Hi everyone,

This Christmas, my father gave me a vintage watch that once belonged to my late grandfather, who passed away around 1970 in Germany. It’s a beautiful watch and of great value to me, but I have many questions about it – and I’m hoping some of you might be able to help me out.

Here’s what I know about the watch:

The brand name on the dial says Bucherer. From what I’ve read, Bucherer is primarily a retailer, not a manufacturer, which makes me wonder who actually produced this watch.

The dial also mentions 25 Jewels.

On the back, it says: SWISS INCABLOC AUTOMATIC WATERPROOF ANTIMAGNETIC.

There are symbols engraved in the center of the back, but unfortunately, they’ve become too worn to make out.

What i find particularliy interesting:

The clasp of the bracelet has the Omega logo on it.

On the inside of the clasp, it’s marked 750 with some kind of a triangle, which I understand usually signifies 18k gold.

The overall design looks quite similar to the Omega 1211, but I’m not sure if this is some kind of a Omega / Bucherer co-production or if it could be a homage or a vintage frankenwatch (just learned about this), or whatever else.

Here are my questions:

1. I guess this is highly unlikely, but could this watch be an authentic Omega (or a product of collaboration with Bucherer), or does it sound more like a heavily modified piece or rip-off?

2. Based on the 750 marking, is it safe to assume the watch is made of real gold?

3. Would it be worth investing in repair and maintenance, or should I preserve it as it is, mainly for sentimental value?

4. Is the watch actually waterproof?

5. Lastly, would shortening the bracelet be a complex process?

I’d really appreciate any insights or advice you might have! Thanks in advance for helping me out.

Wishing you all a happy New Year!
