Rolex Datejust 31 White Rolesor — 24-Diamond Bezel Black Diamond Dial | Ref. 178344

Among the mid-size Datejust offerings, reference 178344 stands out for its bold contrast: a 24-diamond bezel set in White Rolesor — the signature Rolex combination of Oystersteel and 18 ct white gold — frames a fully diamond-set black dial whose deep colour creates a striking counterpoint to the surrounding brilliance. This 31 mm case size sits comfortably between the Lady-Datejust 28 and the full Datejust 36, making it a popular choice for wearers who want presence without excess.

Calibre 2235 provides the mechanical heart, a movement refined over decades and distinguished by its Parachrom blue hairspring and Microstella regulation system for precise timekeeping. The Oyster case in White Rolesor delivers both aesthetic harmony and structural robustness, with polished and brushed surfaces alternating across the lugs and bracelet links. The twenty-four brilliant-cut diamonds lining the bezel are each hand-selected for consistency of cut and colour, a process Rolex oversees entirely in-house through its dedicated gem-setting workshops.

Reference 178344 appeals to the collector who wants a jewellery watch that remains entirely wearable and horologically credible. The black diamond dial gives it an evening-ready drama that relatively few Datejust variants achieve, while the Rolesor construction keeps acquisition costs meaningfully below comparable full-gold references. On the pre-owned market, examples with full box and papers in excellent condition attract sustained demand from buyers seeking versatile, gemset Rolex pieces.
