What is a Holocron?
A Holocron, short for Holographic Chronicle, is a construct in the Star Wars universe that the Jedi use to store knowledge and secrets of the force. A Holocron can contain an astronomical amount of data, but can only be opened by using The Force.
Alluding to this fact, the 'Force' Touch mechanism on the Watch seemed a perfect platform for this construct to exist in our universe. Upon 'Force Touching' the Watch screen, the user would be presented with random bits knowledge learned by Jedi Masters in the Star Wars universe.
