Rolex Datejust 31 Rolesor — White Dial, Diamond Bezel & Purple Diamond Roman Numerals | Ref. 178384

Reference 178384 is one of the most jewellery-forward expressions in the 31 mm Datejust family, combining the Rolesor construction — a pairing of Oystersteel and precious gold — with a 46-diamond bezel, a white dial, and purple diamond-set Roman numerals at VI and selected positions. This is not a watch that aims for horological subtlety; it is a statement piece designed for clients whose taste runs toward the intersection of high jewellery and Swiss precision watchmaking.

The Datejust 31 is driven by Calibre 2235, a self-winding movement featuring a Glucydur beryllium alloy balance wheel and Parachrom hairspring, regulated to Superlative Chronometer standards. The Rolesor case pairs the durability of 904L Oystersteel on the case body with 18-carat gold on the crown, bezel setting, and bracelet centre links. The 46-diamond bezel, set in precious metal, frames a dial whose purple diamond markers provide extraordinary colour contrast against the white base. The Jubilee bracelet — five-piece, with its refined middle links — is the natural pairing for this configuration.

This reference occupies the upper tier of the mid-size Datejust segment, targeting clients who want meaningful gemstone integration without committing to a full Lady-Datejust or Pearlmaster. The purple diamond numerals are a relatively unusual configuration in the 178xxx generation, making complete examples in excellent condition particularly desirable. For collectors, the Rolesor construction anchors the watch in Rolex's long tradition of combining materials — a design language dating to the 1930s — while the diamond elements ensure lasting ornamental appeal.
