When do you need a V399 watch battery?
This silver oxide battery is specifically designed for watches and small electronic devices that require a stable 1.55 volt voltage. You need this battery when your watch stops running or the time display becomes irregular. Silver oxide batteries deliver a constant voltage throughout their entire lifespan, which is essential for accurate timekeeping.

Why choose the V399 size?

With a capacity of 42 mAh, this battery provides sufficient energy for long-lasting use. You cannot simply use a different size, as watch batteries must fit exactly into the designated holder.

High Drain technology for reliable performance
This battery features High Drain technology, which means it is also suitable for watches with extra functions such as backlight, alarm or chronograph. This technology ensures the battery continues to perform steadily, even when your watch temporarily requires more power for these additional functions.

Compatibility with various reference numbers
The V399 is also known under the reference numbers SR927, SR927W, 399/395 and 399. Always check the battery number in your watch or the user manual to be sure of compatibility. The battery is supplied in a blister pack, which provides protection during storage and transport until the moment of use.
