If you’re the proud owner of a watch, you know that keeping it in good condition is essential. This means not only keeping it clean and free of dust, but also ensuring that the back is securely attached. While it may seem like a daunting task, putting the back on a watch is actually quite simple with the right tools and a little bit of patience. In this article, we’ll guide you through the process step-by-step, so you can keep your watch ticking for years to come.
The first thing you’ll need to do is gather the necessary tools. These include a watch case opener, a caseback press, and a pair of tweezers. You can purchase these tools online or at most hardware stores. Once you have your tools, you’re ready to begin the process. First, you’ll need to remove the old back from the watch. To do this, use the watch case opener to pry the back off. Be careful not to damage the watch case or the back itself. Once the back is off, you’ll need to clean the gasket that sits between the back and the case. This gasket helps to keep water out of the watch, so it’s important to make sure it’s clean and in good condition.
Now it’s time to put the new back on the watch. First, apply a thin layer of gasket glue to the gasket. Then, carefully place the back on the watch case and press it into place using the caseback press. Be sure to apply even pressure around the entire circumference of the back. Once the back is on, check to make sure that it’s securely attached. You should not be able to move it around with your fingers. If the back is not securely attached, it could leak water into the watch, so it’s important to make sure that it’s on tight.
Dismantling the Watchband
Before you can remove the back of a watch, you need to detach the watchband. This is a relatively simple process, but it is important to be careful not to damage the watch or the band.
To begin, locate the spring bars that connect the watchband to the watch lugs. These are small, cylindrical pins that are typically made of metal. Once you have located the spring bars, use a spring bar tool, a small screwdriver, or a pair of tweezers to gently push them inward. This will release the watchband from the watch lugs.
If you are having trouble removing the spring bars, you can try using a small amount of force. However, be careful not to use too much force, as this could damage the watch or the band. If you are still having trouble, you can take the watch to a jeweler or watchmaker for assistance.
Here is a table that summarizes the steps for dismantling the watchband:
| Step | Instructions |
|—|—|
| 1 | Locate the spring bars that connect the watchband to the watch lugs. |
| 2 | Use a spring bar tool, a small screwdriver, or a pair of tweezers to gently push the spring bars inward. |
| 3 | Remove the watchband from the watch lugs. |
Once you have removed the watchband, you can proceed to the next step, which is removing the back of the watch.
Preparing the Watch Case
Before you can put the back on a watch, you need to prepare the watch case. This involves cleaning the case and making sure that the gasket is in place.
To clean the watch case, you can use a soft cloth and a mild soap solution. Be sure to rinse the case thoroughly with water and dry it completely before proceeding.
The gasket is a rubber or silicone ring that sits between the watch case and the back of the watch. It helps to keep water and dust out of the watch. If the gasket is damaged or missing, you will need to replace it before you can put the back on the watch.
To check the gasket, simply remove the back of the watch and inspect it. If the gasket is damaged or missing, you will need to replace it. You can purchase a new gasket from a watchmaker or online.
Replacing the Gasket
To replace the gasket, simply place the new gasket in the groove around the watch case. Make sure that the gasket is seated properly and that there are no gaps.
Once the gasket is in place, you can put the back of the watch back on. Be sure to tighten the screws evenly and do not overtighten them.
Aligning the Crystal
Once the movement is secured in the case, it is time to align the crystal. This process requires careful attention to detail to ensure that the crystal is properly seated and protected from damage.
Centering the Crystal
The first step is to center the crystal in the case. To do this, use a soft cloth or tweezers to gently press the crystal into place. Start by aligning the crystal with the bezel and then work your way around, pressing it firmly into the case. Ensure that the crystal is evenly centered and that there are no gaps between the crystal and the case.
Applying Pressure
Once the crystal is centered, apply pressure to secure it in place. You can use your fingers or a soft rubber mallet. Start by gently tapping around the edges of the crystal, gradually increasing the pressure until the crystal is firmly seated. Avoid applying excessive force, as this could damage the crystal or the case.
Checking the Alignment
After the crystal is secured, check its alignment by holding the watch up to a light source. Look for any gaps or unevenness between the crystal and the case. If necessary, make adjustments by gently tapping the crystal until it is properly aligned.
| Additional Tips for Aligning the Crystal: |

Securing the Crystal with the Bezel
4. Inspecting the Bezel
Before securing the bezel, carefully inspect it for any damage, such as cracks or dents. These imperfections can compromise the seal between the crystal and the bezel, potentially allowing moisture and dust to enter the watch. If any damage is present, it should be repaired by a professional watchmaker.
Examine the interior surface of the bezel, where it will make contact with the crystal. Ensure that there are no burrs or sharp edges that could scratch the crystal during installation. If necessary, use a fine-grit sandpaper or a polishing cloth to smooth any rough surfaces.
Inspect the gasket that will create the seal between the bezel and the crystal. Make sure that it is intact, free of tears or abrasions, and properly lubricated. If the gasket appears worn or damaged, replace it with a new one.
| Gasket | Lubricant | Additional Tips |
|---|---|---|
| Inspect for damage or wear | Use silicone-based grease or watchmaker’s oil | Gently press on the gasket to ensure a proper seal |
Seating the Bezel
Seating the bezel is the final step in assembling your watch, and it’s crucial to ensure a secure fit. Follow these detailed steps to ensure a proper seal:
-
Align the Bezel
Place the bezel over the watch case, ensuring that the alignment marks (usually small notches or arrows) on the bezel match the corresponding marks on the case.
-
Apply Pressure Evenly
Use a bezel press or a rubber mallet and press tool to apply even pressure around the periphery of the bezel. Avoid excessive force, as it can damage the bezel or the watch case.
-
Check the Fit
After applying pressure, check if the bezel is seated securely. It should not rotate or move easily.
-
Secure with a Click Spring
For bezels with a click spring, rotate the bezel counterclockwise until it clicks into place. This spring ensures a secure fit and prevents the bezel from rotating unintentionally.
-
Verify Water Resistance
If your watch is water-resistant, you should verify the seal by performing a water resistance test. Submerge the watch in water and check for any leaks or bubbles around the bezel.
