Seeking information on Ladies Omega gold watch

Hi everyone

I'm hoping to get some more information about the pictured ladies Omega watch which was a family inheritance not so long ago.

Firstly, I know that the box does not match the watch. A new watch was bought from a jewellers in Brisbane, Australia in around 1972-3 in that box but it was subsequently lost and replaced under insurance with the one pictured. The new watch had an ETA 978.002 movement which was not working and I had it professionally replaced recently, as pictured. The watch is now working well.

I'm hoping to find out the model, if it is part of a particular series, an approximate year, and, of course, if it is desirable or not? Also, is the hour marker a diamond?

I'd appreciate any insights that you may have, and I will try to answer questions if I can.

Thanks so much in advance!

Not an expert on those but seems to be only gold plated (steel caseback, no stamps on clasp), which would decrease the value drastically. Movement is obviously not desirable. I sadly think it is not worth a whole lot (hope I'm wrong). I'd guess mid to late 1980s for this one.

Thank you so much to those who replied! I appreciate the honest feedback and insights. Have a great day, everyone.
