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.
