390 SR1130SW & 389 SR1130W Watch Batteries

The 390 battery, also known by its IEC code SR1130SW, is a 1.55V silver oxide button cell measuring about 11.6mm across and 3.0mm thick. The 389, or SR1130W, is exactly the same size. Here you will find every 390 / 389 watch battery we stock, from Renata, Maxell, Seiko, Murata and Seizaiken, so you can pick the brand you prefer.

The SW version is made for watches with a low power draw, such as most simple analogue quartz watches, while the W version suits watches that draw more power, for example those with alarms, backlights or chronograph functions. If you are not sure which you need, fit the same type as the battery that came out of your watch.
