Rolex Datejust White Rolesor — Mother-Of-Pearl Roman Dial | Ref. 178384

Reference 178384 represents one of the most jewellery-forward expressions within the Datejust 31 collection, pairing Oystersteel with 18 ct white gold in Rolex's signature White Rolesor construction. The case measures 31 mm, a size that occupies the middle ground between the Lady-Datejust 28 and the Datejust 36, lending the watch a refined wearability suited equally to formal and everyday contexts. The bezel is set with 46 brilliant-cut diamonds, a configuration that frames the dial with continuous scintillation without overwhelming the architectural precision of the Oyster case.

The mother-of-pearl dial, finished with Roman numerals, exploits the natural iridescence of the shell to create a luminous surface whose depth shifts subtly with changing light conditions. Powering the watch is the Calibre 2236, Rolex's dedicated movement for the 31 mm Datejust family, incorporating the Syloxi hairspring — a silicon component offering superior resistance to magnetic fields and thermal variation compared with traditional metallic alternatives. The movement delivers a 55-hour power reserve and beats at 28,800 vph, with the Paraflex shock absorber further safeguarding precision under everyday wear.

Completing the configuration is the Jubilee bracelet, a five-piece link design first introduced in 1945 alongside the original Datejust and widely regarded as one of the most elegant bracelets in horology. The combination of a diamond-set bezel, Rolesor case, and mother-of-pearl Roman dial makes this reference a technically accomplished dress watch whose gemological specification is underwritten by the same obsessive engineering standards applied across the professional Rolex range.
