Meteorite Shines in the New Platinum Luna Magna from Arnold & Son

Arnold & Son coordinates materials and complication on its Luna Magna Meteorite model. This high-watchmaking timepiece with a spherical astronomical moon is adorned with a sand-colored PVD-treated meteorite dial surrounded by a platinum case. To complete this limited edition’s cosmic references, the part of the moon in shadow is also made from meteorite. In a final harmonious touch, Luna Magna Platinum shines with a distinctive glow at night thanks to the Super-LumiNova coating on its moon hemisphere and opal subdial.

The ever-changing moon is an inexhaustible source of inspiration for Arnold & Son. And so, the largest and most-spectacular moon in the watchmaking cosmos begins a new cycle with Luna Magna Meteorite. With a satin circular-grained finish, the hour and minute subdial is crafted from white opal, a semiprecious gemstone known for its purity and delicacy and befitting of Luna Magna’s complication. The off-centered position of this display frees up the dial, which is adorned with a large sand-colored meteorite disc. At 6 o’clock, the three-dimensional moon is carved from the same meteorite and Cacholong opal whose properties lend it to sculpting. Lastly, the understated shine of the platinum case establishes the distinguished elegance of this limited edition of 28 pieces.

Moon Landing

Arnold & Son chose a meteorite from the octahedrite class that, once worked, reveals “Widmanstätten patterns,” which are instantly recognizable 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 different faces. The cool shine of the platinum is tempered by the iridescence of the meteorite and the milky whiteness of the opals. Arnold & Son selected these stones both for their moon-like porcelain hue and their properties, which make it possible to add Super-LumiNova – invisible by day but glowing blue-green at night.

Fine Craftsmanship

Luna Magna Meteorite is driven by the A&S1021 caliber, which has been fully developed, manufactured, assembled, and adjusted in the Arnold & Son Manufacture. This hand-wound caliber, 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 caseback 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 Meteorite's moon-phase 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.
