Xavier has found a way to control the watch in a new way, and rather than hiding the buttons, he exaggerated it to be more expressive and provide easy functionality.
24-hour day is divided into 1,000 beats, and this watch concept also includes alarm clock and date functions. It appears more mechanic with all options clearly exposed. It uses the decimal time used in lots of science fiction materials, such as The Naked Sun by Isaac Asimov, Metropolis by F. Lang, Battlestar Galactica, and French Revolution.
This design is for the unconventional but practical people.
