I'm not a watchmaker, but I have done some work on my own pieces under the supervision of a skilled and experienced professional. My main problem is that some screws have incredibly narrow slots, such that using a screwdriver of the correct width is impossible. Of course a driver tip can be ground thinner, but then it becomes excessively fragile.

I recut my screwdrivers to hollow ground configuration and have ended up with lots of screwdrivers. I use an optical comparator (15X made by Peak in Japan) to measure the slot in the screw then a small head micrometer to measure the screwdriver. I try to find a correct fit and if I can not I will get out a new screwdriver closest to the fit on the large size and hollow grind to fit. I also bead blast the end of the screwdriver with fine grit glass beads so the driver maintains a good surface connexion with the screw. One can now buy miniature torque wrenches if needed for tightening small screws otherwise; I do what was done to tighten screws in the video.
