Rolex, Day-Date 36, 128238, Mother of Pearl Diamond Dial, Yellow Gold, Presidential Bracelet, 36mm

A 36mm Oyster case in 18ct yellow gold forms the foundation of the watch, combining polished outer surfaces with a dense, solid structure that reinforces its overall weight and presence.

Its architecture includes a screw-down caseback and a Twinlock crown system, creating a sealed environment that maintains water resistance to 100 meters.

Encircling the case is a fluted bezel, cut with sharp, consistent ridges that interact dynamically with light, shifting in intensity as the wrist moves.

The dial is produced from natural white mother-of-pearl, a material formed organically, so no two dials share the same pattern or tone distribution.

Depending on lighting conditions, the surface transitions between soft iridescent hues, giving the watch a constantly changing visual character.

Diamond-set hour markers are positioned across the dial, mounted in gold settings that align precisely to maintain spacing and visual balance without disrupting readability.

The day display at 12 o’clock spans the width of the dial, while the date window at 3 o’clock is magnified through the Cyclops lens, keeping both complications highly legible against the textured surface.

A President bracelet in matching yellow gold completes the watch, featuring semi-circular three-piece links that contour naturally around the wrist rather than sit rigidly.

The concealed Crownclasp ensures that the bracelet closes without visible interruption, preserving a continuous flow from case to clasp.

Internally, the caliber 3255 movement operates with high mechanical efficiency, featuring an optimized escapement and enhanced energy transmission.

With a power reserve of approximately 70 hours and regulated to Rolex’s Superlative Chronometer standard, the movement is engineered for consistent performance over extended periods of wear.

The use of mother-of-pearl introduces an element that cannot be replicated through manufacturing, making the dial less about precision uniformity and more about natural variation within a controlled design.
