This complex marine compass with captain's sundial is an exact replica of the original made thousands of years ago. In its basic form, any marine sundial is a simple instrument, largely unchanged since its creation thousands of years ago, and is known as the first scientific instrument. Like sundials, ancient compasses were the primary device that utilized the Earth's magnetic field. The top of this pocket sundial is hinged and the curved scale is used to set the angle of local latitude. A magnetic compass allows the sundial to be oriented north. There is a needle lift mechanism that protects the jeweled compass bearing during transport. The sun's shadow cast by the sundial's vane indicates the local time. The compass is used to determine location and the sundial shows the exact time of day. Our exclusive 2-in-1 compass and sundial will help you find your way and measure the time it takes to get where you need to go. Material: Brass and glass Overall dimensions: 4 inches in diameter.
