This precious ring is made of brass and acid etched.
It is an equatorial type sundial and is made up of a circle that represents the Earth's equator and a central bar that is the representation of the Earth's axis. Conveniently tilted to counter the inclination of the earth, the shadow of the bar marks the hours on the inside of the circle. This is a reproduction of one of the equatorial clocks that were made in Renaissance Italy in the 16th century.
It is universal and can be used interchangeably in any of the hemispheres by changing the measurement scale.
It is presented in a wooden box decorated with astronomical motifs, perfect to make the perfect gift and is accompanied by a small brochure with instructions for its use.
