A sturdy wooden box was typically used to hold and protect the valuable ship's clock. Early versions of these old clocks can be seen at Maritime Museums such as Mystic Seaport in Connecticut. Today we offer these authentic "box clocks" with a more reliable and accurate quartz movement. This modern quartz clock is made with high quality movement and then mounted in a beautiful solid wood mahogany finish box. It rests in a traditional polished brass ship's chronometer gimbal with locking arm. The 5.75" square box has polished brass fittings and is provided with a brass plate for personalization. The elegant instrument will be displayed with pride for years to come. The dial is 2.38", the box is 5.75" x 5.75" x 3.75" and it weighs 3lbs 3oz. It comes with complete instructions, a fresh battery and a lifetime warranty.
