Rolex Day-Date 40 Gold — Chocolate Baguette Diamond Dial | Ref. 228345RBR

Reference 228345RBR stands among the most lavish expressions of the Day-Date 40, featuring a chocolate dial set with baguette-cut diamonds in place of conventional hour markers. Introduced with the 40mm Day-Date generation, the 228xxx series brought a larger case footprint and the current-generation movement to Rolex's flagship dress watch, and this diamond-set variant represents its most opulent configuration.

The watch runs on Calibre 3255, Rolex's benchmark self-winding movement boasting a 70-hour power reserve, Chronergy escapement, and 14 patents. Constructed entirely in 18ct gold — the specific alloy inferred from the 228345 reference prefix — the case presents the signature Day-Date fluted bezel and crown-engraved clasp on the President bracelet. The chocolate dial's baguette diamond hour markers are individually set in yellow or Everose gold mounts, requiring meticulous hand-setting that substantially increases both production time and intrinsic value.

Baguette-dial Day-Date 40 references command notable premiums on the secondary market, driven by limited production numbers and the complexity of their stone-setting. Chocolate dials, in particular, have seen surging collector interest over the past decade as brown and warm-toned dials have moved from niche to highly sought-after. The 228345RBR is a statement piece for the serious collector or discerning wearer who demands the full expression of Rolex's jewellery-making capabilities within a high-complication timepiece.
