Remember when you were a kid and you had a spy kit that had a secret covert message written in it, and the only way to decipher the message was by using a special colored lens?

Now you can have that same fun in the form of a clock. The hour and minute hands both have colored lenses on them to show the hidden, filtered numbers.

~ The minute hand has a green lens which displays the numbers in minute form (by 5's).
~ The hour hand has a red lens which displays the numbers in hour form (1-12).
