I just got a 976 that is a 5 digit serial number with the pendant set "detent" stem. I added the stem but do not have a case for it. My question is: is any case with a long pendant usable for this movement? Can you simply remove the sleeve and stem and use the detent stem? Someone will know the answer. I referenced this movement in Pitfalls and will add the link below.
