The correct battery for an Armitron watch depends on its exact model and movement. A model name or a generic watch-battery chart is not enough to confirm fitment.
How do I identify the battery for my Armitron watch?
- Find the full model or reference number on the caseback or watch paperwork.
- Check that model’s manual or contact Armitron support for the specified cell.
- If the watch has already been opened by a qualified repairer, compare the number and chemistry printed on the original cell with the model documentation. Do not choose a replacement from a similar-looking cell or voltage alone.
If you are unsure how to open or reseal the case, have a watchmaker replace the battery. Ask whether the gasket and water resistance will be checked after reassembly.
Can I use a 395 battery instead of a 394
Do not assume a 395 can replace a 394. Common cross-reference guides identify 394 as SR936SW and 395 as SR927SW: both are silver-oxide cells, but their dimensions differ. Use the exact number printed in the watch manual or specified by Armitron; a similar voltage or diameter is not enough to establish fit.
