So it seems a few of you on Oppo like watches, so I’m hoping some know how to repair them. Halp please.

I think the model is FS4531, and it died a few years ago. I bought a bunch of tools to try and change the battery, and ended up spending more than just taking to to a shop.

I can’t get the damn back off though. First I bought the tool to get it off, which didn’t work, the tool kept slipping. So I bought a vise for it, and I STILL couldn’t get it off.

Anyone have any ideas? If not I’ll eventually take it to the Fossil outlet, unless you guys know they do any repair at the stores.
