Airplane mode on Apple Watch, by default, mirrors the setting on your iPhone. When you disable Airplane mode on your iPhone, it can not be mirrored to Apple Watch, because the radios on the watch are turned off. You need to disable Airplane mode on Apple Watch manually by using the interface on the Apple Watch.
