My Apple Watch went offline

My Apple Watch went offline and I turned it off then on again. Nada didn't work. Showed it was okay on my phone so I turned both off then on. Still didn't work. I went into my phone and unpaired, got an error it didn't unpair correctly and gave me instructions on how to do it by going into settings. When I went in to do that it did unpair from my phone, but my watch is still showing the apps and everything and is still offline. When I try to pair it, it doesn't pick it up in the camera and won't let me do it manually. Does anyone have a suggestion? It's a 38mm sport watch I have had 3 to 4 years and have never had a problem. Any help would be appreciated. Still showing offline and no lights in the back as it normally does.
