Rolex has just introduced a new-generation mechanical movement, the new Calibre 3255 with 14 patents. The new Rolex boasts a superlative level of chronometric precision, with criteria surpassing those of the Swiss Official Chronometer Testing Institute.
The 3255 combines high energy efficiency with great dependability, and has an oscillator with an optimized blue Parachrom hairspring. The first watch to receive the new Calibre 3255 is the Oyster Perpetual Day-Date 40, which features a modernized design with a 40mm case.
You’ll see in this article that the Day-Date 40 in platinum case has a very attractive, laser-etched blue dial. The enhancement of the Chronergy escapement and Parachrom hairspring modify the geometry to increase the efficiency of escapement by 15%, contributing to almost half of Calibre 3255’s enhanced power reserve.
