6. Test the watch
Once the battery compartment is secure, replace the watch back and verify that the watch is functioning correctly.
Closing the Watch Case
Once the battery has been replaced, it’s time to close the watch case. This process requires careful handling to ensure a secure and water-resistant seal.
1. Align the Case Back
Orient the watch case back so that it fits properly over the watch movement.
2. Press the Edges
Using your fingers or a case press tool, apply light pressure evenly around the edges of the case back to seat it in place.
3. Tighten the Screws
If the watch case is secured with screws, use a precision screwdriver to tighten them in an alternating pattern. Apply gentle torque to avoid stripping the threads.
4. Check the Gasket
Inspect the gasket or O-ring around the case back to ensure it’s properly seated and free of damage. If necessary, apply a small amount of silicone grease to lubricate the gasket.
5. Use a Case Back Press
For water-resistant watches, use a case back press to apply even pressure and create a secure seal. Follow the manufacturer’s instructions carefully to avoid damaging the watch.
6. Test the Water Resistance
| Test Method | Procedure |
|---|---|
| Submersion Test | Submerge the watch in water at a depth of 1 meter for 30 minutes. Observe for any water ingress. |
| Pressure Test | Use a professional pressure testing device to simulate a specific water depth and duration. |
If the watch passes the test, it is ready for use. If water ingress is detected, the watch should be taken to a qualified watchmaker for further inspection and repair.
Testing the Battery
To test your watch’s battery, you’ll need a multimeter. Begin by setting the multimeter to the “DC Volts” setting. Next, touch the positive probe of the multimeter to a known good connection point on the watch (often the back or side). If a battery terminal is accessible, you can attach the probe to it. Otherwise, you can gently press the probe against a metal part of the watch that is connected to the battery, such as the case.
Then, touch the negative probe of the multimeter to the negative terminal of the battery. This is typically the metal back or side of the battery, although the multimeter instructions may provide additional guidance specific to your model. A digital multimeter will display the voltage of the battery on its screen, while an analog multimeter will move its needle to indicate the voltage.
Compare the reading on the multimeter to the voltage specified on the battery. If the voltage is significantly lower than expected, it’s likely that your battery needs to be replaced. Additionally, if the voltage reading fluctuates significantly or displays “0” volts, this is also an indication that a battery replacement is necessary.
Special Considerations for Waterproof Watches
Waterproof watches require special care when changing batteries. Follow these additional steps to ensure your watch remains waterproof:
1. Ensure the crown is fully screwed down to prevent water from entering the watch.
2. Use a specialized tool called a caseback opener to open the watch case. Do not force or pry open the caseback, as this could damage the seal.
3. Gently remove the old battery using tweezers or a non-metallic object.
4. Inspect the watch case and gasket for any damage. Replace the gasket if necessary.
5. Insert the new battery into the watch, making sure to align it correctly.
6. Tighten the caseback using the caseback opener.
7. Test the watch’s water resistance by submerging it in water for a short period of time.
8. If your watch has a screw-down crown, ensure it is fully screwed down before submerging the watch in water. This will create a tight seal that prevents water from entering the watch.
