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

Where reference 178343 leans toward warmth, the 178344 achieves an altogether cooler and more enigmatic chromatic register. The White Rolesor construction — Oystersteel paired with 18-carat white gold — aligns naturally with a 24-diamond domed bezel whose stones appear even more vivid against the cooler metallic ground. The dark mother-of-pearl dial, formed from a single slice of natural nacre, delivers an iridescent surface that shifts in character with every change of lighting — from near-black in shadow to deep blue-grey under direct illumination, each dial unique by virtue of its organic origin.

Roman numeral hour markers are applied directly to the dial, their polished white gold forms contrasting against the dark nacre with precise legibility. The 31 mm case in Oystersteel with Rolex's characteristic case finishing — alternating brushed and polished surfaces — balances the dial's organic drama with mechanical precision. Calibre 2235 provides the self-winding movement architecture, with the Parachrom hairspring and Rolex's proprietary escapement ensuring chronometric accuracy across a broad range of operating conditions.

The Jubilee bracelet — paired here in Oystersteel with 18-carat white gold outer links — completes the White Rolesor theme with its quintessential five-piece link construction. The combination of dark mother-of-pearl, white gold, and diamond creates a watch that occupies the intersection of haute joaillerie and practical horology. A Datejust 31 for those who seek depth and iridescence over uniformity, with full Rolex precision underneath.
