Rolex Datejust 31 White Rolesor — White Diamond Index Dial | Ref. 178384

The Datejust 31 ref. 178384 in White Rolesor — Rolex's pairing of Oystersteel and 18ct white gold — sets a tone of cool, refined brilliance. The 46-diamond set bezel frames a white dial with diamond hour markers, creating a uniform constellation of light around the dial. White Rolesor is among the more versatile of Rolex's mixed-metal treatments: the steel Oyster case back and bracelet links provide structural robustness, while the white gold fluted bezel and crown lend precious-metal distinction to the overall composition.

Powering this 31 mm Oyster is Calibre 2235, the self-winding in-house movement that has anchored the mid-size Datejust family for decades. Beating at 28,800 vph with a Glucydur balance wheel and Parachrom hairspring, it delivers Superlative Chronometer accuracy rated at -2/+2 seconds per day. The robust Oyster case construction, finished with a screw-down Twinlock crown, provides water resistance to 100 metres — performance credentials that remain impressive for a timepiece of such jewellery-forward intent.

Among diamond-set Datejust 31 references, the all-white aesthetic of the 178384 — white Rolesor construction, diamond bezel, white dial, diamond indices — occupies a particularly sought-after niche. This coherent use of a single tonal palette gives the piece a unified, almost architectural elegance that appeals strongly to collectors who prefer harmony over contrast. Diamond-dial Rolex examples in the 31 mm size have shown robust demand on the secondary market, and the combination of Rolesor construction and factory diamond settings means the piece carries meaningful intrinsic value beyond its horological merits.
