The 38 mm case is crafted from white gold and set with diamonds. The dial of Perpetual Moon 38 Eclipse I is composed of a fine layer of blue aventurine crystal, featuring lace-like cut-outs through which the large ruthenium crystals’ moons can be glimpsed. At 8 o’clock, the main motif scintillates with precious stones. The moon phase’s sky is made of mother-of-pearl in shades from blue to white.
