What battery does a Casio Watch take?

1 × LR44 battery

Casio watches vary by model. Most analog Casio quartz watches use a silver oxide button cell (SR626SW / 377). Many digital Casios use CR2016 or CR2025. Always check the caseback or existing battery for the exact code.

If your Casio Watch has stopped working or is unresponsive, replacing the battery will usually fix it. Tap the button below to find the right LR44 battery on Amazon.
