Rolex Datejust 31 Everose Rolesor — Mother-of-Pearl Diamond Roman Dial Diamond Bezel | Ref. 178341

Reference 178341 combines multiple layers of Rolex's jewellery watch craft into a single 31 mm expression: an Everose Rolesor case, a 24-diamond bezel, and a mother-of-pearl dial set with diamonds and Roman numerals — the VI index rendered as a Roman applied numeral within a field of pavé diamonds. Mother-of-pearl dials carry a long tradition in Rolex's mid-size and ladies' references, prized for the natural iridescence and unique pattern variation each dial exhibits, since no two pieces of nacre are optically identical.

Calibre 2235 is the movement at the heart of the 178341 — a reliable automatic calibre purpose-built for the 31 mm Datejust format. Everose Rolesor construction uses Rolex's proprietary 18k Everose gold alloy, developed in-house for its resistance to colour fading over decades, combined with Oystersteel for the case body and outer bracelet components. The 24-diamond bezel adds a continuous circuit of brilliant-cut stones to the case perimeter. The mother-of-pearl dial, further set with diamond indices and a Roman VI numeral, represents Rolex's integrated approach to gem-setting — the stones and dial material are treated as a unified compositional surface rather than separately applied elements. The Jubilee bracelet in Everose Rolesor provides the characteristic five-link wearing comfort.

On the secondary market, Everose Rolesor Datejust 31 references with diamond bezels and mother-of-pearl dials occupy the upper tier of the 31 mm category. The 178341, as a 178xxx generation reference, has been succeeded by the 278xxx series with Calibre 2236, which may benefit buyers seeking this specification at below-current-production pricing. The enduring appeal of nacre dials ensures sustained collector interest.
