After updating to 1.0.1 my watch was never the same. It kept resetting its self for no reason. I erased all settings and content, nothing, it would still reset the watch every few minutes. When trying to pair with my iPhone it would fail and reset. All was fine until I updated. Battery percentage would also never change. Always stuck on a number. Took it the Apple Store. Luckily for me I was able to show them what it was doing. Sometimes the Watch would work fine for many hours. But most the time it didn't. Anyways I should have a new one in a few days.
