Rolex Day-Date 36 Yellow Gold — Champagne Diamond Dial | Ref. 128348RBR

Reference 128348RBR sits at the peak of the current Day-Date 36 collection in 18ct yellow gold with a diamond-set bezel and champagne dial featuring diamond hour markers. Since its introduction in 1956, the Day-Date has been produced exclusively in precious metals — yellow gold, white gold, Everose gold, or platinum — and carries the full day-of-week display at 12 o'clock alongside the date, a complication Rolex has mastered over seven decades.

At its core is Calibre 3255, Rolex's flagship self-winding movement introduced in 2015 after a decade of development. It incorporates a Chronergy escapement — a nickel-phosphorus lever and escape wheel that improves energy efficiency by roughly 15 per cent compared to the prior generation — paired with a Syloxi-inspired geometry delivering 70 hours of power reserve. The movement meets Rolex's Superlative Chronometer standard, certified to ±2 seconds per day after casing. The RBR suffix designates the factory rainbow or diamond bezel, here set with baguette and brilliant-cut diamonds. The President bracelet, available only on Day-Date models, remains the reference point for prestige bracelet design.

The 128xxx generation Day-Date 36 is the current production reference and commands strong secondary market premiums for diamond-dialled examples in full set condition. Champagne diamond dials are among the most consistently requested configurations by high-net-worth buyers seeking a watch that performs as both a precision instrument and a statement of standing.
