Yikes. That case back is scratched up nicely. Also for those who seek the watch tool you can purchase online at Amazon. They are not that expensive.

I have the festina 16040 do you know what battery it has?

Pipelyon says:

He forgot to mention the one without notches has one place made to pry it up. It’s a slight over hang, allowing the tool to grab the back.
