These are pretty well-documented, but always interesting to see. They greatly resemble Tudor watches from the era (even to the asymmetrical drilled lug holes), so indeed I'd expect to see a Tudor movement inside, although that's really just a guess. The case and case-back might even be Tudor. If the watch is in your possession, why not post photos of the inside? That would be preferable to guessing. You might also want to crop your photos before posting; the current images are 90% background.
