Continuing their fine trade of turning wannabe designers' sketches into real watches you and I can buy, Tokyo Flash has plucked a Brit's idea out of the sea of wrist-furniture, and called it the Kisai Seven. Inspired by Tron, it may look like no watch you've seen before, but the dark patches on the inner and outer rings actually act as hands.

Simple really, once you see it. Though I say "simple" compared to other Tokyo Flash watches, of course. If you buy the watch in the next 66 hours (at the time of writing), Tokyo Flash will discount it to £63. Thereafter, it's a cool £87. [Tokyo Flash]
