Greetings all, I am restoring a Seiko Lord Matic (5206A) and have a question about the automatic works rotor. When I opened up the watch the rotor was very loose and (fortunately) this was due to it not being screwed on very tight and not a bearing problem and I removed it with a few turns using my fingers. However, the thought struck me that I'm unsure how to put it back on, what tool should I use as it is a chunky rectangle and not a slot type where I could use a screwdriver (see picture below - Note: this is a similar movement picture from google as the picture I took of my watch isn't as clear). I don't want to grip and try to tighten it with tweezers as I think the chances of slipping would be high and I probably couldn't apply enough torque this way before damaging my tweezers and/or slipping and scratching up the watch. Anyone have any ideas what tool I can use for this job? Maybe I could 3D print something if there is no easy answer out there?

Hey i recently picked up an older seiko to use as donor parts/ dial when i want to try to build a watch of my own. I didn't expect it to work however when it came in it did work. Besides a slight rattle. I wound it doing the seoko shuffle for a bit and it worked well. I decided to look inside thats when i realized the rotor was loose looks like it just popped off of the stem that it spins on. I didnt see any screws to hold it to said post i layed it back on loosely and it would intermittently have its gear line up with the other gear right near it but after setting it back on to always light up with that gear now it doesnt seem to wind itself anymore. Anybody know where to go from here or whats going on?
