Bought a new 645M and wore it 10 days. Last night, it itched a little, but I didn't think much of it. Today my wrist is ichy, red and slightly blistered.
I shower with it on, but otherwise haven't washed it or my wrist, so I am hoping that helps, but I am afraid I am allergic to the band.
Any suggestions for a band? I wear it everyday and for running, worried leather will get sweaty, metal will be too heavy and everything online just seems really cheaply made.
