Official description

Arnold & Son is offering its first watch designed, created, embellished, and powered for women. A new case houses a calibre designed for this moon-phase complication. It extends into a blue alligator-leather strap with a satin finish and fuchsia lining.

The 38 mm diameter case is 10.44 mm thick and crafted from white gold. Its bezel, four horns and crown host a total of 90 brilliant-cut diamonds.

The dial of the Perpetual Moon 38 Eclipse I is composed of a fine layer of blue aventurine crystal, featuring lace-like cut-outs through which the large moon disc can be glimpsed. The starry sky is made of mother-of-pearl in a graduation of shades from blue to white. The two lunar discs are depicted by ruthenium crystals. Between them, the constellations have been painted by hand. At 8 o’clock, the main motif of the Perpetual Moon 38 Eclipse I scintillates with precious stones. The cut-outs adorning the lace-like aventurine backdrop have been encrusted with white and blue mother-of-pearl fragments, diamonds, and blue and pink sapphires, all cut to form a large star complete with glistening halo.

Arnold & Son has created an entirely new calibre, which is also the smallest in its collection. At 30 mm, the A&S1612 calibre was designed to fit the new 38 mm diameter case that is just 10.44 mm thick. This manually wound movement with an autonomy of 90 hours thus perpetuates the range of Arnold & Son calibres with impressive power reserves. Drawing on its ingenious large-moon principle, Arnold & Son has naturally incorporated a majestic lunar disc into its Perpetual Moon 38 Eclipse I timepiece.
