Rolex Datejust 31 Everose Rolesor — Dark Mother-of-Pearl Diamond Dial with 24-Diamond Bezel | Ref. 178341

Reference 178341 balances the warmth of Everose Rolesor construction against the dramatic depth of a dark mother-of-pearl dial, a pairing that achieves a more assertive character than the light or white mother-of-pearl configurations while retaining the organic iridescence that makes shell-based dials uniquely compelling. The 24-factory-set diamond bezel introduces measured brilliance, creating a frame of light around the dark dial that heightens rather than overwhelms its natural surface quality. At 31mm, this reference occupies the Datejust's most versatile case size.

Calibre 2235 drives this 178xxx generation reference, a proven manufacture movement with Parachrom hairspring and Glucydur balance wheel, providing approximately 48 hours of autonomy. The Everose Rolesor construction — Oystersteel combined with 18ct Everose gold — ensures that the warm rose-gold tones of the crown, caseback, and bracelet centre links age predictably over time, as Everose's proprietary alloy formula is specifically engineered to resist the colour fade that affects standard rose gold alloys. The dark mother-of-pearl dial is hand-selected for depth and consistency of colour, with diamond indices set individually at the Rolex gem-setting atelier.

On the collector market, dark mother-of-pearl Datejust references are valued both for their visual distinctiveness and their relative scarcity compared to white or lacquered dial variants. The 178341, combining a 24-diamond bezel with diamond hour markers and a dark organic dial, represents one of the more complete jewellery-watch configurations in the mid-size Datejust range without crossing into full-pavé territory. It is a reference that rewards ownership over time, as dark mother-of-pearl's tonal complexity becomes more apparent with extended familiarity.
