"Hello Kitty M766" is an iconic Citizen musical motion clock sold exclusively in Japan alongside countless other Sanrio and Hello Kitty-themed timepieces designed and produced by Rhythm. After its release in 2000, this charming clock became a best seller and different variations of it would continue to be produced for nearly 20 years. At the top of the hour, Hello Kitty's colorful trains begin to rotate around the dial as one of 12 children's songs play. The cute animals underneath the hands on the dial sway back and forth continuously.
