Vintage Ladies Omega Watch 1960's?

Good afternoon. Attached are a couple of photos of what appears to be a ladies omega watch, which a great aunt received as a gift back in the 1960's. I'd appreciate any comments on the model, it's authenticity or value for that matter. I know the bracelet is not original (i.e., an omega), given its marked, well, speidel which probably means somewhere along the line the original was broken and replaced with the cheap band. Also, there is no marking on the rear of the watch; does that make it a fake or some other explanation. At your convenience. Thank you. John Drake

I've seen these quite a bit, though I'm not sure what the model name is.

It appears to be 100% authentic and original, thought it would be helpful to post a picture of the movement.

The casebacks on these models aren't usually stamped on the outside, though I have seen ones with "14k" markings before. Still, I don't believe it's a cause for concern.

Also, the band might be original. Basically every example I've seen of this watch has had a Speidel bracelet; it's very possible that Omega sold these watches with non-OEM bracelets.

Normally these sell for $100-200 depending on condition. I hope this helps!

Thank you, WatchmakerTheory. You've been very helpful and I appreciate it. Regarding posting a picture of the movement, I'm a bit thick fingered; afraid I'd damage the case trying to open it.

I bet the Speidel is a replacement for what may have been something like this originally.

Yes, i could see that, especially if the metal fittings were a silver, platinum or white gold coloring. The watch is very light so i could see a finer, less metallic bracelet as being provided. I just haven't seen any others to compare, especially in their original state. Thank you, efauser.
