We've always been a fan of watches with unconventional ways of telling time, and Tokyoflash's Heko is no exception. The top and bottom rows each have four LEDs aligned for their analogous analog positions -- 12:00, 3:00, 6:00, and 9:00 -- and two lights in between to indicate one-hour / 15-minute intervals, respectively. The four diodes in the middle are used when the minutes aren't a multiple of five. For example, in the picture above we've got (from left to right) 1:37, 1:43, and 10:13. More instructions are available on the product page. Made from solid stainless steel and weighing in at 140 grams, it's available for 9,800 yen ($109) and comes with white, blue or multi-colored LEDs.
