very early
The use of air, very early in the watchmaking industry has already begun. In the 18th century rolex watches replica , watches technician to control the air resistance to ring the bell by the speed, the technology was later developed into the speed control to ask the preferred method of tapping the table. URWERK inherited this ancient tradition, with the air resistance and further R & D for the control of its rate as a means of automatic winding. Among the UR-202 watches, they used two highly sophisticated micro-turbine (that is, mini air compressor) to replace traditional rotating blades commonly used in the past. The back of the watch can be seen in the two rotating turbine. Tuo two turbines and placed together, according to pre-set position selector switch, the turbine can play a role in absorbing external shock. In daily activities fake swiss watches , the existence of twin-turbo can slow down the dramatic swing Tuo operation, thus reducing gear loss and extend the life of the movement. 3 position selector switch to control the turbine operation, the selective control of outflow from the gas flow inside the watch so that we can affect the air pressure level.
