I cannot think of a worse way of updating the Apple Watch as the method Apple have chosen. It takes hours to download an update and then transfer it to the phone. It is beyond stupid. And I believe that many Apple Watch owners will never update their watches unless it auto-downloads in the background - which it doesn't. The way it should work is that the watch directly connects to WiFi and download the update directly. Android Wear is significantly faster with its updates and does auto-download. I love my Apple Watch but the update process is from hell, it is by far the worst experience Apple could chose.
