Rolex calibre 3255
Baselworld 2015 - At Baselworld, Rolex is introducing calibre 3255, a new-generation mechanical movement that sets new standards of performance for the core characteristics of a watch movement – precision, power reserve, reliability, resistence to shocks and magnetism, as well as the ease and convenience of its adjustment.
A compelling example of avant-garde watchmaking technology, this self-winding mechanical movement is entirely developed and manufactured by Rolex. It is backed by 14 patents and a number of innovative technological solutions relating not only to component design but also to processes involving new technologies that push back the limits.
... Insensitive to magnetic fields, the Parachrom hairspring offers great stability in the face of temperature variations and remains more precise than a traditional hairspring in case of shocks. Also, more than 90 per cent of the movement parts have been redesigned."
Calibre 3255's criteria for precision in everyday wear are twice as exacting as those for an officially certified chronometer. Its superlative accuracy is tested by Rolex after the movement has been cased, using high-technology equipment and an methodology that simulates the conditions in which a watch is actually worn. Its power reserve extends to approximately 70 hours, representing an increase of 50 per cent, compared to that of the previous generation.
The oscillator of calibre 3255 is fitted with a blue Parachrom hairspring, patented and manufactured by Rolex in an exclusive alloy of niobium and zirconium. Insensitive to magnetic fields, the Parachrom hairspring offers great stability in the face of temperature variations and remains more precise than a traditional hairspring in case of shocks. Also, more than 90 per cent of the movement parts have been redesigned.
The result of extensive research, the geometry of the new Rolex Chronergy 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.
Calibre 3255 benefits from new, updated aesthetics, both in the shape and arrangement of the bridges as well as in their meticulous, traditional decoration. The aesthetics have evolved while preserving the characteristic features of Rolex Perpetual movements.
