A. LANGE & SÖHNE PERPETUAL CALENDAR “TERRALUNA”
A horological masterpiece, the “Terraluna” combines inventiveness and de sign competence.

On the dial side of the 45.5-mm pink- or white-gold case, the watch stands out with the regulator layout of scientific precision watches. The movement side presents an innovative and useful orbital moonphase display that depicts the constellation of the earth, moon, and sun.
Beneath the characteristic Lange outsize date – the first one in a model of the Richard lange watch family, incidentally – two smaller apertures show the day of the week on the left and the month on the right 내니맥피 다운로드. Thanks to this arrangement, the calendar displays can be easily read at a glance.

The progression of the moon phases can be observed through the aperture in the celestial disc. In the constellation view, the position of the sun is occupied by the balance. On newmoon days, the dark moon stands between the earth and the sun. It appears as a bright sphere on the opposite side of the earth on full-moon days. Thus, the position and phase of the moon are indicated simultaneously. In the centre of the display, the earth rotates about its own axis once a day. It is daytime on the half that faces the sun, or the balance, and night-time on the other. The peripheral 24 hour scale provides a time-of-day reference for the northern hemisphere.
