This big screw holds a lever that allows the movement to switch between winding to setting modes. Every now and then I run into one that has the head broken off. Every now and then I run into one that is insanely tight, such as this one. It actually took me awhile to get this screw out.
Why is this? Because someone turned it the wrong way, with a lot of force. Because this screw is "left handed". It tightens and loosens the opposite way of usual screws. There's a good reason for that.
There's a small amount of rust, but it cleaned up fine. No issues with this one.
There was a rather large beat error, but otherwise it's good. I hope the hairspring collet isn't loose. We'll see how it goes.
Ready for a few days of testing... There shouldn't be any trouble.
