Rolex Datejust 31 White Rolesor — 24-Diamond Bezel Dark Mother-of-Pearl Roman Dial | Ref. 178344

The Datejust 31 Ref. 178344 occupies an elegant midpoint in Rolex's size spectrum, combining the horological authority of a 31 mm Oyster case with the jewellery sensibility that defines the Rolesor concept. Here, Oystersteel and 18-carat white gold are combined — the steel case and bracelet providing structural robustness and cool tonal coherence, while the white gold domed bezel set with 24 brilliant-cut diamonds introduces a halo of precious stone that elevates the watch into decorative territory.

The star of the composition is the dark mother-of-pearl dial. Cut from the inner shell of the oyster mollusc, no two mother-of-pearl dials are identical; each exhibits its own iridescent pattern of greens, blues, and deep charcoals, making every watch unique at the level of its most visible surface. Roman numerals in gold provide a classical counterpoint to the organic luminosity of the dial, while the Cyclops lens magnifies the date at 3 o'clock with the clarity expected of Rolex's optical standards. Calibre 2235, the movement contemporary to this reference, provides self-winding precision with a Parachrom hairspring and approximately 48 hours of power reserve.

The Oyster bracelet in Oystersteel presents a purposeful complement to the white gold bezel — robust, flat three-piece links terminating in a folding Oysterclasp that ensures security through its dual-lock mechanism. The result is a watch that wears with the ease of a sports-dress piece while carrying the visual refinement of a fine jewellery timepiece. Waterproof to 100 metres, the Ref. 178344 is a compelling example of Rolex's ability to synthesise precious materials and everyday durability.
