THE MOVEMENT – CALIBER I I I | 37 DECLINATION – A NEW INDICATION 23.5° North latitude Equator 23.5° South latitude The indication of sunrise and sunset and the equation are well known. It is the changing angle of the sun’s rays onto the surface of the earth that forms the basis of these indications. The inclination of the axis of the earth to the ecliptic of 23 degrees and the orbiting of the earth around the sun are the causes of the sun’s rays impinging sometimes more on the northern hemisphere, sometimes more on the southern hemisphere. For the first time, LANG & HEYNE has made it possible to indicate directly the degree of the sun to the equator. The earth disk which oscillates during the seasons is controlled by a program disk where the value of the degree of the declination is accurately stored. POSITION JUNE 15th summer on the northern hemisphere POSITION MARCH 21st OR SEPTEMBER 21st equinox POSITION DECEMBER 15th summer on the southern hemisphere
