Rolex, Day-Date 40, 228238, Mother of Pearl Diamond Dial, Yellow Gold, Presidential Bracelet, 40mm

The watch features a 40mm Oyster case crafted from 18ct yellow gold, giving it a broader wrist presence while maintaining the balanced proportions associated with the Day-Date collection.

Its construction follows Rolex’s Oyster architecture, using a screw-down caseback and Twinlock crown system to create a sealed structure rated for water resistance up to 100 meters.

The fluted bezel surrounds the case with sharply machined ridges that redirect light into narrow reflections, creating a more defined outer frame around the dial.

At the center is a white mother-of-pearl dial, formed from natural material rather than synthetic finishing, meaning each dial carries slight variations in texture and reflectivity.

The surface shifts subtly between white, silver, and faint iridescent tones depending on lighting conditions, giving the dial a less uniform appearance than lacquer or sunray finishes.

Diamond hour markers are mounted in yellow-gold settings, creating reflective points that contrast with the softer texture of the mother-of-pearl surface.

The day aperture stretches across 12 o’clock, while the date display at 3 o’clock sits beneath the Cyclops lens, maintaining legibility despite the dial’s reflective character.

Its President bracelet is crafted in matching yellow gold and features semi-circular three-piece links that move fluidly and distribute the watch's weight more evenly across the wrist.

A concealed Crownclasp integrates directly into the bracelet, keeping the fastening system visually hidden when secured.

Powering the watch is the Rolex caliber 3255 automatic movement, featuring a Chronergy escapement and an optimized gear train to enhance efficiency and long-term precision.

The movement delivers approximately 70 hours of power reserve and operates within Rolex’s Superlative Chronometer standard of -2/+2 seconds per day after casing.

The natural irregularity of mother-of-pearl prevents the dial from appearing completely identical under different conditions, making the watch feel more defined by changing light and texture than by a single fixed tone.
