One of the releases from Rolex at this years Baselworld was the introduction of a brand new in-house calibre. The Rolex Calibre 3255
When Rolex makes a new movement, they do a thorough job of analyzing every area, to see what improvements can be made. 14 Patents have been filed by Rolex for this movement.

The power reserve of the movement is approximately 70 hours. This is a 24 hour increase (or 50%) more than the previous generation.
Its reliability have been optimized at the level of its overall architecture as well as its individual components, and through the use of high-performance lubricants developed and synthesized in-house. Rolex is the only independent watch manufacturer to develop and synthesize its own lubricants.
One of the key innovations in the movement is the new Rolex Chronergy escapement. The result of extensive research, the geometry of the new escapement improves the efficiency of this key component by 15 per cent. Almost half of the increased power reserve of calibre 3255 can be ascribed to the escapement itself. Made of nickel-phosphorus, the Chronergy escapement is, furthermore, insensitive to magnetic interferences

Space is at a premium inside a watch movement. To increase the capacity of the mainspring in calibre 3255 without increasing the size of the barrel housing , Rolex reduced the thickness of its walls by half. This solution represented a considerable challenge both for machining and for the production process, pushing back the boundaries of current production methods. The resulting gain in space allowed for the accommodation of a mainspring with greater capacity, thereby increasing the movement’s autonomy by more than 10 hours.

The first watch that features the new Calibre 3255 is the new 40mm Day Date released at Baselworld 2015.
