Under the dial is Hamilton's 22 jewel, 12/0 sized 770 movement.
I recently found a nice Norman on eBay in need of a little TLC. It was missing it's crystal and hour hand and the dial was starting to develop "dial rash" or abrasions from a lack of a crystal.
The nice thing about my example is it also came with it's original bracelet.
With it all cleaned up and with a new crystal and hour hand, I think it turned out to be a great project watch. I'll have to try to find a slightly longer hour hand though I think.
