I've received a new watch from Apple as the back kept coming off my last one - all good, except I cannot pair the new watch to my iPhone 6. It says it needs to update and then I get the message that WatchOS 1.01.1 Uour software is up to date. The phone screen then stays on this screen and the watch is stuck on the apple screen. The phone then keeps checking for updates, but nothing happens. I have tried hard resets of each but still no luck. Any ideas please? I am still on iOS 9, but can't update to watchOS 2.
