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

Few dial treatments speak of classical watchmaking refinement as eloquently as Roman numerals on a crisp white ground, and Reference 178273 embodies that tradition with characteristic Rolex precision. The 31 mm Oystersteel case is complemented by an 18 ct yellow gold fluted bezel — the hallmark Rolesor two-tone combination that has defined the Datejust's visual identity across seven decades of production.

The white dial features applied Roman numeral hour markers rendered with immaculate depth and definition, their lacquered surfaces offering sharp contrast against the bright dial ground. A Cyclops lens at the three o'clock position magnifies the date aperture twofold for effortless readability, while the sapphire crystal's double anti-reflective coating eliminates glare. The Jubilee bracelet — a five-piece link design introduced on the original Datejust in 1945 — completes the reference with its characteristic suppleness and dressy character.

Calibre 2235 drives this reference, a self-winding movement produced entirely within Rolex's manufacture and offering the Parachrom hairspring's renowned magnetic and shock resistance. The oscillator beats at 28,800 vph for smooth seconds hand motion, while an instantaneous date mechanism with rapid-setting function allows the wearer to advance the date without altering the time display — a convenience that belies its underlying mechanical elegance. Water resistance to 100 metres confirms the Oyster case's perennial readiness for daily life.
