Sorry, got sidetracked.
I suspect it's one of those watches, of which there were many hundreds, made to order by one of the established factories and given a brand by the owner of the company distributing them.
It doesn't come up in my soft or hard copies or watch movement references.

It's not an unusual caliber and the bridge layout was used by many manufacturers, Alpina (as Tony mentioned), Aurore (Cal 42), Felsa (Cal 77, Cal 108), Arogno (Cal 152) and many others.

As there are no indicators that I can see (anything under the balance?) the only way to find out more is to check under the dial for the layout of the setting works which are like a watches fingerprint.
