Rolex Datejust 31 White Rolesor — Pink Mother-of-Pearl Diamond Dial, 24-Diamond Bezel | Ref. 178344

Reference 178344 represents Rolex's considered approach to gem-set watchmaking at the 31 mm scale, pairing White Rolesor construction with a pink mother-of-pearl dial set with diamonds. Mother-of-pearl dials are harvested from molluscs, meaning no two are identical — the iridescent, layered surface catches light differently at every angle, producing an organic warmth that no lacquered or metallised dial can replicate. The 24-diamond bezel provides a focused concentration of stones that frames the case without overwhelming it.

The movement within is Calibre 2235, a self-winding manufacture calibre built for Rolex's 31 mm Datejust family. The movement features a Parachrom blue hairspring, Paraflex shock absorbers, and a self-winding Perpetual rotor. Power reserve sits at around 48 hours. The White Rolesor case — combining Oystersteel flanks with 18-carat white gold bezel setting and crown guards — maintains Rolex's Oyster standard of 100-metre water resistance. The Jubilee bracelet, with its characteristic five-piece polished-and-brushed link construction, brings a dressy sensibility appropriate to the watch's overall character.

This reference appeals primarily to collectors and buyers seeking a high jewellery Datejust with genuine gemological substance — the diamond-set dial alongside a diamond bezel creates a multi-layered presentation rarely achieved at this price point in Swiss watchmaking. Pink mother-of-pearl is one of the more sought-after dial variants within the 178344 family, and surviving examples in unworn or lightly worn condition with original bracelet command consistent market interest. Buyers should verify the diamond grading documentation if available, as factory-set gem quality is an important value determinant.
