It would be an Omega watch. Some times jewelry stores would also put their names on the dials. There were also a fair number of watches that had corporate logos added. Usually for watches that were given out as anniversary gifts for years of service.
If you pick up some Poly watch from Amazon you might be able to clean up the crystal a little. It’s cheap and would give you a much better look at the dial. It would allow for some better photos too.
In the end, if you want to keep the watch you need to have it serviced. If you wanted to sell the watch I’d just polish up the crystal with poly watch, don’t bother spending the money servicing it before selling it.
