(English) Design submitted by Logan from the USA.
This watch design looks like a metal ribbon with randomly oriented C-shaped holes, some pointed up, some left, some right, some down (four directions, hence the name Quad). The orientation of the 33 C-shaped holes has been carefully chosen so that the four digits of the time can always be displayed using two C-shapes per digit. LEDs shine through the holes to show the digits. The style is like Shinshoku or Fire, but you don’t have to do any math or counting to read the time.
There are extra C-shape holes continuing around the band, in addition to the 33 used to tell the time. The extra holes do not light up, but make the pattern continuous.
