Rolex Datejust 31 Yellow Rolesor — Slate Grey Roman Dial | Ref. 178243

The Datejust 31 in reference 178243 exemplifies Rolex's Yellow Rolesor aesthetic — a studied contrast of 904L stainless steel and 18-karat yellow gold that has defined the Datejust collection since Rolesor was trademarked in the 1930s. The 31 mm Oyster case carries an 18-karat yellow gold domed bezel that frames a slate grey dial of considerable sophistication; against this cool, mineral ground, raised Roman numerals render a classical legibility befitting both formal and smart-casual contexts.

The Jubilee bracelet — five-piece links in the characteristic alternating steel-and-gold configuration — provides both visual elegance and ergonomic flexibility. The bracelet closes with Rolex's concealed folding Oysterclasp, integrating seamlessly into the bracelet's profile. Inside, the Calibre 2235 self-winding movement governs timekeeping with a 48-hour power reserve and precision-adjusted performance across five positions.

At 31 mm, this is a mid-size expression of the Datejust that bridges the Lady-Datejust and the full 36 mm models, making it a versatile choice for collectors who favour a refined wrist presence. The slate grey Roman dial, rarely seen in this combination with Yellow Rolesor, elevates the reference above standard configurations and marks it as a particularly distinguished piece in the Datejust 31 canon.
