I didn,t see where the remaining part of my post fell off the wagen, here we go.

Nicklesilver says 72,  dose that includes the variant 729? Very close in the family though.

To release the stem you loosen the lower one of the two screws by the stem.
I attache a service manual to the 72 but unfortunately with the wrong complication but in the 60's the tech sheets didn't always be the best.  ;) 
If you need more help it's better to continue in an other thread.

Nivada:  The 30 mm mvt. is out of the case and stem "set in place".   you might notice,  i had to remove one of the levers to get a straight shot at the secont case screw.   i'll replace it and move on to cleaning.  vin

    steping back from a complicated mvmt. repair;  i opened  a 1950's west clock wrist watch.  German made case and US mvmt..  it has a very unique stem set lever.  one of the 4 scews holding the back plate holds a lever attached to the stem set pin.  vin.
