The line of ceramic wall clocks started its life at around February 2003 as a proposition of five different faces.

The Udu drum is a pot drum made of clay and played with either the hand or a foam paddle. It has derived from a carrying water vessel into a percussion instrument after a side hole was added.

The Udu clock is an adaptation of the pot-drum. While the hole in the Udu drum is used for sound, in the clock it serves to show the hour, thus "ringing a bell" to chime clocks. The link between the two objects is also kept by the choice of ceramics for the clock's construction.
