12 months & 3 Days. Dead Watch.

How's that even possible.  12 months & 3 Days and this watch is dead.  Garmin are going to send me a replacement, but it is very disappointing to spend close to $1000 on a watch and after 12 months i need to accept a 'refurbished unit'.  The watch had 80% charge, went to the beach, had a swim and by 11.30am it was dead.

I had noticed a lot of map updates lately, maybe the watch can't cope with all of this update activity.   Has anyone else had such a drastic failure recently?
