Day-Date 36 36mm Blue Ombré Roman Dial Diamond-Set Bezel President Bracelet - 128399TBR | 2024 Model 18ct White gold · Rolex 128399TBR

The Day-Date 36 ref. 128399TBR with its Blue Ombré Roman dial is one of the most visually extraordinary watches in Rolex's current production — the dial transitions from deep sapphire blue at the periphery through progressively paler shades toward the centre, a gradient achieved through proprietary lacquer layering that shifts appearance entirely under different light conditions. The 'TBR' designation identifies a Top Wesselton Brilliant Rainbow bezel, where each diamond is graded for a specific colour temperature to create a continuous spectral progression around the case — a gem-setting feat requiring Rolex to maintain vast stone inventories and exceptional colour-grading expertise in-house. Calibre 3255 — Rolex's most technically sophisticated movement with 70-hour reserve and Chronergy escapement — drives this 2024 piece, confirmed by box and papers. Among current Rolex references this is perhaps the most striking single watch the brand currently produces.
