A&S1512 – Astronomical Moon-Phase
On calibre A&S1512, a secondary indicator allows the moon-phase to be adjusted quickly and precisely. The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes, and 2.8 seconds. Arnold & Son has succeeded in representing it in such a way that it would take 122 years for this movement, if regularly wound, to accumulate a day’s difference between its display and celestial reality. Like all Arnold & Son movements, the A&S1512 calibre has been entirely developed, manufactured, decorated, assembled, adjusted and cased at the Manufacture in La Chaux-de-Fonds.
