Hello Wilson,

If you Google, "Hamilton Poor Man's Heuer", a few pop up.

The movement on the one you've posted should be signed, the crown, as well, otherwise it's right.
A friend of mine was also interested in it, but decided against for the reasons I've mentioned.
In my opinion, it was put together by someone, using NOS parts.
It's a nice piece, the question is, can you live with it knowing its movement is not signed and most likely it didn't leave the factory the way it is?

Regards
