Hi Kevin and welcome to the forum!
The OXG stamped on the movement is the U.S. import code for the Norman Morris company. It very well was imported just as a movement and cased in the U.S. and could have been most anything.
While attractive, it is of little monetary value and I would use it for parts unless you have a strong attachment to the watch.
Restoring is impossible but you may find a donor watch with a bad dial or movement to build your "franken". The best way to be sure it will fit is to find a case already housing this movement.
Good luck!
