Hi All - looking for a 7017 movement tension spring that sits between the movement and case back. Not sure of the Seiko part number and assume this ring fits other movements as well.
EDIT: a little extra info. Doesn't seem to be any information on what the part number may be. Here is a picture of the ring. Outside diameter is 31.115mm. I have to think this was a shared tension ring across other models. Appreciate the help.
