Typically on the majority of American pocket watches the movement is set up similar to yours. This is where the watch itself has no stem as that is in the case. So your movement is fine make sure when you're putting it together to lubricate all of the stuff associated with the setting so it's slide smoothly.
Link down below so you can look at the pictures. It's not really important but you're missing the micro regulator adjustment. You can still regulate the watch fine without it.
Then the crown is most definitely does not look like the right crown for this particular case. It almost looks more like a wristwatch style crown for American watches. I went attached some images you can see what the wristwatch version looks like. Also a picture of the typical pocket watch stem and sleeve arrangement.
Amazing is an understatement. Here is what I got accomplished last night...
I got the entire motion works back together. It actually runs great. The oscillating weight spins nice and free. The mainspring barrel is only supported on one side, but it really doesn't seem to have any adverse side effects. Everything was mostly surface rust. I scrubbed everything with a bit of peg wood and it all came off. Any pitting was very shallow, just barely under the plating. I dug out a screw from an older junk Seiko I had to replace the missing bridge screw. I'll work on the keyless works and the day/date components tonight.
Thank you Watchweasol. Both of these PDFs are great and just what I need at the moment. You’re right-the 2nd one is a little over my head, but I am very interested in measuring accuracy of watches, and this helps explain things. Thanks again!
