I bought a Rolex GMT in 1982. It has not left and never has left my wrist since then. Shooting, swimming, hot tubs, showers, etc. The only time I take it off is if my arm won't fit in a small work area with it on like working on a car. It has had a clean/lube twice (NOT by the Rolex people) since then and still keeps perfect time. Would I buy another one?? No. But, I am sure as hell glad I have this one. I bought this one as I was going through watches of every kind on a yearly basis.
