Murata 手錶電池尺寸選擇器

Finally, a simple way to match those tiny coin cell batteries without squinting at a chart. The two-sided design with graduated holes made it easy to find the right size for my old watch.

I was tired of guessing which watch battery size I needed until I got this simple selector. The small-to-large hole layout makes finding the right fit quick and painless for different devices.

The two-sided design is a lifesaver when I'm digging through a drawer of dead watches and key fobs. I just start at the small hole and work up until it fits snug, no more guessing games. Solved my battery headache in about a minute flat.
