The best way to know is to see inside the caseback of this one to see if more than one reference number is listed. I don't know (I'm sure someone does) if Omega used the same case design for either automatic or manual movement.
There are similar cases for manual wind DeVilles but there are a lot with drawings so you'd need to Google those references to see what they look like. https://www.omegawatches.com/vintage-watches?product_collection=3177&v_watches_movement=2776
This is a watch I do not own.
Never took the back off mine stamped on the back is tool then a number.
This watch for me is hard to find only the gold plated one above is the same type mine was s/s
I did look through the Omega web page but it’s not there.
Not my watch.
That’s the watch I am looking for Thank You
Bought it on its way.
Thank you again been looking for that model a long while.
Not a nice looking watch but it’s the model that was bought for me.
I thought you wanted a manual wind with no date. I gave you the link to the Omega Vintage database. You might try looking there for the reference number.
