Topical! I have just got off the phone with Garmin. The watch casing on my Forerunner 645 music got damaged (where band pins connect) while helping my daughter out of an inflatable Swim ring. I was a bit surprised at this as didn’t think much force was involved. A bit of googling turned up it was a known weak point.
Garmin CS said the could replace for a reconditioned model at the cost of £117 (due to being 5 months out of warranty). I asked if they would they give me a discount against buying a new watch direct through them, but after asking his supervisor they said no.
Bit disappointing but now got to weigh up if want to pay for reconditioned model or look for any good deals on something else.
