Hi there.
Have just had this watch replaced by Garmin for the fourth time. It's the same issue every time : screen goes completely blank during swim and the watch never responds. Just interested to hear any thoughts.
Have several friends who have it experienced any problems. Initially thought I may have been the wall charger but this appears not to be the case.
I wear the watch on the inside of my wrist (it faces inside my arm) can possibly be the only thing I do that nobody else does. Hard to say how this may cause failure other than pointing to a pressure/water proof issue.
Just to be clear, I am a professional who lap/ocean swims, rides on rollers and runs outdoors. Have owned many watches over two and a half decades of ironman tri (Mainly Polar as I was once sponsored but their product quality dropped about 10 years ago).
Interested to hear some genuine thoughts. Sadly Garmin have never replied to my questions as to what they've found in their testing of my failed units.
