This will never be a complete list, but there does not seem to be a good list of watch battery type by model online to even get an idea. Have to start somewhere! Owner’s manuals are not always available so usually you have to open the watch and take out the old battery.

Watch Batteries in a Flash has this good cross reference once you know one of the battery identifiers.

Silver oxide batteries are the high-drain type for watches with large, bright illumination.

Alkaline batteries are “normal” watch batteries.

Also, from Watch Batteries in a Flash, PRO TIP: If you are having a hard time determining your battery, measure the width of the battery and then the height. Use the dimensions against the Dimensions column to find the battery that you need. You can also use a micrometer to measure the inside of a battery cavity to find out which battery you need.
