I owned 2 Rush watches prior, both batteries died and I have never successfully changed a watch battery, so I bought the Marathon...I love the watch as it's just like the Rush in features, very easy to program, but the band is way too long for me.  I have to set the band on the smallest hole for my size wrist, which makes the watch sit awkwardly on my wrist due to the band length and hardware.  Timex should have stuck with the Rush band design.
