Rolex, Day-Date 40, 228239, Meteorite Diamond Dial, White Gold, Presidential Bracelet, 40mm.

The watch is crafted in a 40mm Oyster case made from 18ct white gold, giving the overall design a cooler and more understated appearance that places greater emphasis on the unique dial material.

Its Oyster construction incorporates a screw-down caseback and Twinlock winding crown, maintaining water resistance up to 100 meters while preserving the balanced proportions of the Day-Date 40.

The fluted bezel surrounds the dial with sharply defined ridges that create controlled reflections around the perimeter of the case.

At the center is a meteorite dial, produced from a slice of iron meteorite that formed over millions of years as it cooled slowly in space.

This natural process creates the distinctive Widmanstätten pattern, a crystalline structure that cannot be artificially reproduced, making every dial visually unique.

Unlike lacquered, stone, or sunray-finished dials, the texture is not applied to the surface but exists within the material itself, creating intricate geometric patterns that vary from one watch to another.

Applied white-gold hour markers maintain legibility without obscuring the meteorite's natural structure.

The day display spans across 12 o’clock, while the date aperture at 3 o’clock is magnified through the Cyclops lens for improved readability.

Its President bracelet is crafted in matching white gold, using semi-circular three-piece links designed to contour naturally around the wrist while maintaining a substantial yet balanced feel.

A concealed Crownclasp integrates directly into the bracelet, preserving a continuous metallic appearance when secured.

Inside, the watch is powered by the Rolex caliber 3255 automatic movement, offering approximately 70 hours of power reserve and regulated to Rolex’s Superlative Chronometer standard.

The meteorite diamond dial gives this reference a level of individuality that extends beyond color or finishing.

Every pattern was formed long before the watch itself existed, meaning no two examples share the exact same surface, making the dial as much a natural artifact as it is a watch component.
