Hello Everyone.
I am hoping someone hear has some info on this watch and its unusual regulator. The Regulator has a patent pending and the watch is also marked with a patent from 1910. Any idea who made this???

I tried researching the patent but could not find it. To me it looks like the patent on the movement is May 24, 1904. Henri Sandoz which I think became Tavannes also use that same patent date.

Hello Tom, You are correct at 1904. Thanks.

Looks somewhat like some Eaton Canadian watches I have done recently. Tavannes did all sorts of stuff including some nice "Swiss Fake" cc's of Waltham 1857's.

This is the best help I can be.
