Waltham caliber 402 “alarm”

[Stefen]

Anyone know how this movement comes out of the case ?? It’s either I’m going crazy or this thing is just seized in there

it's hard to tell in the picture but is there a movement retaining ring in the case? Then it's possible it goes out through the front?

Yeah I figured it out, it was just seized in there. Had to heat it up a little bit with a heat gun. 
 

having a diagram would help to reassemble lol

for a diagram if it exists we need to identify who made the movement and it's not made by Waltham. this is word be helpful to have the diameter of the watch measured on the dial side a better picture of the movement helpful for trying to identify out and any numbers or symbols found on the plates. In the absence of that the best guess currently is that it is a Vulcain Calibre 402 or possibly a 401. Depends on whether it had a calendar or not.

from the bestfit book see if this batches what you have as I'm not finding a tech sheet conveniently anywhere.

just in case I guessed correctly here's the rest of what they had not a lot but better than nothing

Wow this helps a lot, it’s a 402 caliber, made by Vulcain. I will post my assembly process once I’m done, so that others can see everything.
