Pre SIHH 2014, A. Lange & Söhne unveils the new Grand Lange 1 Moon Phase that gives the exactly calculated to 122.6 years moon phase display a shiny appearance on the dial. A patented method of coating the moon's disk gives this astronomical complication a highly detailed appearance. The moon is a fascinating celestial body. It determines not only the tides, but also affects the rhythm of life of many creatures and plants. A moon phase display is therefore highly appreciated by many watch lovers.

Since its relaunch, the Saxon manufacture has presented twelve models with such a complication. However, never before the moon phase display has been so prominent as it is in the new Grand Lange 1 Moon Phase. The popular astronomical display received a large stage on the dial. You can now clearly see how the moon phase display follows the actual phases of the moon in a remarkably realistic manner because it is linked to the continuum of the hour. Thus, it is — just like the moon itself— always on the move and in such small steps that you cannot detect this movement with the naked eye.

In addition, the moon phase indicator represents the time from new moon to new moon with an accuracy of 99.9978 percent. 29 days, 12 hours, 44 minutes and 3 seconds , the average synod lunar months. For simplicity, the cycle is therefore rounded in most classical moon phase displays to 29.5 days. This leads per cycle to a deviation of 44 minutes and 3 seconds, which adds up after two and a half years to one day. The much more accurately calculated seven-gear on the Grand Lange 1 Moon Phase reduces the deviation per lunar cycle to less than a minute. Once set up properly, you would have to correct the display by one day after 122.6 years. With a corrector pushpiece between 7 and 8 o'clock on the case band, the display can be adjusted. The solid gold moon disc testifies the perfection claim of the Lange product developers. The result of extensive research and development work is a patented coating process that through an unparalleled color brilliance and sharpness of all the details meets the highest aesthetic standards. Due to interference effects —the superposition of reflections— all non-blue color components of the incoming daylight are absorbed. So is in the eye of the beholder an intensely blue color impression. The more than 300 stars of different size are cut so sharply drawn with a laser that they act like a miniaturized representation of the Milky Way .

With the combination of decentralized dial design, large date and technically advanced caliber, the Grand Lange 1 Moon Phase bears all the marks of the most famous family of watches from A. Lange & Söhne. The calibre with an impressive power reserve of 72 hours is only 4.7 mm thick thanks to the use of only one barrel. The case, available in yellow gold, rose gold or platinum has a diameter of 41.0 mm. With a balance spring developed and manufactured in-house, a three-quarter plate made of untreated German silver and intricately hand decorated parts, the Lange calibre L095.3 features all the classic elements of the timepieces from this manufacture.
