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

The Datejust 31 reference 178384 occupies a distinctive position within Rolex's mid-size lineup, blending the sophistication of Rolesor construction with the visual drama of a 46-diamond set bezel. White Rolesor — Rolex's proprietary combination of Oystersteel and 18-carat white gold — lends the case a cool, harmonious tone that frames the blue Roman dial with understated opulence. The blue dial with Roman numeral indices delivers a classic legibility while the diamond bezel elevates the piece unmistakably into jewellery-watch territory.

Powering the 178384 is the Calibre 2235, Rolex's self-winding manufacture movement engineered specifically for the 31 mm Datejust. It offers approximately 48 hours of power reserve, beats at 28,800 vph, and incorporates the Parachrom hairspring for improved resistance to magnetic fields and thermal shock. The Oyster case, water-resistant to 100 metres, is joined by a Jubilee bracelet — Rolex's most refined link design — whose five-piece construction drapes elegantly on the wrist. The blue dial's sunray finish interacts with light in a way that shifts perception throughout the day.

Collectors gravitating toward the 178384 are typically drawn to gem-set Datejusts that balance wearability with visual impact, without crossing into full pavé territory. The Roman numeral configuration appeals to those who prefer a timeless, almost architectural dial layout. White Rolesor commands a premium over steel-only references while remaining more accessible than solid precious-metal examples. As a discontinued reference — superseded by the 278 series — the 178384 now attracts buyers who appreciate the slightly more compact 31 mm proportions of its generation.
