Arnold & Son expands its much-heralded Perpetual Moon collection with a new edition that features a brilliant blue mother-of-pearl dial shimmering within a new, diamond-set 38mm red gold case. And while this addition to the collection features the Swiss watchmaker’s smallest caliber, it powers one of the larger moon-phase displays available.

The new Arnold & Son Perpetual Moon 38 Gold Moonlight features a richly decorated evening sky dial framed with a diamond-set bezel that echoes more diamonds used as hour-markers and on the crown and lugs.

All told, you’ll find 138 diamonds (2.61 carats) glittering on the watch, reflecting light that complements the SuperLuminova-set moon, made more realistic with hand-painted shadows. The Ursa Major and Cassiopeia constellations complete the scene nearby.

The Arnold & Son manual-wind caliber A&S1612 inside the collection is the watchmaker’s smallest, measuring 29.4 mm in diameter so that it perfectly fits the watch’s new 38mm by 10.44mm case.

The beautifully finished manually wound movement, smaller than the A&S1512 found inside the 42mm Perpetual Moon series, still packs an impressive technical punch with a power reserve of ninety hours. And like those larger movements, the new model also boasts accuracy for 122 years – if the watch is kept wound.

Price: $50,300.
