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

Reference 178384 is a Datejust 31 in White Rolesor — Rolex's combination of Oystersteel and 18ct white gold — presenting a 46-diamond bezel alongside a blue dial set with applied index hour markers. This configuration sits in Rolex's gem-set tier for the mid-size Datejust, where the addition of a full diamond bezel transforms an already elegant daily watch into a piece of wearable jewellery with genuine horological substance.

White Rolesor applies 18ct white gold to the bezel, crown, and bracelet centre links, creating a uniformly cool, silver-toned appearance that harmonises naturally with the diamond bezel setting. The 46 brilliant-cut diamonds are individually matched for colour and clarity, set in a continuous girdle that encircles the dial without interruption. The blue dial — a colour that reads differently across lighting conditions, from near-black indoors to vivid cobalt in natural light — carries clean applied index markers, balancing the gem-set surround with a classically legible centre. Calibre 2235 (or 2236) powers the movement within the 31mm Oyster case.

The 31mm Datejust in White Rolesor with a diamond bezel occupies a specific position in the market: versatile enough for daily wear, jewellery-forward enough for formal occasions, and priced below the equivalent piece in solid gold. Ref. 178384 draws collectors who prioritise elegance and adaptability over horological complexity, and its combination of blue dial with diamond bezel remains among the most visually balanced configurations in the Datejust range.
