While the packaging may indicate SR927SW (silver oxide battery), due to some listings showing it as an alkaline battery, we are listing it as LR927.

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, consider using the more affordable alkaline compatible batteries.

The following model numbers are all the same specification batteries, with only different markings.
Basically, batteries with the same model number are compatible, even if they are from different manufacturers.

((Precautions When Replacing Batteries))
The top side (where the model number is 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 them with your fingers.)
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), please grip the sides of the battery.

There are also plastic tweezers that do not conduct electricity, or non-magnetic tweezers. However, as a basic rule, always grip the sides of button batteries when handling them.
