I would have to go with when you drop that balance in and it comes to life on its own..
the worst is finishing up a restored watch and as you rubbing off something on the train bridge with some rodico and your thumb hits the balance and you here a click and realized you just broke your balance staff... I walked away from my shop for a few days after that one..
Which of the following gives you the most ecstatic feeling? [emoji23]
o "One more turn and it's all in!" - winding the mainspring into the barrel by hand
o "Fourth wheel in... Third wheel in... Escapement wheel in... And they are all turning freely! Wee!" - aligning the train gears into their jewels
o "swing please... Swing please... Yes!" - installing and seeing the balance assembly swing into action
o "0s/day...0.0ms...270 degrees... Straight line... Not bad!" - after regulating the watch
o "Such a pretty watch!" - admiring the assembled watch head without strap on wrist while still wearing finger cots
o "You know what? I fixed this myself!" - telling your wife/children/friend your new hobby
o "I can watch all these videos all day!" - gets popcorn and sit in front of the computer to watch Mark's videos
From the little info I can find they were first produced in 1974, the one you have puts as a September 1975 model. Parts list Seiko 41A.pdf more parts are listed here: http://cgi.julesborel.com/cgi-bin/matcgi2?ref=SEK_CS^4100-6007
I have found this, so the method I used stem in setting position seems to hold some water.
A word from Mark our leader may clear this up or at least give us more (hopefully) confidence in the future.

Same for me !
Nothing is more depressing than doing all the dis-assembly, getting the parts fixed and cleaned, putting it all together and when the balance goes in, nothing happens...
I personally wouldn't worry too much. If your watches are in good condition and you service them every five years or thereabouts, the will more than likely outlast you without needing parts.
Best feeling...
'the click as the last pivot falls into place'
Worst feeling...
'the click as you tighten down the train bridge screw (means you've broken a pivot)'
'the 'oooHH sh!t' feeling when the watch you're working on hits your lap on the way to the floor'

I couldn't do without my Dremel but like George I always finish off by hand
(just realised what I have written - please resist lads I was actually trying to be serious for a change)

Influenced by Lawson's post 'Carl Zeiss - Eye Mag Pro' I bought a cheaper 6x 350mm pair of Galilean binoculars from China.
These are intended for dental use but any dentist trying to use a 6x magnification mutst have control of the head position far better than I can manage. The viewed object was wobbling by about 50% of the 45 mm field of view.
The optical quality is excellent and so I have turned them into a binocular microscope using a heavy duty flexible support with standard end pieces as sold for microphones.
Here in the bench mode with a Benson Aquatite movement - ample working distance.
The only work that was needed is shown: a support that fits firmly into the mike clip and a pair of eye cups with
adaptor rings to match the eyepieces of the binoculars.
Here mounted on my lathe base-board for some micro-drilling.
