Recently I began wearing it occasionally, and it runs 8 sec/day fast. I haven't wound it since I bought it. It's been driving me nuts...

Sooo... what am I doing wrong? Do I really need to wind it? This was neve an issue with my 1986 GMT Master II...

Maybe you are doing something wrong when you are not wearing it. It will run faster if you leave it face up. It will run slower if you leave it on edge with the crown down. It will run even slower if you leave it on edge with the crown up.
