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.

    • If you've used properly fitting hollow ground blades for larger fasteners you know they can handle a lot more torque than a regular screw driver without damage fasteners.   The difference is so pronounced you just should not work on antique machinery/equipment with slotted fasteners without using hollow ground blades or you will botch up the fasteners. However, relative to the current debate, two things occur to me 1)  To get the performance noted above, the bit has be a very good fit in the slot.  My set has I think 85 or 90 pieces.  Without that selection and ability to find a perfect fit, their advantage pretty much disappears.    Is a watchmaker going to have a similar selection to ensure that perfect fit and futz about constantly checking microscopic differences in fit?  2) Performance is superior, but the metric is torque handling ability.  Does this even matter in watching making?   My limited experience suggest no.  otoh, if you are  regularly damaging heads of screws with taper blades than yeah, figure out how to get an assortment of hollow ground bits that work for you....but otherwise, why worry about it?   imo there is no debate to be had on what is superior, the debate is simply whether it matters given the torques involved. A young guy I know worked for Roger Smith for few years (talk about a learning opportunity!).....I'm curious on he was taught

    • yes sir, forgot to mention "cone shape",  the  ajuster is a good thing,  i have over tightened the staff in the past.  this one is "floating" almost 1/16 inch !   i decided not to tighten the staff.  it's back together and keeping good time. Thanks,  vin
