Rolex Day-Date 40 40 mm 228345RBRS Rose Gold/Diamonds Sundust Rolex Day-Date 40 40 mm 228345RBRS Rose…

The Rolex Day-Date has held an unrivaled position at the pinnacle of Swiss watchmaking since its introduction in 1956, when it became the first wristwatch to display both the date and the full day of the week spelled out in a window. Worn by heads of state, presidents, and cultural icons across seven decades, the Day-Date is widely known as the "President's watch" — a title it has earned through its combination of precious-metal cases, exclusive bracelet, and movement craftsmanship. Reference 228345RBRS belongs to the current Day-Date 40 generation, which enlarged the classic case from 36mm to 40mm to satisfy contemporary tastes while retaining every hallmark of the original lineage.

The 40mm case of the 228345RBRS is crafted entirely from 18k rose gold — Rolex's proprietary Everose gold alloy, formulated to resist fading and retain its distinctive warm blush tone over decades of wear. The fluted-profile case and lugs are polished to a mirror finish that amplifies the metal's natural warmth, while the screw-down crown and 100-metre water resistance rating confirm that Rolex's dedication to robustness extends even to its most formal references.

At the heart of the dial is the sundust finish — a softly glowing, golden-amber hue that catches the light with an almost metallic warmth. The dial is fitted with Roman numeral hour markers that reinforce the watch's dressy character, and the day and date apertures at twelve and three o'clock respectively are executed with crisp, legible typography. The combination of sundust against rose gold creates a monochromatic warmth that is simultaneously understated and deeply luxurious.

Surrounding the dial, the bezel is set with a continuous row of round brilliant-cut diamonds. Factory diamond-set bezels on the Day-Date are sourced, graded, and set by Rolex's in-house gem laboratory, ensuring consistency of color, cut, and brilliance across every stone. This level of vertical integration in gem-setting is rare among Swiss manufactures and contributes meaningfully to both the aesthetic and the long-term value of the reference.

The watch is completed by the President bracelet — an exclusive three-piece link design originally created for the Day-Date in 1956 and never offered on any other Rolex model. Its semi-circular links and concealed folding clasp deliver exceptional comfort and a fluid drape on the wrist that is immediately recognizable. Together, the rose gold case, sundust dial, diamond bezel, and President bracelet make reference 228345RBRS one of the most fully realized expressions of what the Day-Date is designed to be.
