Demonstrations of unlocking and locking the phone, as well as sharing contact details with friends via data written to the ring's memory are present in the video.
The ring is also physically shown for the first time, instead of the renders that had been distributed previously. However, the ring that the actor is wearing appears to be narrower than the ring shown in renders, so it's possible that it's merely a video prop.
Geak's ring will go on sale on the 8th of August.
