Show us your vintage Omega women's watches

Hello,
Looking for some information and valuation on my Great Grandmother's Omega gold watch. There is a Patent number on the back of the clasp, which reads (as best as I can tell): 670798PRL?.

Pictures as follows:

Thank you in advance.

Hi everyone,

I’m hoping to get some help identifying and valuing an Omega watch that’s been in my family for quite some time. Here’s what I know and see about the watch:

• Type: Women’s Omega watch

• Details: gold, diamonds and gemstones (possibly on the bezel or dial) but no visible model number or serial number on the case back.

• Box & Papers: Unfortunately, the original box and papers were lost a long time ago.


• Condition: It’s in great condition, but I’m not sure about the age or model.

I’ve attached some photos from different angles to help with identification. Let me know if there are specific details or close-ups that would be helpful.


Any guidance on identifying this watch or advice on next steps to determine its value would be greatly appreciated. Thank you in advance for your time and expertise!
