Rolex Datejust 31 Everose Rolesor — 24-Diamond Bezel Black Diamond Roman VI Dial | Ref. 178341

Reference 178341 brings together some of the most layered decorative elements available in the 31mm Datejust range: an Everose Rolesor case, a 24-diamond bezel, a black dial set with diamond hour markers, and Roman VI as the sole numeral in place of the six o'clock index. This Roman-VI-only layout is a recurrent Rolex motif on diamond-dialed Datejusts, providing a typographic anchor at the lower half of the dial without interrupting the visual rhythm of the diamond markers elsewhere on the chapter ring. The black dial ground gives maximum contrast to both the diamond markers and the warm Everose gold tones of the case hardware.

Calibre 2235 underpins this reference, consistent with the 178xxx generation of 31mm Datejusts produced before the introduction of Calibre 2236 in the updated 278xxx series. The 2235 features a Parachrom hairspring for magnetic and shock resistance, self-winding via bidirectional rotor, and COSC chronometer certification. Everose gold — Rolex's proprietary 18-carat rose gold alloy formulated to resist fading over time — is used for the bezel and crown, its warm hue chosen deliberately to complement the black dial rather than contrast against it.

Buyers drawn to this reference typically appreciate the way the warm Everose tones and the cool sparkle of the diamonds create a productive tension across the dial and bezel. The black ground makes this a versatile dress watch across a range of evening and formal contexts where lighter dials would blend into the visual environment. On the pre-owned market, diamond-set dials require careful inspection: checking that all stones are present, secure, and undamaged is essential before purchase, particularly for examples that have seen regular wear. The Roman VI detail, meanwhile, is a subtle point of distinction that knowledgeable collectors will recognise immediately.
