Why can't I fit these 6497 hands to my 6497 mechanism? Please help.

This should be easy for someone in the know.

i have a 6497 with the standard rep canon pin and hour wheel.

I tried to put some 6497 hands on it last night, which I think were from Davidsen and they don't fit. It looks like this is because on the hands I have, there is little to no inner tube.

Do I need the canon pin fix to use these hands? I am guessing that these ones are for already modified watches. It seems to be because the hour wheel doesn't come far out enough above the dial for the hand to sit happily

What do you think - the inner tubes is almost flush to the second hand - maybe 1-2mm on the hour hands

Davidsen Hands are wider to be fitted on an H3 pinion., won't fit on H1

Thats what I suspected - thanks for the tip. I've got an H3 kit on it's way
