Yeah, waiting for watchOS 5.1.2, but stable is critical since you can't restore it like you can with an iPhone, iPad, Mac or Apple TV.
Actually you can - if you have an ibus:
At about 2:25 in the video look closely at itunes when he plugs his apple watch into his computer.
itunes changes to reveal a hidden feature of itunes ability to do a complete restore of the apple watch, just the same way it can restore ios and apple tv devices.
He then proceeds to do the complete restore of the apple watch.
