Rolex Datejust 31 White Rolesor — 46-Diamond Bezel MOP Diamond Roman VI Dial | Ref. 178384

Reference 178384 exemplifies the Datejust 31 at its most jewellery-forward — a White Rolesor case construction pairing Oystersteel with 18 ct white gold, topped by a 46-diamond bezel and a mother-of-pearl dial set with diamond hour markers and a distinctive Roman VI index. The Rolesor material strategy, which Rolex has employed since the 1930s, creates a two-tone visual rhythm that feels simultaneously sporty and luxurious, while the all-white metal palette of the steel and white gold combination lends this reference a cooler, more contemporary tone than its yellow or Everose Rolesor counterparts.

Calibre 2235 powers the 178384, a 31 mm movement purpose-built for this case size. Running at 28,800 vph with a Parachrom hairspring and automatic winding, it offers a power reserve of approximately 48 hours and the reliability expected of any Superlative Chronometer-rated calibre. The mother-of-pearl dial is sourced from natural shell material, meaning no two dials are precisely identical — the organic patterning of nacre provides a depth and movement impossible to achieve with synthetic materials. The 46-diamond bezel and diamond indices represent significant additional value in gem materials alone.

For collectors and buyers focused on the Datejust 31 as a wearable jewellery piece, the 178384 in White Rolesor with diamond bezel and MOP dial offers a compelling combination of brand equity and gemological substance. This variant trades at a premium over plain-dial equivalents but remains more accessible than full-gold references, making it an attractive proposition for buyers who want visible luxury without committing to an all-gold case. Pre-owned availability is reasonable, though specific dial configurations with Roman numeral markers are less common.
