Rolex Datejust 31 Rolesor — Mother-of-Pearl Roman Dial, Diamond Bezel | Ref. 178344

Reference 178344 pairs the 31 mm Datejust case in white Rolesor—a combination of Oystersteel and 18 ct white gold—with a mother-of-pearl dial set with Roman hour markers and enclosed by a 24-diamond bezel. Mother-of-pearl dials have been integral to Rolex's ladies' and mid-size Datejust repertoire for decades, valued for their organic iridescence and the way their surface shifts character under changing light conditions.

The Calibre 2235 movement drives the time and date indication, housed within the 31 mm Rolesor case. White Rolesor configuration means the steel case and bracelet are accented with white gold components—including the fluted or diamond bezel and crown—creating a cohesive cool-toned aesthetic. The 24-diamond bezel setting uses matched brilliant-cut diamonds arranged to maximise brightness and uniformity, while the mother-of-pearl dial surface provides a naturally luminous backdrop for the Roman numeral hour markers. The Jubilee bracelet typical of this reference extends the elegance of the dial treatment through the wrist.

Mid-size Datejust references in Rolesor with mother-of-pearl dials represent a cornerstone of Rolex's jewellery watch segment, offering the brand's quality assurances and factory gem-setting at an accessible price relative to solid gold configurations. The 178344 is a considered choice for wearers who prioritise elegance and Rolex heritage over complications, and its classic construction ensures continued appeal in the pre-owned market.
