I guess you have a point with the vacuum, however I've had my crappy one for many years and it has always done a pretty good job. Then again, I hate vacuuming and do it once a month maybe.
As for the Rolex, other watches may last a lifetime but the Rolex is much better built than any other automatic watch. As I mentioned, they can be used in ANY situation without fear of breaking. Very few other watches could be worn to a dinner party and also scuba diving. They also retain their value extremely well because the design doesn't change year to year. A $200 watch may very well lose more value over its lifetime than a Rolex because of this.
