yes, it is true – apple watch is NOT water proof.
good luck with your fitness activities with a watch that breaks under heavy rain, sweat, or while drinking and moving.
i have NEVER EVER had a watch which is NOT water proof.
i was not even aware such things existed.
maybe in 1800s.
not water proof watch is like a car which does not go faster than 20 kmh only.
or like an airplane which can fly 300 meters only.
a not water proof watch!
