A watch face featuring ruthenium crystals and a dial made of white opal. A bezel set with baguette-cut diamonds. A three-dimensional moon paved with blue sapphires and diamonds. The first chapter of the Luna Magna Ultimate series illustrates light, astronomical precision and the truly exceptional.

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 have applied their exceptional know-how to creating eight Luna Magna Ultimate I watches. Poetic and rare, they reveal an outstanding level of detail.
