How to Replace Your Watch Battery Safely
When replacing a watch battery, handle the cell carefully and avoid touching both sides with bare fingers for long periods. Oils and moisture can affect the contacts, so clean, dry handling is recommended. If your watch is water resistant, a professional replacement may be the best option, as the case seal should be checked after opening.
Install the new SR1120SW / SR1121SW battery in the same orientation as the old one, usually with the positive side facing upward. If the watch does not start immediately, make sure the contacts are clean and correctly positioned. For valuable, vintage or sealed watches, ask a qualified technician to perform the replacement.
