Securing the again of a watch is a vital step in guaranteeing its performance and defending its delicate inner elements. This delicate process entails cautious precision and a spotlight to element, guaranteeing that the watch is correctly sealed and shielded from exterior parts. Whether or not you are a seasoned watch fanatic or a novice trying to revive a prized timepiece, understanding the intricacies of this course of is important. On this complete information, we are going to delve into the meticulous steps concerned, offering you with the data and confidence to efficiently put the again on a watch.
Earlier than embarking on this endeavor, it’s crucial to assemble the required instruments and supplies. A watchmaker’s press, or a specialised instrument designed to use even strain, is important for securely closing the watch again. Moreover, a set of watchmaker’s screwdrivers, particularly designed for the tiny screws present in watches, is essential. It’s equally essential to have a clear, well-lit workspace to attenuate the danger of contamination or harm to the watch. With the right instruments and a meticulous strategy, you may confidently proceed with the duty.
The preliminary step is to fastidiously align the watch again with the watch case, guaranteeing that the gasket or O-ring is correctly seated in its groove. The gasket serves as a water resistant seal, stopping moisture from coming into the watch. As soon as aligned, gently press the again onto the case, making use of even strain across the circumference. If the again will not be seated appropriately, it might not shut correctly or compromise the watch’s water resistance.

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 may have a clear, well-lit workspace. Collect the required instruments, together with a watchmakers’ screwdriver, tweezers, and a delicate material.
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, fastidiously 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 fabricated from steel or plastic and could also be secured by screws or pressure-fit. Use the tweezers to fastidiously take away any screws holding the ring in place.
Unseating the Motion
With the motion ring eliminated, the motion is now free to be fastidiously lifted out of the watch case. Use the tweezers to softly grasp the perimeters of the motion and carry it straight up out of the case. Be conscious to not disturb any elements or apply extreme pressure 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, guarantee that the motion is clear and freed from any mud or particles. Any dust or particles that get contained in the watch may cause issues down the street, so it is essential to take the time to scrub it correctly.

Confer 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 scale, materials, and design of the watch.
Begin by tightening the screws in a star sample, step by step growing the torque till it reaches the specified worth. Be certain that the screws are evenly tightened to stop uneven strain on the gasket.
Be aware: When you shouldn’t 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 Dimension | 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.
Stress Testing the Watch Case
As soon as the again is on, the watch must be strain examined to make sure that it’s water resistant. That is accomplished by inserting the watch in a strain chamber and subjecting it to a sequence of strain cycles. The strain is then launched and the watch is checked for any indicators of water ingress.
The strain testing course of is often performed by a watchmaker or jeweler. The tools used varies, however usually consists of a strain chamber, a strain gauge, and a water tub.
The watch is positioned within the strain chamber and the lid is sealed. The chamber is then crammed with water and pressurized to the specified stage. The strain 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 water resistant, there ought to be no indicators of water contained in the case. If there may be water contained in the case, the watch could should be repaired.
The strain testing course of is a crucial step in guaranteeing that the watch is water resistant. It’s a comparatively easy course of that may be carried out by a watchmaker or jeweler.

Sprucing and Inspecting the Watch CaseWhen sprucing the watch case, it is very important use a delicate material and a gentle abrasive to keep away from scratching the floor. The case could be polished utilizing a round movement, and it is very important keep away from making use of an excessive amount of strain. As soon as the case is polished, it ought to be inspected for any scratches or dents. If any scratches or dents are discovered, they are often eliminated utilizing a jeweler’s file or a sprucing wheel. Inspecting the Watch Case Earlier than reassembling the watch, it is very important examine the case for any harm. This consists of checking for scratches, dents, or cracks. If any harm is discovered, it is very important restore it earlier than reassembling the watch. The next desk offers a listing of frequent sorts of harm and find out how to restore them:
Ideas for Guaranteeing a Correct MatchSecuring the again of your watch is important to keep up its performance and aesthetics. Here is a complete information to make sure a correct match: 1. Clear the Surfaces: Use a delicate material or cleansing resolution to take away any dust or particles from each the watch case and again. It will assist stop grit from getting trapped inside. 2. Align the Gaskets: Most watch backs have rubber or silicone gaskets that create a water-proof seal. Be certain that the gaskets are correctly seated of their grooves on the case and again. 3. Test the Again Sort: Completely different watches have various kinds of backs. Determine the kind of again you may have (snap-on, screw-down, or press-fit) to make use of the suitable instruments. 4. Use the Proper Instruments: For screw-down backs, you may want a particular wristwatch case wrench. For snap-on backs, a case knife or watchmaker’s knife is appropriate. For press-fit backs, a watchmaker’s press is beneficial. 5. Place the Again: Rigorously align the again with the case and press it down gently. Keep away from extreme pressure, as this may harm the watch or void its guarantee. 6. Tighten the Screws (If Relevant): For screw-down backs, use a wrench to tighten the screws evenly. Apply reasonable strain to keep away from overtightening. 7. Test the Gasket’s Match: As soon as the again is tightened, frivolously faucet round its edges to make sure the gasket is correctly compressed.
