Eradicating the Motion from the Watch Case
The method of eradicating the motion from the watch case is essential and requires precision to keep away from damaging the fragile elements. Here is an in depth step-by-step information:
Getting ready the Work Space
Earlier than starting, guarantee you’ve got a clear, well-lit workspace. Collect the mandatory instruments, together with a watchmakers’ screwdriver, tweezers, and a mushy fabric.
Eradicating the Caseback
Determine the kind of caseback your watch has (snap-on, screw-on, or bayonet) and use the suitable instrument to loosen it. For snap-on casebacks, rigorously pry it open utilizing a plastic spudger. For screw-on casebacks, insert the screwdriver into the notches and gently flip counterclockwise. For bayonet casebacks, twist the caseback counterclockwise whereas barely pulling it away from the case.
Finding and Eradicating the Motion Ring
As soon as the caseback is eliminated, find the motion ring, which holds the motion in place. This ring is normally manufactured from steel or plastic and could also be secured by screws or pressure-fit. Use the tweezers to rigorously take away any screws holding the ring in place.
Unseating the Motion
With the motion ring eliminated, the motion is now free to be rigorously lifted out of the watch case. Use the tweezers to softly grasp the sides of the motion and raise it straight up out of the case. Be aware to not disturb any elements or apply extreme drive to stop harm.
Putting in the Motion into the Watch Case
Upon getting the motion out of the case, it is time to begin placing it again in. The method is basically the reverse of what you probably did to take the motion out, however there are some things to bear in mind.
First, be sure that the motion is clear and freed from any mud or particles. Any dust or particles that get contained in the watch could cause issues down the highway, so it is essential to take the time to wash it correctly.
Subsequent, you’ll want to align the motion accurately within the case. The motion ought to match snugly into the case, but it surely should not be too tight or too free. If it is too tight, you might not be capable to shut the case correctly. If it is too free, the motion might transfer round contained in the case, which might trigger issues with the watch’s operation.
As soon as the motion is aligned, you can begin to interchange the screws that maintain it in place. The screws ought to be tightened evenly and securely, however do not overtighten them. Overtightening the screws can harm the motion or the case.
Changing the Washer
Generally, there shall be a washer between the motion and the case. The washer helps to seal the motion and forestall mud and water from getting contained in the watch. If you exchange the motion, be sure that the washer is in place and that it’s correctly seated.

5. **Lubrication pointers:**
| Gasket Form | Grease Kind | Lubrication Method |
|---|---|---|
| Spherical | Artificial grease SL 5422 HP | Apply grease evenly to all the floor of the gasket |
| Omega 8500 | Silicone grease Omega 8500, LTG 2 S | Apply a small quantity of grease to the gasket’s groove |
| Omega 311 | Silicone grease Omega 311, LTG 2 | Apply a skinny layer of grease to the gasket’s sealing floor |
Changing the Caseback Gasket
A caseback gasket varieties a watertight seal between the watch case and the caseback to stop water from coming into the watch. Over time, gaskets can turn into worn or broken, so it is essential to interchange them repeatedly.
To switch the caseback gasket, you will want the next instruments:
- A pair of tweezers
- A watchmaker’s loupe (magnifying glass)
- A toothpick

Consult with your watch’s specs or seek the advice of with a watchmaker for the suitable torque worth. The torque worth can differ relying on the dimensions, materials, and design of the watch.
Begin by tightening the screws in a star sample, steadily rising the torque till it reaches the specified worth. Be certain that the screws are evenly tightened to stop uneven stress on the gasket.
Notice: For those who would not have a torque wrench, it’s important to train warning when tightening the screws by hand. Overtightening can harm the threads, gasket, and even the watch case.
| Screw Measurement | Torque Vary (Nm) |
|---|---|
| 1.4 mm | 0.5 – 0.8 |
| 1.6 mm | 0.8 – 1.0 |
| 2.0 mm | 1.0 – 1.2 |
After the screws have been tightened, recheck the gasket to make sure that it’s correctly seated and freed from any harm.
Strain Testing the Watch Case
As soon as the again is on, the watch must be stress examined to make sure that it’s waterproof. That is accomplished by putting the watch in a stress chamber and subjecting it to a collection of stress cycles. The stress is then launched and the watch is checked for any indicators of water ingress.
The stress testing course of is usually carried out by a watchmaker or jeweler. The gear used varies, however usually consists of a stress chamber, a stress gauge, and a water bathtub.
The watch is positioned within the stress chamber and the lid is sealed. The chamber is then stuffed with water and pressurized to the specified stage. The stress is held for a time period, usually half-hour, after which launched.
The watch is then faraway from the chamber and inspected for any indicators of water ingress. If the watch is waterproof, there ought to be no indicators of water contained in the case. If there may be water contained in the case, the watch might have to be repaired.
The stress testing course of is a vital step in making certain that the watch is waterproof. It’s a comparatively easy course of that may be carried out by a watchmaker or jeweler.
