Rolex Day-Date 40 Everose Gold & Diamonds — Slate Ombré Dial | Ref. 228345RBR

Reference 228345RBR represents the Day-Date 40 at its most flamboyant — an 18-carat Everose gold case set with a factory diamond bezel, paired with a slate ombré dial that graduates in tone from deep charcoal at the periphery to a lighter centre. Everose is Rolex's proprietary rose gold alloy, formulated to resist the fading that can affect conventional rose gold over time. The 40 mm President case diameter, introduced in 2015 to modernise the historic Day-Date, gives the watch genuine contemporary wrist presence while retaining the full-day display at 12 o'clock.

The movement inside is the Calibre 3255, Rolex's flagship manufacture calibre underpinning the entire current Day-Date line. With 14 patents associated with its design, the 3255 sets benchmarks for precision (±2 s/day Superlative Chronometer), shock resistance, and power reserve at 70 hours — approximately three times the original movements it superseded. The diamond-set bezel on the RBR variant uses brilliant-cut stones set by Rolex's own gem-setting atelier, and the Everose President bracelet completes the ensemble with exceptional wrist comfort through its three-piece curved links.

The 228345RBR occupies the upper tier of Day-Date 40 pricing due to the combination of Everose gold, factory diamonds, and a more unusual ombré dial. Slate dials have attracted collector interest in recent years for their versatility — dressing up with a suit or reading as sophisticated against casual attire. Full set 2024-model examples in Everose gold with diamond bezels carry long waiting times at authorised dealers, reinforcing secondary market premiums. This is a watch for the serious connoisseur who wants maximum Rolex specification in one reference.
