The Rolex Day-Date 40 was introduced in 2016 as a replacement for the -relatively- short-lived Day Date II. Compared to the latter, its proportions appear more refined, while the dimensions are only subtly updated. Inside is Rolex' caliber 3255 self-winding movement. As always, it is available in a great number of configurations. Reference 228345rbr has an 'Everose' rose gold case with diamond-set bezel.


Rolex caliber 3255 Calibre 3255’s criteria for precision in everyday wear are twice as exacting as those for an officially certified chronometer. It incorporates the new Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel‑phosphorus, it is also insensitive to magnetic interference. The oscillator, the true heart of the watch, has an optimized blue Parachrom hairspring, which is also up to 10 times more precise than a traditional hairspring in case of shocks. Thanks to a new barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3255 extends to three days. This means the watch will easily continue to run from Friday evening into Monday afternoon even if not worn or wound.
