Our Take

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). 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 Platinum. 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-centred position of this display frees up the dial, which is adorned with a large sand-coloured 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.
