We all know that the watch has a hidden 'diagnostic port' but I think it's primary purpose is to provide a cabled means of flashing a new image to a watch that didn't complete update correctly.
On the other iOS devices there is a mode that will, with a button combination, start the device in a firmware mode outside of the OS that allows for image installation when connected to iTunes.
With the Watch we can't even connect it directly to iTunes it seems.
If there are severe issues with any upgrade then I wonder if it's really a trip to the Genius Bar (not particularly convenient for some) to hook up via the hidden port hoochemegigger or if the USB interface power cable offers some comms to kickstart a semi-bricked device...
