Silver oxide vs alkaline — does it matter?
Always use silver oxide in watches — not alkaline. Alkaline equivalents have a declining voltage curve — your watch will run slower as the battery drains. Silver oxide maintains a steady 1.55V until nearly depleted, giving accurate timekeeping throughout its life.
Watches that use 390
Standard battery for Swatch Originals Gent and Swatch Gent Pro ranges. Also found in many Casio, Pulsar, Lorus, and fashion watches with larger case sizes.
Always check the code on your existing battery or the caseback of your watch. If unsure, a jeweller can confirm the correct size without replacing the battery.
