This clock is composed of 24 triangular pieces (3 different angles, 8 pcs each) that are painted with 2 shades of metallic blue (lighter and darker) in alternating order - this gives the dial a virtual 3D effect, as if the zigzag shape were made of a folded paper - same as a real origami. - Raw material: dial is made of 2 layers of 4mm birch plywood boards - Manufacturing process: the elements of the dial are laser cut from a 4mm birch plywood board, and painted with lighter and darker blue. The painted pieces are glued on the backplate in alternating order. As these pieces are distributed manually there are no identical clocks manufactured. - The movement: is silent (non-ticking), second hand sweeps around. It runs with 1 pc AA type 1.5V battery (not included in the package). Hands are made of white plastic. - Dimensions: diameter: 29cm / 11" depth: 3,3cm / 1" weight: 0,5kg / 1.2lbs This product is made to order, usual manufacturing time is ~1 week.
