I started the latest software update this morning, but it appears that the watch has turned off and wont turn back on. My phone can't find my watch either. It was fully charged and on the charger when I started the update.

I started the new software update this morning on my watch. I left it for roughly 30 min and when I was getting ready to head downstairs I grabbed the watch and put it on (assuming that the update had run its course). About 10 mins later I noticed that the watch wasn't powered up. I then checked the watch app on my phone and it showed that that the watch was still installing. I put the watch back on the charger and let it sit for an additional 10 mins. The watch didn't respond to being on the charger. I had to leave for work and grabbed the watch and the charger to bring with me. The watch wont respond to anything and now the phone cannot find the watch either. Any suggestions?
