Where's the Click?

I'm working on a Waltham 8 Days aircraft clock from WWII. It has dual mainsprings which are wound up. I need to unwind them before going any further but am unable to locate the click. It appears that any further disassembly will affect the drive train. Am I overlooking something obvious?

Some of the older watches would have a leaver on the side near the winding mechanism. You would put some tension on the mainspring while depressing the leaver and then slowly release the mainspring. Need pictures of the side/edge of the movement.

Thanks, jdrichard. That led me to the click. The first photo shows the click which disappears in the second photo as the watch is wound.

No problem. I’m not a pro, but I have a lot of pocket watch repairs under my belt. Old Hippie OH is the pro.

Looks like a Waltham CDIA aircraft clock.

I've got one sitting no more than 1 foot from me now waiting for me to clear some other projects before I work on it.

I've got the parts list and a diagram of parts, but its one of the few Waltham aircraft clocks I don't have an exploded diagram of.

I've got a small collection of WWII aircraft clocks and have in the post coming to me my first German aircraft clock.

If these clocks interest you for made in USA Military timepieces I recommend the book 'Military Timepieces' by Marvin E Whitney

Mostly USA, for British Military Timepieces you need funnily enough 'British Military Timepieces' by Konrad Knirim, just be prepared for a price shock as  Whitney's book is not cheap, but Konrad's price is out of this world, but they are the best reference books for British and USA military timepieces, Konrad's is full of great colour photos, whilst Whitney's book is filled with exploded diagrams and service manuals.

      Incabloc Lyre Spring & Low Earth Orbit

      Just a note for those who come searching for information on this topic in the future.  I did eventually find the Mark's video on how to replace these springs, as someone observed, he does in fact make the replacement look easy.  (It actually is relatively easy once you have the knack of it.) If you're enrolled in one of Mark's online courses, the demonstration of how to replace this spring is in the Bonus Videos section of his course site, and is called "C2B1 – Sea-Gull Style Shock Springs".

      If the metal was twice as thick, it wouldn't snap so easily.  The thickness is governed by the space available so you can't use thicker metal.  If you glued two pieces together, the likelihood of snapping would be reduced.  That's my theory anyway, could be wrong.

      there are various approaches to learning watch repair. A lot of people want to jump right in and every single watches something to be repaired restored. But other times like this it's disposable it's here for you to learn and when you're through learning you throw it away. yes you definitely should try this you have a learning movement you need to learn and the best way to learn is by doing something.

      Sorry, the friction will be so great that the wheel will barely turn, if the movement will start at all, the amplitude will be verry lo.

      If I can’t re-pivot the wheel, the logical thing to do is to descend the pivot hole.  Plan is to either stick a suitably sized hole jewel (from a barrel bridge or something) or fashion a blob of epoxy on the underside of the escape wheel cock so the wheel sits on its one pivot on the base plate and the staff with the broken off pivot (which I’ll polish as best as I can) becomes the upper pivot. As long as it doesn’t foul the 4th wheel it should work? I know it’s a bodge job, and if this were a rare movement, or belonged to someone else I would not do this. I’m just interested to see if I can get the thing to run.
