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

Reference 178344 configures the Datejust 31 in White Rolesor with a 24-diamond bezel and a mother-of-pearl dial set with diamond hour markers — an arrangement that draws on both the organic iridescence of the dial material and the geometric brilliance of the gem-set case to create a watch of layered visual complexity. Mother-of-pearl dials have been central to Rolex's ladies' and mid-size offerings for decades, each dial unique in its natural colour variation, ranging from warm ivory to cool iridescent blue-white depending on the nacre's origin and orientation.

Calibre 2235, the predecessor to the current 2236, drives this reference — a robust self-winding movement developed specifically for Rolex's mid-size case architecture. The 24-diamond bezel in 18ct white gold provides an even gem-set perimeter around the case, with each brilliant-cut stone selected for matching colour and clarity to ensure visual continuity. The diamond hour markers on the mother-of-pearl dial create a field of light that shifts with movement and ambient illumination, making the watch perpetually dynamic. White Rolesor construction — Oystersteel case with white gold bezel and Jubilee bracelet outer links — offers the classic two-tone aesthetic without full precious metal weight.

For collectors, the 178344 occupies a well-established place in the Datejust hierarchy as a sophisticated mid-size jewellery watch. Mother-of-pearl diamond variants consistently attract buyers seeking maximum decorative effect at the 31mm footprint, and the reference performs reliably in the pre-owned market. Its combination of natural dial material with precision gem-setting reflects Rolex's ability to integrate craft disciplines across a single reference.
