Following the guidlines, I'm pretty sure it isn't an ETA copy that my watch is, I'll double-check again though.
I took the caseback off thinking it might have had something to do with the anti-magnetic cover. It has been running fine for almost 2 weeks now, but I just noticed that it had stopped on me about 20 min ago. Anyhow, what is weird is that I can move it around a bit and it won't start back up, but the second that I unscrew the crown to reset the time, the second hand starts moving again.
