Watch won’t turn on or reset

One day i had my watch on it was working fine as usual and then the next time i looked at it it wouldn’t turn on or anything. i’ve had the watch for like 2 years now and it’s never done that. i tried resetting it and everything but it still won’t come on. however i put it on its charger in hopes i’d see any sign of life but i got none but i’ve just be carelessly leaving it on the charger because i don’t have time to go to the store to get it looked at and i looked over and on the charger the apple logo came on slowly and then went away slowly like a breathing effect. I still cannot turn the watch on or reset it or anything.
