Hey guys. Please help me find a stem or to retrofit one for the rotary skeleton watch I found on eBay. It says Japan on the dial. No numbers on the movement nor the back case. Bought this as a lot for repair or restoration project. Am new to the field. Found watches and restoration of them very interesting and enjoyable for myself. At least put a picture of the stem or a similar movement i can find a stem replacement. Attached pictures of my actual watch and a similar watch Found in eBay. Thanks in advance.
