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

Reference 178384 offers one of the most textured dial experiences in the Datejust 31 line-up: a blue concentric circle dial with Arabic numeral hour markers, set beneath a 46-diamond bezel in White Rolesor. The concentric circle pattern — rings of fine grooves radiating from the dial centre — creates a visual depth that shifts with the angle of light, giving this relatively compact watch a remarkable surface complexity. Arabic numerals add a graphic directness that contrasts with the more common Roman or baton alternatives, lending this reference a distinctly individualistic character.

Calibre 2235 drives reference 178384, the self-winding in-house movement that served the Datejust 31 platform before the introduction of the current Calibre 2236. It features a Parachrom blue hairspring for anti-magnetic and anti-shock performance, and a Perpetual bidirectional rotor that ensures efficient winding across a full range of wrist movements. The White Rolesor construction — Oystersteel mid-case with 18-carat white gold applied to the bezel, crown, and bracelet centre links — provides the cool, versatile tone that has made this metal combination a consistent best-seller across the Datejust range.

On the pre-owned market, the 178384 stands out for its uncommon dial configuration: blue concentric circles combined with Arabic numerals appear with lower frequency than standard dial treatments, making this reference appealing to buyers who seek a Datejust 31 with personality beyond the mainstream. The 46-diamond bezel adds jewellery value without compromising the watch's versatility as an everyday piece.
