The odd thing is that even turning the crown in the opposite direction is very stiff (rachetting backwards.) And same with setting the time. Feels like there’s something that prevents it from moving freely.
Best bet, I’ll try to find a watchmaker nearby to take a look at it.
You’re probably right about the oils solidifying because when the watch is stopped, and I set the time, it starts running. So I assume the “setting” position doesn’t properly disengage the winding mechanism, and it winds itself up. I just set the time to 12 o’clock and it ran for 10 minutes.
That makes me think it may actually be a vintage movement, which is very cool!
