Rolex Datejust 31 Yellow Rolesor — White Roman Diamond Bezel Dial | Ref. 178343

Reference 178343 is a Yellow Rolesor Datejust 31 finished with a 24-diamond bezel and a white dial bearing Roman numeral hour markers — a combination that defines the decorative wing of the Datejust 31 family. The Roman numeral configuration has deep roots in Rolex's design history, evoking the classical dial architecture of the brand's mid-century references while being executed with contemporary precision.

Watches in the 178xxx series carry Calibre 2235, Rolex's self-winding manufacture movement for 31 mm cases, providing a 48-hour power reserve and incorporating a Parachrom hairspring for enhanced reliability under magnetic and thermal variation. The Yellow Rolesor case — Oystersteel body with 18ct yellow gold bezel, crown and caseback — delivers the visual warmth of gold at a case weight that remains comfortable for extended wear. The 24-diamond bezel setting requires precise stone matching and hand-finishing, contributing meaningfully to the piece's declared value.

The 178343 appeals to buyers who want the heritage prestige of the Datejust in a fully adorned configuration: Roman dial, diamond bezel, precious metal — without the full weight or price of an all-gold reference. Pre-owned examples in clean condition with documented provenance remain consistently sought after in the boutique and auction segments of the market. The combination of Rolesor warmth, classical dial typography, and gem-set bezel gives this reference enduring cross-generational appeal.
