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

Reference 178384 presents the Datejust 31 in Rolesor — Rolex's proprietary combination of Oystersteel and 18ct yellow gold — with a 46-diamond bezel setting that elevates the piece into gem-set territory while retaining the case architecture and movement specification of the standard Datejust family. At 31 mm, the proportions are considered: substantial enough for clear legibility, refined enough to sit elegantly on smaller wrists.

Calibre 2235 powers this reference — the predecessor to the current 2236, fitted to earlier Datejust 31 production before the movement update that introduced the Syloxi hairspring. Both movements achieve COSC chronometer certification and offer Rolex's characteristic finishing standards; the 2235 has a proven service record spanning decades of production and remains fully supported by Rolex's service network. The combination of a steel and gold Rolesor case with a 46-stone diamond bezel introduces a visual richness typical of Rolex's mid-tier gem-set references — spectacular in hand without reaching the stratospheric pricing of all-precious-metal configurations.

The silver index dial provides a clean, legible ground that allows the diamond bezel to command attention without creating tonal competition. This is a watch suited to collectors seeking genuine diamond presence in a Datejust of proven wearability — one that transitions naturally between professional and social environments. The Rolesor two-tone construction also broadens compatibility with mixed-metal jewellery, a practical consideration for buyers who plan to wear the watch daily. Pre-owned examples of the 178384 are consistently sought after in collector circles.
