If you are going to spend that much money, get a real watch that holds its value like a Rolex or Breitling. (a lot more than $800) but will outlast you.
Gimmick plastic watches are just junk. If you want a GPS buy a good handheld like a Magellan or Garmin. Dont misunderstand, its probably a good watch, just not worth the cash.
Anybody remember red LED Pulsars? First digital display, I think. Sold for $1200 and now can buy better for $10.
