Rolex Day-Date 40 Everose Gold — Fluted Bezel Chocolate Bevelled Roman | Ref. 228235

Reference 228235 represents the Day-Date at its most architecturally resolved: the 40 mm case that replaced the 36 mm format in 2015, executed in Everose gold — Rolex's proprietary 18 ct pink gold alloy developed and patented in-house, formulated with a trace platinum content that prevents the fading of the pink hue over decades of wear. The addition of platinum to the alloy matrix stabilises the copper-rich composition against the microscopic surface oxidation that causes conventional rose golds to drift toward orange over time, ensuring that the warm blush of Everose remains precisely calibrated across the lifetime of the watch.

The fluted bezel in Everose gold establishes a warm, glowing border around a chocolate dial displaying the days of the week and date — both rendered in bevelled Roman numerals, a typographic choice that references the classical dial conventions of mid-century Swiss haute horlogerie. The bevelled cut to each Roman character creates a dimensional shadow that reads with clarity at distance while rewarding close inspection with the kind of craft detail normally reserved for pocket watches. A President bracelet in Everose gold completes the precious metal continuity from case to clasp.

At the heart of this reference sits Calibre 3255 — Rolex's current state of the art for the Day-Date, featuring a Chronergy escapement constructed from non-magnetic nickel-phosphorus alloy, a Parachrom hairspring in blue Parachrom alloy, Paraflex shock absorbers, and an optimised barrel geometry that extends the power reserve to 70 hours. The movement achieves Superlative Chronometer certification, meaning each watch is tested by Rolex after casing to a precision of -2/+2 seconds per day — significantly tighter than COSC standards.
