always grab the hands from the sides and not top and bottom to keep from scratching.
set down the dial protector, set your hour hand over the hour wheel stem, gently push on it with your handsetter. If it doesnt go on when your gently applying pressure it might not be alligned properly, never force it you will bend the hands. test to make sure you have the right size tip to go over the minute stem.
Once that is set, set the time to 12, apply the minute hand directly over the hour hand (I do this for perfect aligning because its the only time that looks bad when not perfect) press on the minute but don't get to close to the hour, the top should be set the same height as the cannon pinion
check the level from dial and hour hand
the second hand can be put in any position and it's the hardest one to get over the stem
