Tissot quartz watch by internal quartz oscillator to produce a high-precision electrical pulse to drive the stepper motor walk.
The accuracy of the quartz oscillator will not change, so the inherent error of the quartz watch is unchanged.
Battery voltage, external magnetic fields, and violent vibration are the main causes of additional errors. They will usually stop the watch once or twice when you are not paying attention. The cumulative error is significant.
Therefore, avoid contact with strong magnetic field and strong vibration, and check and replace the battery in time if it slows down significantly.
In addition, excessive heat and cold should also be avoided, such as the table in the summer where there is direct sunlight error is too large: if the quartz watch error is too large, beyond the adjustment range of the fine tuning capacitor, you need to adjust the fixed capacitor at the same time.
For a slow quartz watch, you can gradually reduce the capacity of the fixed capacitor and fine tuning capacitor M, until removed.
Generally within 24 hours can be adjusted fast about 20 seconds.
A small capacitor of 5-40 pico can also be strung in the quartz crystal circuit to speed up the travel time.
Quartz watches travel faster, often because the fixed capacitor, fine tuning capacitor off or failure.
The small capacitance of 5-50 skin method should be repaired, and the specific capacity and value should be determined after repeated trial.
The repaired capacitor should be small, high quality factor, high whiskers ceramic capacitor can be used.
