For those types of use you don't need to screw them down, just leave them unscrewed. Screw down pushers are a safety feature to avoid inadvertent operation of the pushers under water and so they only need to be screwed down when swimming / diving.
Thanks Roff, but now if I left them loose, would they be more likely to be damaged if I bang my watch against the edge of a wall or something? I tried it yesterday at an AD but didn't really noticed if they moved a lot when loose. The nice salesman told me the same thing about leaving them loose and that there are gaskets already to prevent dust from getting in.
