Rolex Day-Date 36 Yellow Gold — White Index Dial, Fluted Bezel | Ref. 118238

Among the older Day-Date 36 references still widely traded, the 118238 in 18-carat yellow gold with fluted bezel and white index dial stands as one of the defining expressions of the model. Introduced as part of the pre-3255 generation, reference 118238 carried the Calibre 3155 — a movement that, while lacking the 70-hour power reserve of its successor, earned a reputation for precision and longevity across decades of service. The all-yellow-gold construction, from case to President bracelet, embodies the Day-Date's original proposition: a watch worn exclusively by heads of state, industry, and the arts.

Calibre 3155 is a self-winding movement with a Glucydur beryllium balance wheel and Microstella regulation, beating at 28,800 vph with a 48-hour power reserve. The fluted bezel, machined from solid yellow gold, is both an aesthetic signature and a functional element — its ridged profile enhancing the case's water resistance in early Rolex engineering logic. The white dial with applied gold hour markers and President bracelet with concealed Crownclasp clasp completes a configuration that has remained essentially unchanged in character for over half a century.

Reference 118238 occupies a sweet spot on the secondary market: well-known enough to command strong liquidity, yet priced below the current 228238 generation, making it an accessible entry point into gold Day-Date ownership. Collectors value it for its proven movement, full-gold construction, and the historical resonance of the 36 mm case size — the original Day-Date proportion before the 40 mm 228xxx series expanded the line.
