Welcome - Great entry to the Forum.

This is the first ever IWC Aquatimer model, ref 812, launched in 1967. The age can be determined by running the serial numbers of the movement and case through the Date-your-IWC site.

A highly collectible watch, also with a substantial economical value.

Looks like it is in an untouched original condition. I you consider a service/renovation, make sure to not replace hands/dial and I wouldn't even have her polished.

Thanks for sharing.

Thank you very much for your invaluable reply.
I apologize for my ignorance, but to access the serial number I would have to have the watch opened by a specialist correct?
Many thanks once more.

Yes, you need to have it opened to find the #'s.

Many thanks once again for all the info.

My best regards

Feel free to send me an email, I may have some offline info for you.
