Does the watch still charge if you connect it to your USB charging cable and an 20W Apple power adapter?
If your Apple Watch won't charge or it won't turn on - Apple Support
Did you try to force restart your watch by pressing and holding the Digital Crown and the Side button together for about 10sec, until the Apple logo comes back again?
