This accurate quartz clock is powered by a single common AA battery. The 4 1/4 inch (10.8 cm) diameter solid brass clock is fully gimbaled with a solid brass gimbal set. The gimbal arrangement allows the clock to remain level even as the ship heels. The clock's face is 3 inches (7.6 cm) in diameter, and the hardwood case measures 6 1/4 inches (15.9 cm) square and 4 3/8 inches (11 cm) tall. The boxed clock weighs a rather heavy 3.4 pounds (1.6 kg) and is a beautiful addition to a nautical collection or executive's desk. The front of the felt-lined hardwood case has a brass slide clasp and the box's corners are strengthened with solid brass inlayed splines.
