Identify this BMW watch

[632 Regal]

Searched until I wore my keyboard out. Not a single match in any photos, dealerships or promotions.

All I know is it was from Germany. Don't know what age it is or any details other than that.

The back is covered with a plastic peel off thing, not scratched as it looks.

Any help appreciated.

Strap and watch frame look like my late 1970s Seiko automatic. But the back doesn't appear to have the shallow castellations for removing it. Any clue from the details on the fastener or does it just say 'stainless steel'?

Stainless steel only. Nothing to identify on the inside either when I changed the battery. A real mystery so far.

Have searched for more than an hour, but cannot find anything like that in the net.

Thanks for trying Erich. Very elusive watch for sure. I don't and haven't wore watches so it makes more sence to sell it than to keep it just sitting all alone. Hoping to figure it out and find someone that will appreciate it.
