Here's a clever and marginally useful take on watch design: the Sand+Time watch combines modern technology with the hourglasses of old, displaying the passage of time with digital grains of sand as they "fall" down the LED screen. How does that tell you the time, you ask? Uh, actually, it doesn't — that's the stopwatch mode, for when you're cooking an egg or seeing if you can beat your personal best in the 100-meter dash, I guess. In clock mode, regular ol' digits tell you what time it is.

Although I'm sure the novelty of the Sand+Time watch would get old pretty quickly, I still want one. I especially like the thinning of the entire face/bezel where the neck of the hourglass would be — nice touch. Unfortunate, then, that Pavel Balykin's design is just a concept, with no price, release date, or hope of gracing the wrists of the world anytime soon. Maybe give the folks at TokyoFlash a call, Pavel. — Peter Pachal
