Arnold & Son Perpetual Moon 38 Eclipse I Limited Edition

Dressed in a sparkling gem-set white-gold case measuring 38 mm diameter, the Perpetual Moon 38 Eclipse I watch ushers in a new chapter for women at Arnold & Son. Its bezel, four horns and crown host a total of 90 brilliant-cut diamonds.

The dial of the Arnold & Son Perpetual Moon 38 Eclipse I watch 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.

For the Perpetual Moon 38 Eclipse I, 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 is endowed with an autonomy of 90 hours.

The moonphase display has an accuracy of 122 years. The various crescents of the ingenious large-moon fill the large aperture located between 10 and 2 o’clock.

The Perpetual Moon 38 Eclipse I watch is fitted with a blue alligator-leather strap with a satin finish and fuchsia lining.
