I have made this adjustment on other pams. The case is design has a typical screw down tube, but then you would be left with a gap between the tube and the case. This hex nut fills this gap and sets the spacing between the crown and case. To adjust the spacing, you have to remove the crown guard and crown/stem. Once those are out of the way, you can adjust that nut by pressing it with your thumb and turning. I don't think you need a special tool, but I would suggest removing the the nut and putting a little silicon grease on outer threads of the tube. Screw the hex nut to your desired depth--but take care not to leave too much space you're going to have an issue with winding and setting time and date. I am frankly not sure why adjusting the hex would effect water resistance--you just have to make sure that the gasket on the bottom of the crown makes good clean contact with the hex screw and you should be fine (use a little silicon grease on that crown gasket as well while you're at it.
Will this affect the water resistance of the watch? I also want to fix the crown position....
