Help identifying an 18K Omega Quartz Cal.1332 with no visibl

Title:

Hello everyone,

I would appreciate your help identifying this vintage Omega.

I have spent several weeks researching it without success and I have not been able to find another example with the same configuration.

Known details

• Omega quartz movement Calibre 1332
• 17 jewels
• Estimated production around 1979–1982
• Solid 18K gold case
• Inner caseback hallmarked "18K 0.750"
• Original Omega signed crown
• Champagne dial
• Gold fluted bezel
• Integrated solid gold bracelet

The watch has remained in my family for many years and, to the best of my knowledge, it has never been modified.

The movement appears completely original and is consistent with the period.

What puzzles me

The inside of the caseback only carries the 18K / 0.750 hallmark.

I have carefully examined it several times under magnification but I cannot find any Omega case reference anywhere inside the caseback.

This has made it impossible for me to identify the exact reference.

I would really appreciate your opinion on the following:

1. Has anyone seen this exact model before?

2. Is it normal for some late-1970s or early-1980s Omega gold cases not to have a visible case reference?

3. Could this be a factory Omega fitted with a locally manufactured 18K gold case?

4. Does the bracelet appear to be an original Omega bracelet from this period?

5. Is there anywhere else on the watch where I should look for the case reference?

I have attached photographs of:

• Dial
• Movement
• Exterior caseback
• Interior caseback
• Bracelet
• Clasp
• Hallmarks

I would be very grateful for any information or opinions.

Thank you very much for your time.

Here are the pictures

Looks like a hand made case. Except for 18kt. No other gold marks. No local manufactures name. Some countries imported the movements and had local manufactures make the cases.

More value in the case and band (if band is also 18kt).

Thank you very much for your opinion.

Based on your experience, assuming the movement is original Omega and the case and bracelet are both solid 18K gold, what would you estimate to be the current market value of this watch?

I understand it is only an estimate, but I would be very interested in hearing your opinion.

AS XJR said. As it's not an Omega watch. It would be bought for weight. If outside links are solid. You have a bit of weight there

Find a scale and weight it Best if movement out
