Consumers should always use a watch professional to change a battery. They shouldnt try to open the watch because they might mar the case or damage the water-tight gasket or the movement, which could void the warranty.
Repairers should check the watch contacts and battery for cleanliness and clean the terminals with a lint-free cloth.
Always insert batteries correctly, matching the polarity (+ and -) marked on the battery and watch.
Remove spent or dead batteries immediately to avoid leakage that will damage the watch.
Dispose all batteries properly to protect the environment.
A professional should dispose of spent batteries, preferably to a battery recycling program or other appropriate waste collection facility.
Dont heat batteries or throw used batteries in the fireplace or incinerator. This can result in leaks or explosions.
Do not mix unpacked batteries. When unpacked batteries are mixed together, they can easily short-circuit each other, particularly button-type batteries. In some cases, this can be dangerous because batteries can heat up and cause an explosion.
Do not give children access to batteries. Keep all batteries out of their reach, especially small ones that could be swallowed. In case a cell or battery has been swallowed, seek medical assistance promptly.
