Thanks. Still doesn't alter the fact that I can only find reference in Barrie's book to a ladies watch!
These are odd things - the cases and movements often don't "match" in quite the way you'd expect, but, as suggested above, this could be due to cases being produced earlier and stockpiled. The cases themselves are a bit smaller than "normal" watches. It's possible that these were presentation watches to ladies, I suppose...?
Anyone got the dial size on these (in mm if possible)
Re the Bensons, these cases also pop up in gold, rolled gold, etc, with Swiss movements. Like the Smiths, some of these cases appear to be halmarked in the 40s, but with fifties paperwork.
