Arnold & Son
Luna Magna Platinum
1.LMAX.Z01A.C233C
Arnold & Son coordinates materials and complication on this Luna Magna Platinum model. This high watchmaking timepiece with a spherical astronomical moon is adorned with a sand-coloured PVD-treated meteorite dial surrounded by a platinum case (Pt 950).

Arnold & Son chose a meteorite from the octahedrite class that, once worked, reveals “Widmanstätten patterns”, which are instantly recognisable for their jagged criss-crossing structures. The PVD treatment in a grey-beige shade reminiscent of stardust brings out the striking geometric motifs, creating a sense of harmony with Luna Magna’s astronomical complication.
The various materials catch the light and give this timepiece multiple different faces. The cool shine of the platinum is tempered by the iridescence of the meteorite and the milky whiteness of the various opals. Arnold & Son selected these stones both for their moonlike porcelain hue and their properties which make it possible to add Super-LumiNova – invisible by day but glowing blue-green at night.
Luna Magna Platinum is driven by the A&S1021 calibre, which has been fully developed, manufactured, assembled and adjusted in the Arnold & Son Manufacture. This handwound calibre, which has been designed with the lunar globe in mind, features a 90-hour power reserve and a regulating organ oscillating at a frequency of 3 Hz. The movement includes a secondary display detailing the age of the moon on the case-back side. Its clearly readable markings are designed for high-precision adjustments.
The sophisticated mechanics are also based on precise astronomical reality. The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. The Manufacture has managed to replicate it in such a way that it will take 122 years for the movement’s display to deviate from the correct celestial reading by one day. The correction required at this time will be easy to make, as the Luna Magna Platinum’s moonphase function can be accessed directly via the crown. This practical feature has been made possible by Arnold & Son’s total mastery of the watchmaking process.
