The package may indicate SR920SW (silver oxide battery), but due to some listings showing alkaline battery, 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 just different notations and are all the same specification batteries.
Basically, if the model number is the same, they are compatible even if the manufacturer is different.

((Precautions when replacing batteries))
For this battery, the top surface (where the model number is engraved) is positive (+), and the bottom surface (back) is negative (-).
Electricity flows when the positive and negative terminals are connected (electricity flows even if you pinch it with your fingers).
If you pinch both the top and bottom of the battery with metal tweezers, it will cause a short circuit, and if it's a silver oxide battery (SR series), it will be completely discharged (empty) in less than 30 seconds (about 10 seconds for batteries with smaller capacity).
★The worst thing you can do is pinch the battery from top to bottom. For silver oxide batteries (SR series), pinch the sides.
There are also plastic tweezers that do not conduct electricity, or non-magnetic tweezers, but basically, always pinch the sides when handling button batteries.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
