The Swatch Musicall is a Swatch with an extra alarm clock function. All the functions work with only one button. The first alarm melody was composed by Jean Michel Jarre, later followed by Phillip Glass. A second version came with a new seven tone technology, composed by other famous artists like Paulo Mendon?a, Nam June Paik, Peter Gabriel and Candy Dulfer. Swatch Musicalls were produced between 1993 and 1998.
