Antique Brass & Copper Sundial Compass, Sundial Clock in Leather Box Gift Sun Clock Ship Replica Watch

A sundial compass is a fascinating combination of two ancient navigational tools: the sundial and the compass. It's a unique and practical device that allows you to tell both the time and direction, using only the power of the sun and Earth's magnetic field. The sundial portion usually consists of a flat surface marked with hour lines. A thin rod or triangular plate called a gnomon casts a shadow onto the surface as the sun moves across the sky. The position of the shadow indicates the time of day.
