Rolex last year brought in the first homemade Syloxi silicon hair in the 2236 movement and applied it to the Rolex new Datejust pearl lady 34 jewelry watches. In fact, in addition to patek philippe and other brands of the swatch group, Rolex is one of the brands among the first batch of brands that attempted to use the silicon material in wrist watch production. As early as more than a decade ago, Rolex had established cooperation relationship with Swiss electronics and micro technology center (CSEM)  and worked together to the research and development of the project. 

When asked the reason why chose the Syloxi silicon hair in the lady watches, the explanation of Rolex was also very simple: the movements that carried in the men watches were not equipped with silicon hair, but the operation is precise and conforms to requirements.

There are also more high-end timing chronographs with more accuracy in the Basal World in this year. Rolex replica swiss launched the new generation 3255 movement, and this movement is also not equipped with the Syloxi silicon hair,  and what replace it is the  Niobium zirconium alloy blue Parachrom hairspring which has been reimproved.

Stable equilibrium balance wheel is equipped with four gold fine adjustment screws, to make the adjustment process very accurate. Rolex reduce half of the thickness of the clockwork box wall to make full use of inside space more, thus box spring can assembly the clockwork spring with larger capacity, to let the power reserves of the movement increase by more than 10 hours.

Rolex applies the LIGA (lithography, electroforming and injection molding) process to manufacture new Chronergy escapement fork and escapement wheel, and the efficiency of the Swiss lever escapement system is up 15% after being optimized and the power storage also increases to more than 70 hours.
