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

Reference 178344 in its White Rolesor, 24-diamond bezel configuration represents the older-generation Datejust 31 — produced under the 178xxx series before the 2018 update brought the 278xxx generation. White Rolesor combines Oystersteel with 18-carat white gold, the latter used for the bezel, crown, and bracelet centre links, creating a cooler, silver-toned aesthetic that pairs naturally with the pink diamond dial. The 24-diamond bezel, set in white gold with brilliant-cut stones, frames the dial with measured brilliance rather than full pavé excess — restrained by gem-set standards, but unmistakably precious.

Inside, Calibre 2235 — the movement used in pre-2018 31mm Datejusts — provides automatic winding with a Parachrom hairspring for magnetic and shock resistance. While not the silicon Syloxi found in the current Calibre 2236, the Parachrom hairspring remains an advanced component offering notably better magnetic resistance than conventional alloy springs. The Oyster bracelet in White Rolesor provides a secure, practical wear experience with the Crownclasp, complementing the dressy dial configuration with understated construction.

The 178344 generation attracts collectors who appreciate the slightly more restrained proportions of the older 31mm case, as well as those who entered the Datejust market before the 2018 redesign and seek references consistent with their existing collection. Pink diamond dials are among Rolex's most refined dial expressions — the combination of coloured stone and precious metal creates a cohesive warmth. For buyers, the pre-update generation often represents better value entry into a gem-set Datejust than equivalent current-generation references.
