Arnold & Son is now offering the Perpetual Moon 41.5 Platinum in a limited fern green version of 28 timepieces. Its hue is inspired by the unique colour of the fern, an undergrowth plant found in abundance in the English gardens of Cornwall, where John Arnold was born. The “Stellar Rays” finish enlivens the dial with a sophisticated shimmer. Realistically depicted and set against a grained sky with a midnight-blue PVD treatment, the large white mother-of-pearl moon is also overlaid with Super-LumiNova. The moon is surrounded by Ursa Major and Cassiopeia, both hand-painted and overlaid with luminescent material. On the case back, a secondary display of the phases of the moon allows fast and accurate adjustment of the moon age. The manually-wound A&S1512 calibre that powers it is able to track its phases with exceptional accuracy. Like all Arnold & Son’s movements, the A&S1512 calibre was entirely developed, produced, decorated, assembled, adjusted, and cased up in house. This calibre uses two barrels and has an oscillation frequency of 3 Hz, giving a 90-hour power reserve.
