11 Color-Changing Watches

Forget about looking for the vertical hour and minute hands on your watch face -- these color-changing watches bring about a new way to tell if it's lunchtime. Instead of numerals, these chromatic timekeepers use a spectrum of colors as a new way to tell time. If you're used to associating 12 o'clock with "lunchtime," you may have to get used to interpreting "red" to mean it's time to eat.

These watches might not be the optimal choice for someone who needs to keep a tight schedule, but some of these designs are able to artfully communicate what time of day it is. For example, Ryohei Yoshiyuki's 'Time of The Sky' watch "tells time" by shifting from shades of baby blues, to the pitch black of midnight throughout the day.
