The hands ride on the cannon pinion, which is friction fit over the center wheel shaft. The cannon pinion has to be snug enough so that the hands move with the center wheel, but it also has to slip when the time is being set.
The cannon pinion often has to be tightened a little after a watch is cleaned. Unfortunately, now I have to start the testing cycle all over.
I also went ahead and tightened the second hand. Its fit was OK, but since this it a lever-set watch it's a good idea to make sure it won't get knocked off easily.
