A friend of mine has a vintage pocket watch with Lackawanna 17 Jewels on the face, but it's not clear who the manufacturer is even after I examined the movement. The dial is white with European-style black numbers (therefore could be from a Swiss manufacturer), the hands are full moon-style and the case has a streamlined steam engine on the back in high relief. A Google search didn't turn up anything useful. Any help with further identification would be appreciated. Thanks!
