this is a fantastic watch. i had a previous generation of ironman watch before and was so happy with it. didn't have to replace the battery in 5 years and the only reason i bought a new one was because the band was cracking. i heavily used that watch, and now this one. i am in a profession where i am constantly logging times, so i always have it on if i am awake. i have used this one for a little over 6 months now and the only useful difference in this one and the old generation's is that it has multiple alarms you can set. i don't use them, but it is a nice feature if you need to use multiple alarms. as with the previous ironman i had, i am extremely happy. you really can't go wrong with this type of watch, the only difference in the models is the color..... have fun! excellent product.
