No stem locking screw?

A new one on me. You might have to remove (after power has been released) the barrel bridge to see how it is attached.

Remove the other case screw and remove the bezel and I think the movement will push out from the front. I think this type of movement uses a winding system like some Pocket watches where the square part of the stem fits into a slot held within the barrel bridge and lower plate, similar to a Waltham pocket watch.

The movement is a Cyma Tavannes and the patent number refers to a negative set stem system developed by them and as oldhippy has stated it is similar to those found on some American pocket watches.

Thanks for the information. I thought that I might completely dismantle this movement as it has no value but the balance appears free. I have yet to attempt a full dis-assemble and clean (and, with luck, re-assemble). Failure is definitely an option in this case!

Thanks again.
