Mechanical watch time-travel error is caused by the role of gravity, and the factory adjustment of the movement, personal wearing habits, changes in ambient temperature, the movement of the material, the quality of oil and other objective conditions will increase or Reduce the impact of gravity on the accuracy of travel time. The world is not completely accurate mechanical watch, mechanical watch accuracy can not be compared with the quartz watch. Some friends say that their mechanical watch mechanical watch in a period of time can not minute or error is very small, which is actually a day different wearing position offset by positive and negative results. Judge the quality of a piece of good or bad should be based on the stability of its time, and should not be excessive pursuit of zero error.
Due to the structural characteristics of the spring, friction between materials and the ring and fatigue, the output torque from strong to weak changes, as well as the spring and gears in the transmission distance generated when the friction and so on, will affect the accuracy of travel time. Another climate, regional environment and location also affect the normal operation of clockwork. Now mechanical quartz watch, to overcome the weakness of the mechanical watch, the use of quartz crystal extremely stable high-frequency vibration as a benchmark time, divided by the frequency divider circuit into once per second, and then through the micro-stepper motor or Scanning drive gear, the pointer, indicating time, even so, but the use of quartz crystal by temperature interference, there will be errors, the general daily speed of 15 seconds. This is allowed.
To reduce errors, first of all, place the mechanical watch where the temperature must be appropriate, not too high or too low. Second, the mechanical watch as far as possible without moving the watch or less, but also to avoid the big vibration. If you do not have it, you should take it lightly. Third, timing on the footworker.
