Can anyone help me figure out how to fix this watch? I had seen a video that said it was likely that Center screw being loose so it wouldn't wind, but even after tightening that it won't start ticking. Bought some simple tools and I'm willing to mess with it (I believe it was a cheap watch) I just have no clue what to do.
The calibre 7s26 is a workhorse movement and fairly simple. If you have the time and is pretty handy, you can try to follow this guide https://www.youtube.com/watch?v=cHF9xMJ7tmQ to disassemble it and check what's wrong.
Otherwise, you can bring it to an independent watch repair shop. It would be less expensive than the swiss counterpart.
