Rolex Datejust 31 Yellow Rolesor — Fluted Bezel Silver Dial with Diamond Roman Numerals

Among Rolex's mid-size offerings, the 31mm Datejust in Yellow Rolesor occupies a distinctive position — blending the warmth of 18ct yellow gold with the robustness of Oystersteel in a combination that has defined refined everyday elegance for decades. The fluted bezel, one of Rolex's most iconic design signatures, catches light with architectural precision, while the silver dial set with diamond Roman numeral hour markers elevates this reference firmly into the realm of fine jewellery watchmaking.

Rolesor — Rolex's proprietary term for its steel and gold combination — sees yellow gold applied to the bezel, crown, and bracelet centre links, contrasting against polished and brushed Oystersteel flanks. The silver dial carries diamond-set Roman numerals in place of applied indices, each stone individually set and rigorously inspected for cut and clarity. At 31mm, the case houses Calibre 2235 (or 2236 in more recent production), a manufacture movement offering a 55-hour power reserve with Parachrom hairspring and Rolex's characteristic Paraflex shock absorbers for exceptional resilience.

This reference appeals to collectors who seek the intersection of daily wearability and gem-set luxury. The 31mm case threads the needle between the Lady-Datejust 28 and the full 36mm, making it a versatile choice across wrist sizes. Yellow Rolesor Datejusts with diamond Roman numerals retain strong secondary market appeal, particularly in complete sets, owing to their dual identity as both functional timepieces and jewellery-grade accessories.
