Eight mother-of-pearl sectors light up on a dark background and accompany the wearer during the first few hours of the day. It is an artistic representation of how the sky appears at that time of day. If the hand is located at 5:30 am, it moves in the nightly dark blue. The colors change little by little, until the day finally starts around 9:30 am with a bright white mother-of pearl sector. The black and white striped hand shows the time the alarm will sound. Manually wound, this miniature alarm clock is louder that you might expect. A very cool piece! Limited to only 100 pieces.
