Retailer Tokyo Flash offers a number of bizarre and interesting watches, but topping our holiday wish list is the $159 Rogue SR2. The SR2 uses the gaps in concentric rings of LED lights to report the time. The gap in the inner ring specifies the hour, while the gap in the outer ring indicates the minute. Surprisingly, the SR2 is one of Tokyo Flashes easier-to-read watches; for hardcore esoteric timekeeping, consider the $99 Pure LED, which uses a coded set of flashing LED lights to represent three different units of time. But even if you give the relatively intuitive SR2 as a gift, be sure to include the instruction booklet.
Who it's good for: Your geeky friend who's never on time.
