Replica A. Lange & Söhne Grand Lange 1 Moonphase Watch and Lange is a long-time story. Since its restart, the manufactory in Saxony has presented twelve models with this complication. But never before has the moon phase been as prominently showcased as in the new Grand Lange 1 Moonphase.
The much more precisely calculated seven-gear transmission of the a. lange & söhne grand lange 1 replica reduces the deviation per cycle to less than one minute. Once correctly set, and assuming that the watch runs continuously, the display would only have to be corrected by one day every 122.6 years. Moreover, the display can be adjusted at any time by using the push piece embedded in the case flank between 7 and 8 o’clock, for instance if the watch has not been wound up for a longer period of time.
A spacious stage has been reserved for the astronomical indication on the dial. It provides a proof of how closely the moon-phase display tracks the actual orbit of our planet’s satellite. This is because the display is connected with the hour-wheel continuum. As a result, it is constantly in motion, just like the moon itself. The increments are so small they cannot be detected by the naked eye.
Additionally, the moon-phase display indicates the time that elapses from new moon to new moon with an accuracy of 99.9978 %. The average synodic month lasts 29 days, 12 hours, 44 minutes, and 3 seconds. For the sake of simplicity, most classic moon-phase displays round this cycle down to 29.5 days. The resulting deviation of 44 minutes and 3 seconds per lunation adds up to one day in merely two and a half years.
Combining an off-centre dial, cheap replica a. lange & söhne grand lange 1 moonphase the outsize date and a lavishly finished manufacture calibre, the Grand Lange 1 Moonphase features all of the hallmarks of A. Lange & Söhne’s timepiece family. The 72-hour power reserve was achieved with only one mainspring barrel. This is why the height of the movement is a scant 4.7 millimetres. The case in yellow gold, pink gold or platinum has a diameter of 41 millimetres.
