Arnold & Son unveils Luna Magna Ultimate I

A watch face featuring ruthenium crystals and with a dial made of white opal, the Luna Magna Ultimate 1 has a bezel set with baguette-cut diamonds and a three-dimensional moon paved with blue sapphires and diamonds. In addition to the technical feat of placing a mechanical star measuring 12mm inside a watch, this piece displays superlative jewel-setting ability, both in the stones and techniques used. With paved and invisibly set precious stones, Arnold & Son has created eight Luna Magna Ultimate I watches. The timepiece is powered by the hand-wound A&S1021 calibre, entirely developed and created in-house. This calibre, designed around the lunar globe, has a power reserve of 90 hours and a regulating organ at a frequency of 3 Hz.
