Gear S died after ~2 minutes at the pool topic

I went at the pool with my Gear S to test if IP67 works fine. Unfortunately after 1-2 minutes under water (but not constantly) watch simply died. Water was under SIM flap and was also in speaker hole. I put it in rice and it's dry now but it's completly dead... Is there any way to fix it or should I use my warranty (I hope they will accept it anyway)?
