The nickel plated brass sundial compass w/ wood box is a reproduction of a sundial with an internal magnetic compass. The top of the sundial is hinged and a curved scale is used to set your local latitude angle. The magnetic compass allows the sundial to be oriented North. The sun's shadow cast by the sundial's vane marks the local time. The top of the sundial can lay down flat, and both the latitude scale and the sundial vane are hinged to lay flat for compact storage. The sundial measures 4" tall. A beautiful wood box is included for display and storage of the brass sundial/compass.
