Good point, but after having gone through a Rolex rebuild, I can tell you that while they're tough, they won't run forever. . .without a Rolex certified jeweler. Don't get me wrong, after years of not wearing it because it would not stay wound enough to keep time (during which time I started wearing G-Shocks), I had mine rebuilt and it came back running better than new. However, it cost plenty and required new factory parts.

The Rolex waterproof is only good for the life of the seals DOHH, mine were 15-20 years out of cert and there was slight humidity damage to the face and hands. I have a feeling that all watches in this class need occasional TLC or they too will go TU.

Meanwhile, my Casio just keeps on keeping great time. $.02
