Every watch I ever sent for repair came back in worst shape than before I sent it. Once not only did they add new scratches on the piece, but they didn't even fix the problem I sent it in for in the first place AND the watch flooded on the first dive.
Well, now my Hydro is 6 years old. It run to perfection, in fact, it is the most accurate mechanical in my collection. But it is 1 year past due on servicing, and I will most probably scuba with it, which get me a tad worried about the sealing.
So, should I send it in, or wait that something goes wonker with it?
