The Time Tower is one of the more unique desk clocks we’ve seen. It does away with the traditional clock’s hands for a rotating square of numbers. The ring of numbers rotates around the single hand rather than the other way around on normal clocks with rotating hands. Whatever number is lined up at the top of the clock is the current time (6 o’clock in the photo). You use the hash marks inbetween the numbers to determine the minutes. The clock measures a little over 8 inches tall and costs $19.95 from Convenient Gadgets.
