picked up a 756 tegimented on the bracelet. pretty nice watch with typical sinn accuracy and detail. no scratches even after running it along the door edge by accident. the ar is much improved over the sinn u1. not sure if its any different, but doesn't smudge as easy. its 40mmX14mm in height. Its not a large watch. I have plenty of those. the lume though is not very good. it does last through most of the night, just enough to be visible which I guess is the point.
