Watch Battery Cross Reference
Find the equivalent of any silver oxide watch battery across Renata, Energizer, Seiko, Citizen, Timex, Bulova and Varta numbers, with the matching cells we stock.
- SW = low drain (analog watches). W = high drain (digital, alarm or light functions). Same size, different chemistry, so match the drain type.
- Sizes are diameter × height in millimeters.
