So, yeah, I'm an idiot. I attempted to regulate my Sumo using the adjustment lever and must have been too rough. Now the balance wheel wont turn. I can move it manually, but it will no longer oscillate.
I do love the watch, but I also know its not the most expensive in the world. Is it worth it to try and get it serviced? It was running ok before this, just a bit slow.
No idea how much something like this would cost or who could do it, would love to hear any ideas you guys may have.
