not sure of this movement any help?
looks like early omega to me

Hi Peter

No omega type 'Systeme Glashütte' watch - this refers to the plate design; swiss made.

Very likely the manufacture below (left side pictures). Don't get confused by the micro regulator. These were special additions depending on the the market. And there was supposable a finishing etablisement involved, but without marks ?

Gerald

Thank you once again.
