I have a ladies pocket watch, gold in color, excellent condition, runs perfectly, not sure on the size, it looks about the size of a half dollar, about 1 3/16" diameter. It is clearly stamped J.W.C. Co on the inside, "warranted 25 years, crescent" with the # 202017236 on the inside of the cover. The workings are marked Elgin, 15 jewels, 16676692. It is not roman numerals, standard numbers, with a second hand circle where the 6 is. I am wondering about what year this is from? Thank you.
