The Lava Watch is also called the "faceless" watch. You can't tell it's a watch until you push a button and the LED numerals show thru the links of the band. It's pretty neat. It tells time, date, and seconds. But it only stays lit for about 3 seconds to conserve battery life. If you search for "lava watch" you'll find it available at a lot of place for just about $15! Seems to be a pretty great price for a techie watch.
