It's a cheapie with pushers that move subdials. Trying to help a friend out that dropped it and snapped the stem and lost the crown. If I can find a stem and crown for $10 then it gets repaired

If its a cheapie and the pushers move the subdials, and the chrono hand continually runs, then its a 21j.

I already gave him my PAM 104 on Asso

I realize that much, but then what 21J is it so I can get a replacement stem? I've come up dry looking for "21J" since it's generic.

From Ziggy:

 

 

But the majority of Asian automatic movements use standard Miyota stems, not all do, but I would say fully 90% are identical to the Miyota one.

 

Part number would be 401/8215 Miyota (double check the part #, I may have it mixed up).
