I've found another old family watch, this one was my Grandfather's Grandfather's.
I know zero about pocket watches but I have this one and an Elgin Gold plated half hunter, this one is 'white metal' (whatever that is) it has no markings on it that I can see.
Inside the case back it states " WARRANTED PURE WHITE METAL" then
* SWISS MADE* below that inside an oval, inside the inner case it just has 8200 at the top of case with 7288 at the bottom with 12 below that.
There are 'jewels ' visible from the back of the movement but only about 3 / I can make out easily, it is key wound(original key) and runs very strongly and keeps fairly good time.
Not concerned about the value but I am guessing its not alot I would just like a bit of information about the watch though I guess there were thousnds made like it if not milions.
