7T36 "Age of Discovery": How to remove movement?

[mw210461]

I own a Seiko 7T36 (Age of Discovery) and need to get to the watch face as one of the eight (!) hands fell off.
Now this is desperate as I am no orologist, just a brave engineer.
Poor eyesight (-10dpt) is an advantage here, I have microscopic view, just no clue!


Before I have to give up on this marvel of engineering and auction the beauty off on the bay:
how to remove this movement from its gold case? The 7T36 has TWO stems and THREE push buttons...


I can open the back and do have the service manual which surprisingly does not mention the needed steps to get the movement out.
Thanks for any hint, eg. if to pull the crowns into specific positions, what levers to push, what to do with the button controls etc.
Now WHY the hour hand in the subdial fell off is an entirely different story...


I have two models of the 'Age of the Discovery' series, the minimalistic 2 hand and this complicated 8 hand version, and of course the big one let me down. Below a shot of both, before the right one gave up.
Thanks!

I haven't had one of these on the bench.  Looking at the tech sheet:
 

• Pushers are retained in the case by c-clips and are not mounted into the movement (normal for chronos), and do not need to be removed.
• Case back, caseback gasket, case ring, and antimagnetic shield have to be removed (they may pull directly out...sometimes Seiko an Citizen have snap or firction clips which hold them onto the movement).
• This should expose access to the points on the set levers for each of the stem, that when pressed (with a 0.5mm screwdriver or needle) toward the dial side, should permit removal of the stem...ususaly this is done with the stem in the operating position...if not, it is normally noted in the tech sheet.  You can actually see the two points you push to remove the stems on page 15 of the tech sheet.  Make note of which stem comes out of which position...they may not be the same part or lenfth.
• The movement may be held in the case with tabs and screws...but probably not.  If not, you should be able to place a piece of pith wood on the back of the movement, invert it, and gravity should drop it onto the pith wood.  However, frequently I have to coax Seiko movements out with a small screwdriver or dental tool. 
• Don't touch the dial--it will make you very sad....
• Tweezers and a steady hand to replace the hand.  And light pressure with the butt of the tweezers to friction it into place.

  Then you have to recase the watch...which is essentially the reverse procedure...starting with the movement, dial up on the pith wood, then carefully placing the case onto the movement, without banging dial or hands and noting that the openings for the stem match those on the case.  Then you can flip the case/movement over, re-intall the stems, etc and you're done.
 
Note that a flake of skin, lint, hair, dirt can stop any one of the four trains in this movement...so you need to keep it clean.  Good luck.

Thank you so much for the info - highly appreciated !
Indeed the PDF file shows some details on the stems on page 15. 'Operating' position is the OUTMOST position (each stem has two stops on this model)?
Will stems auto-snap into their position when pressed back into their location or does one also need to push these tiny 'brake' levers when inserting the stems into the case?


A 7T36 is probably not the first choice for such diligent fiddling for a novice - I shall do my very best.. if it just wasn't my favorite watch.
Thanks again!
