Hi there! I've found a gold Harvel pocket watch while moving furniture out of a friend of my family's house. The house was build and bought in the 1920/30s-ish. I don't know any about watches at all. So I'm looking for help with time period placement and opinions on worth. I'm using it as 1800's reenactment piece ;) I can't open it, it doesn't work. Do you all need anything else? It looks to be gold, I'm guessing 1940's from what I've seen online, though it looks like it says Swiss ant the very bottom of the face. No jewels or anything fancy, just a seconds time keep also, as you can see from the pictures. Also at the end of the gold chain(I'm guess 14k) it has an odd pocket knife. One ends a knife, and the others a... fish scaler? On the side of the "scaler" which is ribbed on the 'blade' part like a file, it reads "stainless", as does the base of the knife. I'm asuming the 'tabs' I've also circled are for opening it? Thanks gang for any help!
Can I take the backing off myself, or do I need a tool? Does it run on a battery?
