Rolex Day-Date White Gold — Black Index Dial | Ref. 228349RBR

Among the most commanding expressions of the Day-Date 40, reference 228349RBR pairs an 18-carat white gold case with a crisp black dial and applied index hour markers illuminated by Rolex's proprietary Chromalight compound. The fluted bezel surround is pavé-set with 48 brilliant-cut diamonds, lending an unmistakable brilliance that is never ostentatious — a balance that only Rolex's in-house gem-setting atelier reliably achieves. At 40 mm, the case commands the wrist with architectural confidence while remaining firmly within the vocabulary of dressed horology.

Powering this President is Calibre 3255, Rolex's ninth-generation self-winding movement and arguably the most significant advance in the manufacture's movement architecture in decades. The 3255 incorporates the Chronergy escapement — a redesigned lever-and-escape-wheel pairing that delivers roughly 15 percent greater energy efficiency over its predecessor — alongside a variable-inertia balance wheel controlled by a spirograde regulating spring. The result is a certified Superlative Chronometer rating: ±2 seconds per day in all five positions, well beyond COSC specification. Power reserve extends to approximately 70 hours, accommodating a long weekend without winding.

The President bracelet in 18-carat white gold completes the composition, its semi-circular three-piece links polished and satin-finished in alternating planes to catch light in motion. The concealed Crownclasp integrates invisibly beneath the bracelet's underside, preserving the clean arc of white gold around the wrist. Water-resistant to 100 metres via the screw-down Twinlock crown, the 228349RBR is as impervious to casual adversity as it is suited to the company boardroom — a watch that sets the standard for prestige horology at 40 mm.
