This is a handy little case opener. It's easy to adjust, and it does exactly what it's supposed to do. Unfortunately it won't open watches with small holes on the caseback (Omega, IWC, Breitling, etc.) because the pins are elongated, and they won't fit in the holes. It's best for opening watches that have notches around the outer edge of the caseback (Tag Heuer, some Seikos, Citizens, etc.).

I'm thinking I might be able to file down the pins to make them fit into other watches. If I break it, so what. It was less than $5.
