Binary Shinshoku LED Watch Design
This watch design is a continuous-band watch like Tokyoflash Fire or Shinshoku, but the pattern of the holes/LEDs is essentially a binary tree. This makes it easier to read the minutes by comparing to the obvious locations of minutes 2, 4, 8, 16, and 32.
In the “how to read” illustration, you can see that each row represents a minute written in binary, with holes/LEDs in place of 1s. If the rows counted the minutes 1-59 from bottom to top, the watch would have to be too narrow, so instead, most rows are used for two different minutes, depending on whether the left-most LED (32) is lit. The hours are not written in binary, but simply counted 1-12 near the top left.
