Rolex Day-Date 36 36 mm 118238SDP Yellow Gold Silver

The Rolex Day-Date is widely regarded as the most prestigious watch in the Rolex collection, and the 36 mm reference 118238SDP embodies everything that has made this model a symbol of achievement since the original Day-Date debuted in 1956. As the first wristwatch to display the day of the week spelled out in full alongside the date, the Day-Date earned its unofficial title of "the President's watch" — a name later cemented by the introduction of the iconic President bracelet on which this very reference is worn. For over six decades the Day-Date has graced the wrists of world leaders, captains of industry, and discerning collectors who understand that true luxury requires no explanation.

At 36 mm, reference 118238SDP occupies the classic Day-Date case diameter — the size in which the model was born and in which it remains most historically correct. The case, crown, and fluted bezel are crafted entirely from 18k yellow gold, Rolex's in-house gold alloy engineered for lasting richness of color and resistance to wear. The fluted bezel is one of the most recognizable signatures in watchmaking: its precise machined grooves catch the light from every angle, amplifying the brilliance of the precious metal and lending the watch an architectural elegance that is impossible to replicate.

The silver dial of the 118238SDP is set with diamonds, elevating what is already a refined surface into a genuine jewel. Rolex diamond-sets its dials in-house, with each stone individually selected for cut, color, and clarity before being secured by Rolex's own gem-setting artisans. The day display, spelled out in full at 12 o'clock, and the date aperture at 3 o'clock are rendered with the crisp legibility that Rolex demands across every reference in its catalog. Together, the diamond markers, polished indices, and warm yellow-gold applied lettering create a dial that rewards close inspection.

Powering the 118238SDP is a Rolex automatic movement, representative of the Caliber family used in the Day-Date 36 generation — a self-winding mechanical movement built, regulated, and certified entirely in-house at Rolex's Geneva manufacture. Rolex submits its movements to certification by COSC, the Swiss Official Chronometer Testing Institute, and then performs its own additional accuracy testing before a watch leaves the manufacture. The result is a movement of exceptional reliability and precision that requires nothing from its owner beyond regular wear to remain wound and running true. With 100 meters (330 feet) of water resistance, the watch also carries a level of robustness appropriate for daily life.

The President bracelet is exclusive to the Day-Date and Lady-Datejust and has been an inseparable part of this reference's identity since the Day-Date's earliest years. Constructed from solid 18k yellow gold links with a semi-circular three-piece link design, the President bracelet is one of the most comfortable and luxurious metal bracelets ever produced. Its hidden Crownclasp ensures a smooth, uninterrupted silhouette on the wrist, while the weight and warmth of solid gold against the skin are unmistakably premium.
