All clocks are lovingly "make-u-factured" by both hand and machine. A laser is used to precisely cut the acrylic or wood pieces and they are then printed in full color by a special ink-jet process. No glue or any type of chemical coatings are used. Finally, all parts are hand assembled and prepared for shipping. Made in USA and proud of it. Requires 1 AA battery (not included). Awesome 3D pop out effect. SILENT quartz pendulum movement. Approx 11.5"W x 12.5”H x 1"D (including pendulum piece). 1/8" thick laser cut baltic birch plywood. Original design by Paul Ocepek. Made in massachusetts, usa.
