The package may indicate SR920SW (silver oxide battery), but due to some listings showing alkaline batteries, we are listing this as LR921.

Generally, SR model numbers, which are silver oxide batteries, have a stable voltage and are suitable for watches, but they are more expensive.
For simple analog watches, use cost-effective alkaline compatible batteries.

The model numbers below are all the same standard batteries, differing only in their markings.
Basically, if the model numbers are the same, they are compatible even if the manufacturers are different.

((Precautions when replacing batteries))
The top side of this battery (the side with the model number engraved) is positive (+), and the bottom side is negative (-).
Electricity flows when the positive and negative terminals are connected. (Electricity will flow even if you hold it with your fingers.)
If you use metal tweezers to grip both the top and bottom of the battery, it will cause a short circuit. For silver oxide batteries (SR series), this will completely discharge the battery (empty it) in less than 30 seconds (or about 10 seconds for batteries with smaller capacity).
