Thank you. The back is simply engraved with my grandfather’s name and his company’s name, “31 years ,” and “1973.” But now I see that the bracelet says “14K G.F.” and “STAINLESS STEEL HINGE.” So, that answers one question (thanks - the eyes aren’t what they once were). The bracelet also says “1-73” and I found a tiny “110” in two places, near the watch body. I suppose that one like this, in it’s box, might be valued at $500 or more.
