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 80 brilliant-cut diamonds. This sumptuous setting announces the ornamental richness with which Arnold & Son has graced the dial of this large-moon timepiece.

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.

By playing with transparency, colour and mineral composition, the Perpetual Moon 38 Eclipse I showcases the know-how of Arnold & Son as it adopts new, particularly expressive techniques.

High standards

The Perpetual Moon 38 Eclipse I transposes the high watchmaking standards that have always guided the brand into the world of ladies’ timepieces. As a result, the Swiss Arnold & Son Manufacture 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.
