Rolex Datejust 31 White Rolesor — 24 Diamond Bezel Meteorite Diamond Dial | Ref. 178344

Reference 178344 in White Rolesor — combining Oystersteel with 18ct white gold bezel, crown, and Jubilee bracelet centre links — presents the Datejust 31 in a configuration of singular rarity: a 24-diamond set bezel paired with a meteorite dial adorned with diamond hour markers. Meteorite, harvested from the Gibeon formation in Namibia and sliced to reveal the characteristic Widmanstätten crystalline pattern formed over billions of years, is among the most extraordinary dial materials in fine watchmaking. No two meteorite dials are identical, making each watch a genuinely singular object.

Powering the 178344 is the Calibre 2235, a self-winding perpetual movement developed by Rolex for the 31mm case diameter. The Cal 2235 beats at 28,800 vph with a Parachrom hairspring, delivers a 48-hour power reserve, and carries COSC chronometer certification. Its compact architecture required Rolex's engineers to maintain the same principles of robustness and precision found in larger calibres while working within the spatial constraints of the mid-size case. The Oyster case achieves 100 metres of water resistance via the Twinlock crown system.

The meteorite dial Datejust occupies a special niche in collector circles — a watch that satisfies horological rigour while offering a dial material that no other brand has used with greater regularity or more successful results than Rolex. The interplay between the silver-grey meteorite, the brilliant-cut diamond bezel, and the cool tones of White Rolesor is uniquely cohesive. Reference 178344 examples with complete documentation and in excellent condition are consistently absorbed quickly on the secondary market, particularly among collectors who prize geological as well as horological provenance.
