Woot.com is selling a National Geographic watch with these functions for $55 shipped. Go to the site and look for the "Skimaster" - NG702KSK. But do not delay, it may sell out. Other models have already sold out, and it's for today only (3/04/09).
Only thing I don't like about this watch is the yellow wristband... one with the black band is sold out. But it's a great price
so I can't complain.
on edit: Looks like it sold out as I was typing my post, sorry. But if anyone wants one, set up an ebay search, as people frequently buy things on woot and later try to resell at a profit. So you might find one at an attractive price
