This watch displays time in a random, yet interesting method.  The display could also be configured by the user to always fill in the hours in the same way, i.e. if there is an available node to the left, it will always take that path until the left half is full, which could also be a way of showing AM/PM.  The watch could fill to the left during the AM hours and the to the right for PM.

The hours are displayed by dots in the top tree, each time the hour ticks over, a random path is taken within the tree, resulting in the hours never displaying the same way twice.  The bottom tree displays minutes in subsets of 15 with a +30 minute marker in the middle.  Just count up the bottom dots and add 30 if the middle dot is on.  Minutes fill the same way every time for ease of reading.
