Released in 2010 from the original design of Yuichi Nara, the MONO A and MONO B are minimalist clock timepieces based on a single design element— a black line.
 
The black indicators and hands are arranged, with some comfortable tension, in the blank white space within the round frame. The MONO Clock quietly tells the time and fits well in a simple, modern space or on a white wall.  Available in Model A with 4 numbers and in Model B without.
