so I happened to end up with a really nice 321 movement that unfortunately misses it’s movement ring. As it seems like these are not available around the corner I wonder if the ring of an caliber 861 or 1861 would fit the cal 321.
The (1)861 ring is different from the 321 ring, the 321 ring has 'windows' cut out so that the pushers can go through. https://omegaforums.net/threads/lapse-of-memory-is-the-mvmt-ring-the-same-for-321-861-speedy.19045/
