Inspired by zippers, the watch body and face are made from aluminum, with a choice of black or silver, like Kisai Tenmetsu watch. Eleven black tubes rise slightly from the surface, like Kisai Keisan watch.
A sleek and interesting watch even when off. The five tubes on the left count the hours in binary — the top four, when lit, mean +1, +2, +4, and +8, while the fifth, when lit, means PM. The six tubes on the right count the minutes in binary, +1, +2, +4, +8, +16, and +32.
