Automatic calibre and moon disc

The automatic caliber L086.5 was manufactured from 325 individual parts and contains the astronomical complication. The moon disk with 852 stars was connected to the hour wheel and is therefore always in motion. If a correct setting has been made, the actual position of the moon is displayed accurately. The moon phase displays of A. Lange & Söhne are much more precise than those of other manufacturers. The ingenious mechanism of the gearbox ensures that the moon phases are displayed accurately. The intense blue tone of the moon disc provides a special effect and ensures that the stars cut with a laser are particularly rich in contrast.

The Perpetual Calendar and the Big Date

The orbital moon phase display shows the position of the sun and moon and the display includes the sky disk, the moon disk and the earth disk. The position of the sun is determined by the balance wheel and the recess in the sky disc allows a view of the moon. The large date from Lange & Söhne is a date display that has been integrated into a wristwatch in this size. A golden frame frames the date, which is displayed in digits. Thus the reading of the date is quite simply arranged. Lange & Söhne employees are constantly facing new challenges in the development of new movements. This often results in completely new mechanisms such as the world's first triple rattrapante mechanism.
