I dunked my SM-R800 watch in sea water picking up.my grandson. It then stopped working. On close inspection I saw that the heartrate monitor glass was cracked. I arranged for a repair with Samsung. the watch is only 18 months old so still in warranty. O am now told it isn't covered under warranty because of damage I have not caused. I have not put any pressure on the watch or dropped it. So much for being Military 810G certified. it doesn't even last the warranty period under normal use.Samsung want £49 to repair the glass, but the watch probably would not work due to water ingress. Others have had the same issue withthe glass. This looks like a design flaw. Not a happy. Samsung customer. Don't buy this watch
