Oscillation System Tuning: Watch Balance Wheel Adjustment Techniques

When adjusting a watch, it is very important to adjust the oscillation system correctly. Among them, the most important component is the balance-spring system, because this system provides the power of the mechanical watch. This article will introduce in detail how to adjust the watch balance wheel.

Adjust the balance wheel position of the watch

Before starting the adjustment, you first need to check that the balance wheel is in the correct position. If the balance wheel is not installed correctly, adjustments will be in vain. To ensure that the balance wheel has been assembled correctly, please check the following aspects:

• Whether the pin of the balance wheel is intact.
• Is the balance wheel mounted in the correct position and not above or below other components?
• The balance wheel has been adjusted correctly to remain in the correct position.

Adjusting the position of the balance requires the use of a balance adjuster. This tool helps you easily adjust the position of the balance wheel so that it stays in the correct position.

Adjust the swing of the balance wheel

The swing amplitude of the balance wheel refers to the left and right swing range of the balance wheel when it swings. The correct swing can ensure the accuracy of the watch and help the watch run more stably. The correct swing range is 1° to 6° of the normal oscillation amplitude range.

Adjusting the swing of the balance wheel can be accomplished as follows:

1. Use the balance adjuster to place the balance at its highest point.
2. Observe the swing amplitude after the balance wheel starts to swing. If the swing amplitude is less than 1 degree, use the adjuster to gently adjust the position of the balance wheel until the swing amplitude reaches 1 degree.
3. If the swing is greater than 6 degrees, use the balance adjuster to gently adjust the balance until the swing drops to less than 6 degrees.

Adjust the vibration rate of the balance wheel

Oscillation rate refers to the number of times the balance oscillates per hour. Adjusting the vibration rate can help the watch record time more accurately.

To adjust the vibration rate of the balance wheel, please read the watch operation manual carefully before adjustment to understand the vibration rate range of the watch. A balance adjuster is required when adjusting the vibration rate. Make adjustments as follows:

1. Place the watch on a level surface and make sure the watch is steady and stopped.
2. Use the balance regulator to adjust the position of the balance wheel until the vibration rate of the balance wheel matches the vibration rate range given in the watch operating manual.

Please note that the vibration rate of the balance should only be adjusted slightly, otherwise it may negatively affect the operation of the watch.

reach a verdict

Adjusting the balance wheel position, swing amplitude and vibration rate of a watch is an important step to ensure the accurate operation of the watch. By using a balance regulator correctly and providing your watch with the proper trimming and adjustment, you can ensure that your watch remains in top condition and keeps time accurate.
