Rolex Day Date 41mm

Introducing the new generation of one of Rolex’s most illustrious model, the Oyster Perpetual Day-Date, now designated: “Rolex Day-Date 40” to highlight its slimmer 40mm case size. It presents a smoother design with a new standard in chronometric performance in the shape of mechanical movement, caliber 3255. The “Rolex Day-Date 40” is the official update to the officially called “Oyster Perpetual Day-Date”.

The original version was launched back in 1956 and at the time was the first waterproof and self-winding chronometer wristwatch to feature a calendar with instantaneous day display. The superb reliability, precision and legibility transformed this watch into an ageless status symbol. Worn by many presidents and people in high-office bestowed it the reputable nickname: “Presidents’ watch”, as well as, its emblematic President bracelet, which Rolex exclusively returns to in this update.

It now reappears with a modernized look and replaces the 41mm case with a 40mm case. In essence they took 1mm from the case and dispersed it along the lugs and middle case giving the watch a more consistent and even flow feel. Thus pairing the diameter of the Day-Date to those more informal models, such as the: Daytona, GMT-Master II and Submariner.

The “Rolex Day-Date 40” introduces a range of new dials. Thin, laser-etched motifs are applied to a traditional sunray finish for a notably sophisticated effect.
The roman numerals are crafted in a deconstructed manner, with numerous hand-applied elements forming the individual numerals. The expertise in craftsmanship showcase Rolex’s artistry which they’ve rendered exclusive to this new Day-Date.

A bracelet as recognizable on the wrist as the President bracelet with its three semi-circular links has clearly made it a trademark and essential feature on this model. First introduced in 1956 and as iconic and extensively replicated by others, as the unique way to exhibit date and day and other features this quintessential Day-Date model standard beholds. Still an update requires embezzlement’s and ceramic inserts inside the bracelet links have been implemented to reinforce durability and compliance.


Rolex made the 41mm a 40mm by taking 1mm from the case and adding it to the bracelet.

Rolex took the opportunity to introduce a new-generation movement, caliber 3255, entirely developed and manufactured by their own horologists to insure an outstanding level of performance. They claim the new movement is twice as exact as those for a chronometer officially certified by COSC. Backing up these statements with 14 patents, which explain the gains in: precision, shock resistance, magnetism and power reserve.

The traditional “Swiss Lever Escapement” always suffered from low efficiency, relaying to the oscillator nearly a third of the energy it receives from the mainspring via the gear train. The new patented “Rolex Chronergy Escapement” improves the efficiency of this key component by 15 per cent. Half of the increased power reserve of caliber 3255 (from 35 to 70 hours in this version) can be attributed to the escapement itself. Nonetheless Rolex will continue to submit all its uncased movements for official COSC certification test and re-test the assembled watches in-house by Rolex for the twice as rigorous precision the new calibers have been designed to preserve.
