MOA tourbillon process
The tourbillon was a clock speeding device invented by Swiss watchmaker Louis Bauer in 1795. The Tourbillon in French (also known as Tébillon) has a meaning of “whirlpool” and refers to a kind of mechanical watch that is equipped with a “rotating escapement speed governor mechanism”. The tourbillon mechanism is used to correct the error caused by the gravitational force on movements for clocks and watches. The tourbillon represents the highest level in the manufacturing process of the mechanical watch, having the entire escapement speed control mechanism combined together and can rotate. It rotates at a constant speed to minimum the impact of gravitational force on the "escapement system" in the mechanical watch and to improve the accuracy of timing. Due to its unique mode of operation, the dynamic beauty of the watch has reached the peak, and has always been hailed as "the king of the watch".
