Inspired by the 1975 "Berlin-Uhr" by Dieter Binninger, this watchface has a different way of telling the time. 
Each segment in the top row represents five hours, the segments in the second row count the hours. The third row displays five minutes per segment and the last row shows single minutes. 
Add them together and it gives you the current time. Allow a week to get used to this elaborate system.
Let your inner nerd fly!
