Hi, I was trying to find out how to slow my watch down, I've seen the posts about how some watches are gaining up to a minute a day...............well, I'm gaining seven hours in an 8 hour period. Whats up?.......................

Hi i would say that is very likely a balance problem.

As Tiger suggests, there is a balance problem. Most likely the balance spring has looped some of it's coils over on itself. This will require the skills of a watchmaker to sort out.
The worst scenario is that the balance needs to be replaced but the good news is that there is no shoertage of cheap donor 7005s out there.
