Scope watch tells time using line-intersections on Cartesian grid

The latest crazy Japanese watch from TokyoFlash is called The Scope, and it reaches new heights of whimsical impracticality in timekeeping. A large LCD displays a Cartesian grid on which the time, accurate to five minutes, is displayed as the intersection of two lines (x axis for hours, y axis for minutes); to the right is a ring of four LEDs that give you the time accurate to the minute -- when two LEDs are lit, add two to the time-count, and so on.
