Rolex Day-Date 36 Yellow Gold — Blue Ombré Dial, Diamond Bezel | Ref. 128349RBR

Reference 128349RBR is the Day-Date 36 in 18-carat yellow gold, completed here with a blue ombré dial and a diamond-set bezel — a combination that exemplifies the bolder, chromatic direction Rolex has pursued across its high-jewellery catalogue since the mid-2010s. The ombré treatment graduates from a deep sapphire blue at the periphery to a lighter, almost cerulean tone at the centre, exploiting the lacquering techniques developed by Rolex's dial-making subsidiary. The diamond-set bezel, replacing the traditional fluted or smooth profile, further amplifies the decorative register while maintaining dimensional continuity with the 36 mm case. The President bracelet in 18-carat yellow gold — exclusive to the Day-Date since 1956 — provides structural and aesthetic completion, with its three-piece semi-circular links conferring both comfort and considerable visual presence.

Calibre 3255 drives this 2024 production example, a movement that represents the current apogee of Rolex's mechanical engineering. Fourteen patents cover the 3255's construction, with highlights including the Chronergy escapement (which delivers approximately 15 percent better energy efficiency than conventional Swiss lever geometry), the Syloxi hairspring, Paraflex shock absorbers, and a 70-hour power reserve from twin series-coupled barrels. Superlative Chronometer certification guarantees -2/+2 seconds daily accuracy after casing.

Presented with original box and papers and rated as call-for-enquiry condition, this 2024 reference represents current production at retail. The 128349RBR designation's 'RBR' suffix indicates the diamond-set bezel configuration within Rolex's internal reference coding, distinguishing it from smooth and fluted variants of the same base case.
