Nava Design clocks carry the signature of Nava's great graphics. These are the some of the most modern and, Fitz and Su think, the most interesting clock available. Nava clocks go beyond just telling the time. They can change a wall with their and create interest where there was none. The wall clocks are made of aluminum with a soft, textural paint. The desk clocks are painted wood with a smooth surface. All clocks are battery operated.
