Pam 372 second version stem

[LORRYQU]

Need a new stem and the watch maker is asking me what type of Chinese movement it is. He can't find the correct stem. Any help will be appreciated.

The truly second version (Angus maker with unblued screws and non-gold CP) only uses a standard A6497 movement with decorative plates. It would be better to post the picture of the movement so we can know what it is.
