I would not install this set of hands in any watch for 2 reasons.
1) Pitting/rust is an infectious phenomenon, if some rusty-dust
reach another metalic part of the watch that one will also start to corrode.
2) Your minute hand being of "tight waist" type it must be
radium lumed and that lume material is very fragile ask KO (sorry private joke)
looking at the lume material of your hand it is starting to crumble and you will soon find radium dust in the movement and in the oils (gumming effect).
