Apple watch constantly restarting

I have a series 1 apple watch which over the past few days will not stay on; it keeps restarting. It needs a software update but it will not stay on long enough to even begin the update. I tried to factory reset it but once I put in my password in and accept that I do want to reset, it just sits there as if I said cancel. It never actually resets. At one point I was fast enough before a restart to get my watch to begin downloading the new update but it restarted and then the update download was frozen at whatever percent it was at. I have let the battery completely drain and tried again; no luck. I had my watch connected to my phone and tried to push the update through that way, but the watch didn't stay on long enough to even download it. I have gotten errors on my phone when trying to update the watch saying it needed to be at 50% and connected to the charger (which it was), that it was unable to connect to the watch (which it said on bluetooth that they were connected), and just that it was unable to do it. Any help on this would be awesome! Thanks! :)
