IWC movement help

I recently inherited several movements and there is one that I really would like to learn some more about. I can´t find anything similar on the internet... Has someone any information about this movement? Thank you for your help!

Kind regards,
Birka

Hi Birka,

Welcome to the Forum.

Movement details from the Watch International series

I've shown your movement with a Reference 6800 which could be the the correct case. Just a guess.

The Ref 6800 is shown in the 1981 catalogue
