Jwl --
i am not a watchmaker and do not play on TV; fortunately i have a colleague that is -- his family for a few generations back were NYC jewelers -- and he does all my caseback-off work (thank you BrianG).
BUT, if you go for it, i am a photographer and please, pay careful attention to dust control. We have to do that now with camera sensors: every time you a swap lens you open the sensor to an ocean of tiny, tiny, bits of dust. Similarly when the caseback is off all those tiny particles can settle in your case and will be visible on the crystal or the dial if you are not careful.
Photographic sensor pixels are sub-3 micron now so we worry about finer dust than you can see. Nevertheless you can easily experience significant dust entry when working on the average kitchen table . . . even for a simple regulation, much less a movement swap.
