I don't see why the face wouldn't be reversible - it detaches completely from the strap, and it's not like the software UI is going to be upside down - your phone can already handle that. The only difference will be that the crown is below the button.
Agreed, it just seems like something that Apple ought to mention. Can't find it anywhere on their website. And orientation changing makes sense for a phone feature because people switch between portrait and landscape, while this is a permanent setting that 90% of people would never touch.
It'd be a giant oversight for Apple though, and I'd be surprised if nobody on their design team is left handed.
Yes, I would have also thought that since this was a presentation to the general consumer and not just a tech demo ala WWDC where these things don't matter yet, that they would have addressed this issue by showing a person taking the watch from one wrist and putting it on the other and thus showing the device can be turned around and used just like before.
