Help to identify 40-50's Omega

Hi Guys,

Switzerland being Switzerland, land of chocolate, banks, watches and watchmakers, I managed to buy an old watchmaker personal stock, with mostly books, tools, some watches and parts.
No special speedmaster dial to my regret. 😁

In there, there is some things I need your knowledge for.




1 - The Salmon Dial

It seems ok to me. Not a redial.
It looks like to be from a reference 2374 (my guess), but the hands in the pack don't match this reference.
There was a 2398-1 NOS case too, but I don't think it's ok.

Any idea ?




2 - The Constellation patchwork

There was several parts : a Constellation crosshair dial with hands, a 352 movement and a 2652-22 case.
The dial seems good too.

The 352 and the dial fit well, but the 2652 isn't large enough for the dial.
It looks like a 2648 dial/movement, but how to be sure?




Thanks for your help!

This first picture looks like Christmas! Are all these boxes full of watches???!

Looks like a 2852 dial which was refinished in 167.005 style.

nooo, Mostly tools. 😀
But it was like Christmas to me! Opening all these boxes and see all these treasures was very cool.

Your dial and this one show up in a search

I don't have knowledge and skills to use these tools. I guess I'd like better watches 😀

What do you mean ?
