Thanks, and I will try to post
I will try to locate and post the Seiko explanation of the Magic Lever. It is a mad cartoon, with a CHOOO CHOOOO! train. Amusing, but also great way to convey info. Can't see IWC doing it that way, though.

Seiko Magic Lever
In thread below this system was mentioned as being similar to the Pellaton wonding of the IWC. A post by Eightohms was referenced where some descriptions and diagrams were offered. I thought this video may help - this is from a Seiko 6309A I serviced some...
Great video Al and very informative, That Seiko sure is beaten up. In the video it looks like you did a great job of cleaning it up as good as new! Hopefully you restored it back to health to a happy owner. Thanks for sharing! -MW
