THE MOVEMENT
The movement of each Rolex Oyster is designed entirely by a team consisting of experienced engineers and watchmakers.Each movement, from the very first operation carried out on the first component until final assembly performed by the Rolex specialists in Geneva, requires one year’s work.No less then 400 operations are performed on the base-plate of the movement alone.
The movement of an Rolex Oyster comprises more then 220 components.Assembly, for its part, is performed by skilled personnel who patiently build the complex structure of the watch.
The structure basically consists of parts moving in rotation on synthetic jewel bearings that are inserted between the base-plate and special bridges.
However, the production of a Rolex movement does not depend solely on the human eye and hand.Ultra-modern equipment helps the skilled personnel at each stage of production of the movement; design and manufacturing are computer-assisted.
Each stage of manufacturing is under constant control so as to ensure the required level of quality.
THE PERPETUAL ROTOR
In 1931, Rolex invented and patented the very first Perpetual rotor self-winding mechanism.
This consists of a weight which oscillates freely on a central staff, sensitive to the slightest wrist movement.This natural energy is transmitted to the main spring, maintaining it at a constant, equal tension, thus ensuring regular long – term operation.
Once removed from the wrist, after a normal day’s wear, the power reserve build up can ensure operation of the watch for between 40 and 72 hours depending on the model, before it is necessary to perform manual winding.
