How to Replace the Battery on a Dive Watch

Replacing the battery on a dive watch is easy.

Dive watch batteries have a long life span, but if you hang onto your watch long enough, you will eventually need to change the watch battery. To access the battery you must open the case back of the watch. Fortunately, opening the case back on a dive watch is an easy and safe process.

Things You'll Need

• Flat-head screwdriver
• Small flat-head screw driver, 1 mm
• Replacement battery

Instructions

1. Place the watch on its side with the back side facing you.

2. Insert a small flat-head screwdriver between the base of the watch and the flat surface of the case back and lift upward to remove the cover and expose the battery compartment.

3. Pull out the gasket that rests between the case back and the case of the dive watch with your fingers. The gasket is a rubber ring that fits between the case back of the watch and the case itself to prevent water from entering the watch. Inspect the gasket to make sure that it is not warped or damaged in any way. If the gasket is deformed, replace it with a new one.

4. Use a screwdriver to remove the old battery from the battery compartment. Note which side of the battery is up and put the new one in the same way. Replace the gasket and the case back.
