Just how much torque do you think you need to apply?
The proper way to hold a watch screwdriver is with the middle finger and thumb hold the barrel and place the index finger on the top "swivel head thing." That is all the torque necessary to tighten a watch screw.
If you have an extremely tight, corroded screw you must remove this grip can be used. But never tighten a screw with it, you'll wring the heat right off.
