Watch Battery Replacement Tools

Change a Watch Battery at Home

Explore our range of watch battery replacement tools for opening, handling and closing compatible battery-powered watches at home.

Changing a watch battery involves more than removing the old cell. The watch case must first be opened using a tool suited to the case-back design. Common types include snap-on case backs, screw-down case backs and backs secured with small screws. Using the correct tool can make the process easier and help reduce the risk of scratches or damage.

Snap-on watch backs are normally opened with a suitable case-opening knife, while screw-down backs may require an adjustable case-back wrench or compatible opening tool. A watch case holder can keep the watch more stable while you work, and non-magnetic precision tweezers allow small batteries to be handled without touching them directly.

Once the replacement battery has been fitted, the case back must be secured correctly. Some snap-on backs can be difficult to refit by hand and may require a watch case-closing press with a correctly sized die. Care must also be taken around the case-back gasket, which helps protect the watch from moisture and dirt.

Our collection will include individual tools and complete watch battery changing kits for occasional home use. Clear product information and step-by-step guidance will help you identify the case-back type and select the appropriate equipment before starting.

Please remember that opening a watch may affect its water resistance. A pressure test is normally required to confirm water resistance after the case has been opened. Valuable, complicated or water-resistant watches may be better serviced by a professional watchmaker.
