In what way did it die? it may be easily repairable. e.g. the common display issue on the old Pebble models was resolvable by just placing a shim behind the display so the data connection stayed solid.
A key criteria for the replacement was "I never want to have to think about whether something will break it" and the Instinct has lived up to that. Have spent the last few years wearing it surfing, snowboarding, through many bush fires and one structure fire where I forgot to take it off before donning. Hasn't skipped a beat.
