Arnold & Son Luna Magna Red Gold Blue Meteorite

Arnold & Son Luna Magna Red Gold Blue Meteorite

Reading Time: 3 minutes

Midway between Mars and Neptune, between warm and cool, the colour scheme of the Luna Magna Red Gold Meteorite evokes the sky, fire and the stars. Its three-dimensional moon-phase complication gives it an astronomical feel, the 44 mm red gold case a terrestrial side, and the blue PVD-treated meteorite dial a stellar dimension. The largest of all moons receives a rare and precious new interpretation in dynamic hues.

With contrasts between its shades, materials and perceptions, the Luna Magna Red Gold Meteorite is brought to life by the oppositions, symbols and energies of its fundamental components.

The subdial displaying the hours and minutes has a milky, almost lunar sheen thanks to its surface in opal, a semiprecious stone prized for its white colour, whose delicacy perfectly complements the unique complication of the Arnold & Son Luna Magna Red Gold Meteorite. The spacious dial, freed up by the structure of this display, is made from a large disc of ferrous meteorite coloured blue using the PVD process. The warm glow of the red gold, which contrasts with the midnight-blue dial, completes the precious and understated look of this limited edition of 38 pieces.

Endless details

The meteorite’s criss-crossing, jagged geometric structures, which are known as Widmanstätten patterns, reflect the light across a vast surface reminiscent of the Sea of Tranquillity. In no way concealing their depth, the deep matt blue PVD treatment instead subtly reveals them to those who know to look for them. The moon, a sphere formed half from Cacholong opal and half from blue PVD meteorite, reflects the nature of the celestial body.

The way these textures catch the light, its rotation controlled by an exclusive complication, makes this an ever-shifting timepiece. All the more so as the opal half of the moon and the subdial are coated with Super-LumiNova, only revealing their blue-green glow – invisible by day – once night falls.

An endless mechanism

Luna Magna Red Gold Meteorite is driven by the A&S1021 calibre, which has been fully developed, machined, assembled and adjusted in the Arnold & Son Manufacture. This hand-wound 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 also includes a secondary display detailing the age of the moon on the case-back side. Its clearly readable markings are designed for high-precision lunar adjustments.

The sophisticated celestial 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 and Arnold & Son 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 Red Gold Meteorite’s moon-phase function is directly accessible from the crown. This practical feature has been made possible by Arnold & Son’s total command of the watchmaking process.
