Rolex, Day-Date 36, 128239, Mother of Pearl Diamond Dial, White Gold, Presidential Bracelet, 36mm

The case is produced in 18ct white gold and measures 36mm, offering a compact proportion that carries a noticeably solid weight due to the density of the metal.

Its Oyster construction is built around a monobloc middle case, supported by a screw-down caseback and Twinlock crown system, forming a sealed structure rated to 100 meters of water resistance.

The fluted bezel is cut directly into the white gold, where each ridge creates a sharper, more restrained reflection compared to warmer metals, giving the outer edge a more controlled appearance.

The dial is crafted from white mother-of-pearl, a natural material that varies in tone and structure depending on its origin, so no two dials are visually identical.

Rather than being treated or artificially colored, the surface retains its natural characteristics, allowing subtle shifts in color and texture to emerge under changing light conditions.

Diamond hour markers are set in 18ct gold mounts, with baguette-cut diamonds positioned at 6 and 9 o’clock, introducing a more geometric structure within the organic dial surface.

The day display spans across 12 o’clock, while the date window at 3 o’clock is magnified through the Cyclops lens, ensuring both functions remain clear against the reflective dial.

A President bracelet in matching white gold completes the watch, featuring semi-circular three-piece links that allow for a more adaptive, fluid fit on the wrist.

The concealed Crownclasp integrates into the bracelet, maintaining a continuous metallic surface without exposing the fastening mechanism.

The watch is powered by the Rolex caliber 3255 automatic movement, engineered with an optimized escapement and improved energy efficiency.

It provides approximately 70 hours of power reserve and supports instantaneous day-and-date transitions, maintaining consistent performance during extended wear.

The contrast between the structured diamond layout and the unpredictable nature of mother of pearl creates a balance between precision and variation, where the dial never appears exactly the same from one moment to the next.
