Rolex Day-Date 40 Everose Gold — Eisenkiesel Diamond Dial | Ref. 228235

Crafted entirely in Rolex's proprietary 18 ct Everose gold — a rose gold alloy developed in-house to resist fading and maintain its warm blush tone over decades — the Day-Date 40 ref. 228235 represents the pinnacle of Rolex's gem-setting artistry. The Eisenkiesel dial, named for the German word for flint stone, presents a captivating surface of grey-brown mineral whose crystalline texture shifts under changing light, each example rendered unique by nature itself. Diamond indices replace the conventional hour markers, each stone hand-selected for cut, colour, and clarity by Rolex's in-house gemologists, and set with a precision that stands as a benchmark in the industry.

The 40 mm Everose gold case is crowned by a fluted bezel — one of Rolex's most recognisable design signatures, first introduced in the 1920s as a functional winding aid before evolving into an aesthetic hallmark. At the heart of ref. 228235 resides the Calibre 3255, whose 14 patents reflect Rolex's uncompromising commitment to in-house innovation. The bidirectional Perpetual rotor ensures consistent winding whether the wrist is in motion or at rest, while Paraflex shock absorbers and a Chronergy escapement guarantee long-term robustness. A 70-hour power reserve means the watch runs through a full weekend unworn.

Presented complete with box and papers and dated to the 2024 model year, this reference is a contemporary commission from Rolex's Geneva manufactory. The President bracelet in matching Everose gold, exclusively available on Day-Date references, completes an ensemble of singular coherence. For the collector who demands both horological substance and gem-set magnificence, ref. 228235 admits no compromise.
