Rolex Day-Date 40 Yellow Gold — White MOP Diamond-Set Dial, Diamond Bezel | Ref. 228348RBR

Ref. 228348RBR occupies the summit of the Day-Date 40 catalogue: an 18 ct yellow gold case paired with a diamond-set bezel, a white mother-of-pearl dial set with diamond indices, and the iconic President bracelet—all crafted in the same warm yellow gold. The 'RBR' suffix in the reference denotes a bracelet set with brilliant-cut diamonds along the centre links, transforming the entire watch into a contiguous field of gold and gemstones. Mother-of-pearl dials are cut from natural bivalve shells, meaning no two dials are identical in their surface patterning; the diamond-set indices sit proud of this organic ground layer.

Calibre 3255 is the movement Rolex selected for the Day-Date 40, a logical pairing given that this is Rolex's most technically advanced calibre. The 3255 delivers a 70-hour power reserve via an optimised barrel with reduced mainspring friction, operates through the Chronergy escapement at 28,800 vph, and drives the Day-Date's signature dual-complication display—the day shown in full at 12 o'clock and the date at 3. With full box and papers and a 2024 production year, this example is effectively new-old-stock in terms of documentation completeness.

A diamond-bracelet Day-Date 40 in yellow gold represents one of the highest-specification configurations Rolex produces in its presidential range. The combination of gem-set bracelet, diamond bezel, and stone-set dial means that this reference requires gemological as well as horological appraisal. For collectors commissioning a single watch that functions simultaneously as jewellery, status marker, and precision timepiece, 228348RBR is among the most complete single-object answers the market can offer.
