M,S,S. is an acronym for Maru (circle), Sankaku (triangle), and Shikaku (square).
It is a clock where the numbers on the face are represented by circles, triangles, and squares. When you combine these geometric shapes, they begin to look like numbers. The shapes that indicate the time are rhythmically arranged to create a new design clock.

The clock is available in monotone colors each with a slight tint of color and a deep finish.
