Rolex Day-Date Yellow Gold — Fluted Bezel Silver Diamond Dial | Ref. 118238

Reference 118238 represents the Day-Date 36 at its most architecturally traditional: solid 18-carat yellow gold throughout, a fluted bezel machined from the same alloy as the case, and a silver dial set with diamond hour markers. Introduced in the 118xxx series — the penultimate generation of the 36 mm Day-Date before the current 128xxx family — this reference embodies five decades of continuous design logic. The Day-Date remains the only Rolex produced exclusively in precious metals, and the 36 mm diameter that originated the reference in 1956 carries particular historical weight.

Calibre 3155 powers this reference — a self-winding movement specific to the previous-generation Day-Date 36 and distinct from the Calibre 3235 that replaced it in 2015. The 3155 features an instantaneous day and date display, a Glucydur balance wheel, and a Parachrom hairspring introduced during mid-production. Power reserve is approximately 48 hours. While superseded by the more energy-efficient 3235, the 3155 has accumulated decades of reliable service history and remains fully serviceable through the Rolex network. The President bracelet — available only on the Day-Date and Lady-Datejust — is executed in solid yellow gold.

Pre-2015 Day-Date 36 references occupy a compelling position on the secondary market: their prices typically sit below equivalent current-generation 128238 examples while offering near-identical aesthetics, the same precious-metal construction, and the historical prestige of the platform. Collectors focused on value relative to visual impact often gravitate toward the 118xxx series. Diamond-dial variants command a modest premium over index examples, and the fluted bezel — long associated with the Day-Date's authoritative character — remains the most requested bezel choice globally.
