The Rolex Day-Date 40 Ref. 228398TBR in yellow gold with an onyx dial is a striking expression of refined luxury, combining bold natural materials with exceptional gem-setting. This reference elevates the iconic “President’s Watch” into a statement of pure sophistication.
The 40 mm case is crafted from 18k yellow gold and is paired with a baguette-cut diamond bezel, delivering a radiant brilliance that contrasts beautifully with the watch’s clean dial aesthetic. The signature President bracelet completes the look with both comfort and prestige.
The centerpiece is the deep black onyx dial, prized for its perfectly smooth, light-absorbing surface. Free of unnecessary detail, the dial offers a minimalist backdrop that enhances the brilliance of the baguette diamond hour markers.
Maintaining the Day-Date’s classic identity, the dial features the day display at 12 o’clock and a date window at 3 o’clock with the Cyclops magnifier, ensuring both practicality and instant recognition.
Powered by the Rolex Caliber 3255, the movement delivers approximately 70 hours of power reserve along with exceptional precision and reliability. With its fusion of yellow gold, onyx, and diamonds, the Day-Date 228398TBR stands as a bold yet elegant collector’s piece.
