Zen Clocks are made with a Japanese quartz movement and measure 8" high x 11" wide x 3" deep.
They run on 4 "C" batteries (not included). Average battery life with everyday use is about 2 years.
Each Zen Clock's 'E tone' chime has been hand-tuned to produce the same tone as the tuning forks
used by musical therapists. The 10 minute chime progression sequence follows a "golden ratio
progression." Zen Clocks come with a 40 page booklet detailing their many uses and their
harmonic design. Zen Alarm Clocks are designed in Boulder, Colorado, and made in
Shen Zhen, China; they include a 1 year warranty and a 30 day money-back guarantee.
