I spend the fifty or so bucks for a new ironman every two years ... and it lasts about that long.
In two years the face will be scratched up but the electronics work fine. Also, somewhere within two years the band will break and a replacement band is about twenty bucks by itself. If the band breaks that means a new watch for me.
So, the drawback on this watch is usually the band.
For the most part though, if you want a good, accurate, disposable beater watch, this fits the bill.
