My watch is dead and won’t come back on. I have tried all the Apple suggestions

Has this watch been sitting for an extended period of time, without being used, and the battery was allowed to go completely dead?

If so, you will probably need to send it in for a new battery.

If that isn't the case, have you double checked your charger somehow?

Start at the wall receptacle... Plug a lamp into it. Does the lamp turn on?

Could it be the transformer that the cord plugs into? Can you take the charger cord to a computer and plug it into a USB port and see if the watch will start charging?

Do you have a friend that also has an Apple watch? Can you take the watch to their house and place it on their charger to see if it will start charging.

Same thing happened to my wife’s SE.

The battery died, she placed it on the charger and now it has not charged or turned back on.

it’s not the cable, I use the same one to charge my Series 6.
