This is an Elgin Pocket watch that still works.
The back plate comes off and on the inside of it there are machined-engraved markings: "Brookline guaranteed 14 karat golf filled". It includes a number "4567000"
There are also some hand-engraved numbers as well:
On the back side of the watch itself, it says
"Elgin National Watch Co. USA"
