Family old story. Please help identify this vintage omega

[vigenere]

I need some help identifying this Omega watch. I don’t know if it’s real or fake.
My mum purchased this more than 40 years ago.
It does not run anymore and we have no idea how the strap and crown broke when it was stored inside the watch case.

Dial only shows omega and swiss made.
No wordings on the back case.
375 and Italy on the watch clasp.

Hello @vigenere and welcome to the forum! In the mid- to late-1970s, Omega produced a line of women's jewelry watches with diamond bezels. Stylistically, your watch looks like it came from that period.

If you want to learn more about your watch, consider taking it to a watchmaker near you and ask them to open the watch. Inside the watch case you will see the watch movement and some numbers on the inside of the caseback. The numbers on the inside caseback are the factory model number for your watch. The string of numbers on the watch movement is the movement serial number, and that can be used to roughly date your watch. You can find tables online that can help you with that.

Here are a few catalog images of similar watches, circa 1974-1977:
