Rolex Datejust 31 Yellow Rolesor — Slate Grey Roman Dial, Fluted Bezel | Ref. 178273

Reference 178273 in Yellow Rolesor offers a compelling chromatic proposition: the cool, sophisticated tone of a slate grey dial set in dialogue with the burnished warmth of an 18K yellow gold fluted bezel and matching accents. The 31mm case, constructed from 904L Oystersteel with yellow gold appointments, carries the Datejust's signature fluted bezel — originally conceived as a functional knurling for case-tightening, subsequently elevated to one of the most recognisable design elements in watchmaking history.

The grey lacquer dial bears Roman numerals in applied yellow gold, maintaining tonal coherence across the full composition while the contrast between the dark ground and bright numerals ensures immediate legibility. Powering the 178273 is Rolex Calibre 2235, an evolution of the 2135 developed for mid-size Datejust references, incorporating a Parachrom Bleu hairspring for superior resistance to magnetic interference and temperature variation. Its architecture reflects Rolex's decades of refinement in movements tailored to this case diameter.

The five-piece Yellow Rolesor Jubilee bracelet, with its alternating steel and gold links, was specifically designed for the Datejust and has accompanied the collection since 1945. Secured by a concealed folding Crownclasp, it imparts a dressy ease to daily wear. Reference 178273 is an exercise in Rolex's ability to extract elegance from contrast — grey and gold, steel and warmth, utility and beauty.
