373 SR916SW Watch Batteries

The 373 battery, also known by its IEC code SR916SW, is a 1.55V silver oxide button cell measuring about 9.5mm across and 1.6mm thick. Here you will find every 373 watch battery we stock, from Renata, Maxell, Seiko, Murata and Seizaiken, so you can pick the brand you prefer.

The easiest way to check you have the right battery is to read the number printed on the old one, then match it to 373 or SR916SW. Silver oxide cells hold a steady voltage for most of their life, which is why watchmakers prefer them for quartz watches.
