Vintage rolex hand corrosion - decrease value or no?

[Jayrock26]

Hello,

I am looking at a 5513 from 1982 and i notice some corrosion on the hands, dont know why this bothers me. Maybe because its creating spotting on the tritium lume. Instead of sticking to just the steel.

Is this something that i should avoid or is it just a part of buying vintage rolex?

What is considered a normal amount of corrosion when it comes to the hands?

Thanks!
