlock crown maintains Oyster waterproofness to 100 metres, and a scratch-resistant sapphire crystal with Cyclops magnification over the date provides protection without optical distortion.

Calibre 3255 provides the mechanical foundation, the same movement Rolex employs across the current Day-Date 36 generation. Its Chronergy escapement, silicon Syloxi hairspring, and high-capacity barrel yield approximately 70 hours of power reserve and a frequency of 28,800 vph. The Perpetual rotor winding system maintains operational readiness under typical wearing conditions, and the stop-seconds mechanism allows synchronisation to the second. The 18 ct Everose gold President bracelet with its concealed folding Crownclasp provides the definitive wrist presentation for what remains, by any measure, the most prestigious watch in the Rolex catalogue.
