imagenLast but not least this is good to know…
The outstanding performance of the new Calibre 3255 is the result of the ongoing effort to improve the mechanical wristwatch by research and development on horological components done by Rolex engineers. It is also made possible by the Manufacture’s in-house expertise, covering all processes involved in movement production. This know-how has pushed back the boundaries of production methods in terms of precision and tolerances, leading to enhanced component quality and performance.
For example, through high-precision machining, the thickness of the walls of the barrel has been reduced by 50 per cent, resulting in a more than 10-hour gain in autonomy.
The synthetic ruby pallet stones on the new Chronergy escapement’s pallet fork measure a mere 125 microns, 50 per cent less than those of the previous generation.
A threefold enhancement in the poise of the oscillator balance wheel was made possible thanks to precision manufacturing.
High-technology processes are also used, such as LiGA (micromanufacturing by electroforming) to produce the paramagnetic pallet fork and escape wheel of the new Chronergy escapement.
