A watch battery, or a button cell, is a small single cell battery shaped as a squat cylinder. Devices using button cells are usually designed to use a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge and hold their charge for a long time if not used. A metal can forms the bottom body and positive terminal of the cell. The insulated top cap is the negative terminal.
Replacing a watch battery is a skill. We are proud to offer this service. Our watchmakers recommend a full re seal with battery replacement. This will properly keep out any dust and moisture.
