Casing a Omega Dynamic 136.033 / Calibre 613 / Case clamps

Aludic · Sat. 1:12am

Hi all,

A little while ago, a fellow forum member sourced a whole host of Omega parts, including some cases, dials and movements. In the meantime, I have had the chance to practice my watchmaking skills assembling watches out of these, which occasionally brought challenges like finding the correct case clamps, stems, etc. So far, so good. Except for this one.

This Omega Dynamic 136.033 case and dial should take the 613 calibre movement, but I cannot for the life of me manage to get it assembled. Online sources suggested the 550-1911S case clamps, which I've sourced, but that really doesn't seem to fit. I've been searching the forum and found a topic concerning a wedge to keep the movement from turning inside the case, but no mention of the clamps. That said, my first concern is sourcing the correct case clamps to be able to slot it into the case to begin with.

Does anyone have the solution for me? What case clamps do I need? Any other parts (like said 'wedge') required too?

Thanks in advance for helping me revive another watch for someone to enjoy.

EDIT:
Nevermind me, you have the wrong case clamps. It appears i did not take photos of the movement when I last serviced a dynamic, but you can see the clamp you want in this gallery from watchguy

If I am not mistaken its part 550-1998

rotate the movement to line up the case clamps with the cut outs at about 4 and 10 on the case and it should drop in, then rotate the entire movement so that the stem lines up with the crown tube and you can slide in the split stem.
if you look at the dial there is also a small notch at 4 and 10 to allow you somewhere to push against to turn the whole movement when it has the dial and hands on as you would when casing/decasing the watch.

the wedge is to make it such that the joint part cant get any sideways movement and potentially come loose, but if i recall correctly this was something that was added later as a security measure and it should still function without it, though it would be better to have it ofc.

Movement wont be solid in case but if you feel current clamps has large gap between case I would advise bent them ( turn them abound first ) or use non Omega clamps assortment
Glass and tension ring must be right is very important and it holds the movement inside by pressing + stem makes it solid inside
