The Woodchart Santa Barbara Wood Clock is made from precision laser cut and etched Baltic birch. The water area is stained blue/green and is recessed 1 layer below the land and islands to give a dimensional look. The lakes show water depth contours with soundings laser etched on each contour. The clock face shows precise shorelines, highways, landmarks and lettering. Special finishing techniques bring out the natural grain of the Baltic Birch. The clock is powered by a single AA battery.
