Rolex Day-Date 36 Gold — Pearl Diamond Dial, Diamond Bezel | Ref. 128345RBR

Reference 128345RBR represents the Day-Date 36 in its most jewel-intensive current configuration: a pearl diamond dial paired with a factory diamond-set bezel, presented in 18-carat gold on the President bracelet. The Day-Date's standing as Rolex's prestige reference has been unassailable since 1956, when it became the first wristwatch to display the day of the week spelled out in full. The 128345RBR continues that lineage with maximum gem expression.

Power is provided by Calibre 3255, Rolex's flagship automatic movement and the current standard for the Day-Date 36 and 40 families. It delivers a 70-hour power reserve, runs at 28,800 vph, and incorporates 14 patents including the Chronergy escapement and Parachrom hairspring. The President bracelet in matching gold remains the definitive accompaniment to the Day-Date — a three-link design introduced alongside the reference in the 1950s that has never been offered on any other Rolex model.

Diamond-dial Day-Date references with RBR designation (factory diamond bezel) represent the top tier of the President segment. The pearl dial provides a luminous, iridescent base that reacts dramatically to light, distinguishing it from lacquer or metallic alternatives. Serious collectors understand that factory gem integrity — particularly the matching of diamond grades across dial and bezel — is essential to long-term value preservation.
