Watch movement model

Model of watch movement: timely movement, mechanical movement, timely mechanical mixed movement, intelligent movement and energy storage movement.

1, exercise in time

The timely movement is the most widely used movement in watches today. It uses quartz crystal oscillator as time reference, with high precision, good stability and moderate price. The frequency of the timing movement is usually 32,768 times per second, but there are also a few high-frequency timing movements, such as bulova's movement with 262 144 times per second and Seiko Hi-Beat 36000 movement. Timekeeping movement can be divided into ordinary timekeeping movement and observatory-level timekeeping movement, and the precision of observatory-level timekeeping movement is higher, and the error range is within 5 seconds per year.

2. Mechanical movement

Mechanical movement is the movement used in traditional mechanical watches. They use mechanical structures to measure and display time. Mechanical movements are divided into manual winding movements and automatic winding movements. Manual winding movement needs to be manually wound, and the internal gear of the movement is driven by the tension of the spring to realize the measurement and display of time. The self-winding movement charges the clockwork through the swing of the watch without manual winding.

3. Timely mechanical mixed movement

Timely mechanical hybrid movement, also known as hybrid movement, combines timely technology with mechanical technology, adopts quartz crystal oscillator to improve accuracy, and adopts mechanical structure to measure and display time. Hybrid movement usually adopts mechanical automatic winding structure, without manual winding.

4. Intelligent sports

With the rise of smart watches, smart movements have been widely used. The intelligent movement has built-in sensors and functional modules, which can realize functions such as short message, telephone call and health monitoring by connecting with smart phones.

5. Power storage movement

Seiko's energy storage movement mainly includes 5R series and 6R series. These movements have long-term energy storage function, which can provide power reserve for days or even weeks.
