What battery does a Wristwatch take?
1 × LR44 battery
Most standard quartz wristwatches use a silver oxide button cell — SR626SW (377) is the most common. Always check the battery inside your watch for the exact code. Use silver oxide, not alkaline LR44, for accurate timekeeping.
If your Wristwatch 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.

Watch batteries vary by brand and model. Unlike most devices, there is no single universal answer — the correct battery depends on the specific watch movement inside.
Most analog quartz watches use a silver oxide button cell — SR626SW (377) is the most common globally. Some use SR920SW (371), 390 (SR1130SW), or others. Digital watches (like Casio) often use a lithium CR2016 or CR2025 instead.
The safest approach: open the caseback and check the code printed on the existing battery. We are currently building a comprehensive watch battery guide with specific results for hundreds of watch models — check back soon.
