Arnold & Son is releasing a new high-jewellery version of its three-dimensional moon model. Above and beyond the technical prowess of inserting a 12 mm lunar sphere into a watch, the piece features superlative gem-setting, both in terms of the stones chosen and the techniques used. From pavé to invisible and channel setting, Arnold & Son is drawing on know-how of the highest level to produce eight Luna Magna Ultimate II timepieces. The 44 mm diameter case is crafted from 18K white gold and is studded with no fewer than 7.62 ct of exceptional-quality diamonds. The extraordinary colour of the Paraíba tourmaline, a rare and much sought-after stone, is the finishing touch on this exotic and refined piece in blue-green tones bordering on turquoise.
