Ok I am so new to learning about pocket watches and so far it is very interesting. My dad bought a pocket watch today at a moving sale and came across a Elgin hinged 17 jewel gold/gold plated pocket watch and I was wondering how to get information about this watch like how do we determine what a grade is and size and other things like that. We are clueless as you can tell. It is hinged and has the serial number of 16120046 on the back of the watch, not the case. Where did this watch come from and is it a remake? Help....Thanks for any information given.
