Discussion on the adjustment principles of replica watchesmovement

Replica watch movement is very important during adjustment because buyers expect the movement to work perfectly. This article will explore some principles for replica watch movement adjustment to help operators use these movements correctly and ensure their normal operation.

movement cleaning

Before adjustment, the movement needs to be cleaned. During the cleaning process, disassemble the movement and place it in the cleaning solution. Use a fine brush or level washer to clean movement parts. Make sure to clean it thoroughly and there is no residue that will affect the normal operation of the movement.

Manual calibration

Manual calibration is the most basic step in adjusting movement performance and accuracy. Manual calibration is generally divided into the following types:

• Wall clock front - adjusting hour hand
• Wall clock reverse side - adjusting minute hand
• Horizontal - adjust second hand
• Vertical - Adjust vertical error

Adjust the wheels

After manual calibration, the movement's wheels must be adjusted to ensure their accuracy. If the movement is too fast or too slow, the wheel tension and weight can be adjusted to achieve the appropriate speed.

movement coaxiality

Movement coaxiality refers to whether all parts of the movement are on the same axis. This adjustment is key to ensuring that the movement runs smoothly. If it is found that the movement has coaxiality problems, it needs to be readjusted.

Shock absorber adjustment

Adjustment of the movement shock absorber is key to ensuring that the movement remains accurate despite vibrations and external disturbances. By ensuring the correct distance between the shock absorber and the wheel, as well as the tension and elasticity of the shock absorber, you can reduce the risk of problems with your movement.

Precision Testing

After completing all necessary adjustments, accuracy testing is required to ensure the accuracy of the movement. Testing methods include simulating operations at different locations and temperatures and ultrasonic testing.

Replica watch movement adjustment is a critical task, but if you follow the correct steps, you can ensure the accuracy and smooth operation of the movement. This article lists some important principles for movement adjustment of replica watches for users’ reference.
