The package may indicate SR920SW (silver oxide battery), but due to some listings showing alkaline battery, these are listed as LR920.

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

The following model numbers are all the same standard battery, differing only in their markings.
Basically, batteries with the same model number are compatible, even if they are from different manufacturers.

((Important Notes for Battery Replacement))
The top surface (where the model number is engraved) is the positive (+) terminal, and the bottom surface is the negative (-) terminal.
Electricity flows when the positive and negative terminals are connected (even when held by hand).
If you grip the battery from top to bottom with metal tweezers, it will cause a short circuit. For silver oxide batteries (SR series), this can completely discharge the battery in less than 30 seconds (or about 10 seconds for smaller capacity batteries).

★The most important thing to avoid is gripping the battery from top to bottom. For silver oxide batteries (SR series), always grip the sides.

While plastic tweezers that do not conduct electricity or non-magnetic tweezers are available, it is generally recommended to always grip the sides of button batteries when handling them.
