Summarize the transistor balance wheel watch is to dry the battery as the energy, use the transistor as the switch, the balance spring is oscillatory system. Features 1, with mechanical balance wheel system 2, the use of transistors as a switch 3, no mechanical contact principle As we have seen, it comes with a mechanical balance wheel system, the above actually placed coil and magnet, when the balance wheel When rotating, it will cut the magnetic field of the magnet to produce different current frequency and transmit it to the transistor through the coil. Because the transistor itself can realize the switching function through different current direction and frequency, the balance wheel, the coil, the magnet and the transistor together form The oscillating system of the movement, whose frequency is still provided with a balance wheel, is replaced by a transistor that replaces the escapement in the mechanical watch, while a dry battery provides rotational energy to the balance wheel system. History The system was originally invented and patented by Etablissements Leon Hatot (ATO) in the 1950s, and by the 1960s Omega had tried to apply the transistor to its watch but did not end up in the market and ended in failure . Citizen introduced the X-8 electronic transistor movement in 1967, leading the Seiko 3100 movement introduced by Seiko in 1968/1969, making it one of the first brands in the world to bring such watches to market.
