The idea is that you never have to adjust the hands of your watch anymore. Once you travel to another timezone, your phone (and so LunaR) will reorganize this. Once you press the lower right key, the time of your local (current) timezone will show up through the embedded LEDs.

Example: if 11 o'clock; the LED positioned at 11 will blink once (hour), and the LED positioned at 12 o'clock will blink twice (minutes).
