About this watch

Powered by Rolex's perpetual, self-winding caliber 2235 movement, this 24mm white gold Datejust 31 demonstrates the manufacture's commitment to precision timekeeping in their smallest professional case size. The reference 178344 represents a sophisticated interpretation of the classic Datejust formula, pairing the warmth of white gold construction with the brilliance of 24 diamonds set into the fluted bezel. Roman numerals rendered against mother-of-pearl create striking legibility while the Oyster bracelet maintains the sporty character that has defined this collection since 1945. This unworn example showcases how Rolex translates their core design language into more intimate proportions without compromising horological integrity.
