Found this vintage GP in my watch box in garage and it still works but after wearing I'm reminded WHY it was left there, it loses time CONSIDERABLY like a half hour. I assume it DEFINITELY needs servicing!

Before you spring the money for a service(which it probably does indeed need) you might buy a cheap demagnetizer on Amazon and see if that makes a difference or not. If not it never hurts to have one around for your other watches.

Thanks because it isn't actually slow, the second hand works but the time doesn't change!
