My Garmin Fenix 6X Pro failed only after 2 years of low to moderate use. Customer service wants to charge $190 for a replacement. The watch flashes the blue triangle then the Garmin sign non-stop. I tried everything in the forums and nothing helped. Garmin express also didn't recognize the watch.
If you're in the market for a Garmin, don't buy it. $900 for a watch that fails after 2 years is outrageous.
