Adapted omega military pocket watch or frankenwatch?

Dial and hands are not Omega. Doesn't look like it runs, either. You've got some issues with the hairspring.

Do you own it or thinking of buying it?

It’s a pocket watch that’s been converted to a wristwatch and someone has repainted the dial to make it interesting. It has very low monetary value and little collector value.

If you’re thinking of buying it, I wouldn’t bother. If you already own it I wouldn’t bother spending too much time and money on it

Agree with all above.
The Caseback markings are of interest.
The overlapping coins above the Omega on Caseback signify the Grand Prix award in Paris in 1900 to the entire Omega collection. This was a prestigious award and Omega had it inscribed on many picket watches at turn of century. It has nothing to do with specific reference or caliber it was used widely by Onega on watches of that era.
When I first saw it I thought it must be related to the specific watch I was considering but with a bit of research I learned otherwise and passed on the overpriced offering.

Eastern European Special...complete fantasy dial....worth is silver scrap value
