Very nice Thomas. And nicely presented.
Of your six images, leaving aside the last (too new for me), I think these are all calibre 38.5. A very successful movement produced from 1932 for over 30 years.
In the first image, these three are ref. CK374 (Yann has written about this before, with different dial and hands it was the Quarantenaire from 1934).

In your second image, the first three are joined (top left) by a CK1021.
In your third image, these two are CK1064 (Omega’s first water-resistant watch, dating from 1937).
In your fourth image, I think these three are all (different) CK374 again.
In the ‘family group’ there are three additional watches in the middle of the back row (harder to identify).
Very nice! Tom
