Just as if the Arnold & Son HM Perpetual Moon wasn't stunning enough, in preparation for Baselworld 2016, Arnold & Son brings us a new iteration of what we think is the most beautiful moon phase watch out there. Presented as an evolution of its alluring and precise HM Perpetual Moon, the new HM Double Hemisphere Perpetual Moon, with not one but two of the biggest moon phase indications on the market, rightfully joins the Arnold & Son Royal Collection. For the first time, the HM Double Hemisphere Perpetual Moon displays the moon phases as they can be seen both from the northern and southern hemispheres respectively, all in a single watch.
The new Arnold & Son sophisticated HM Double Hemisphere Perpetual Moon is, indeed, a superb example of Arnold & Son’s technical and artistic excellence. From the inside out, this new timepiece —with rich guilloché dials and two three-dimensional big moons— surprises and delights. The 42 mm case is created in 18-karat red gold and houses the manufacture Arnold & Son mechanical hand-wound movement, the calibre A&S1512.
The 27 jewel calibre offers one of the most accurate moon phases on the market, with only one day’s deviation every 122 years — at which point a single push on the corrector will keep it in sync for another 122 years. The calibre is also equipped with a double barrel to yield 90 hours of power reserve. On the back side, yet another moon phase indicator is present to make sure the moon phases are perfectly set depending on your location.
The exceptional perpetual moon phase indication of this watch is a marvel in many ways. From the aesthetic side, the 29 mm moon phase disc, which runs from 10 to 2 and 4 to 8 o’clock on the dial, reveals not one but two of the largest moons on the market —with a diameter of 11.20 mm for the moons alone. While the first aperture displays the moon phase as seen in the northern hemisphere, a mirror image of the moon phase also shows the state of the moon in the southern hemisphere. Additionally, these large moons are one of the most visually stunning recreations of the moon because they are three-dimensional sculptured moons that were first hand-engraved and then duplicated for the series. The two sculptured moons are then inserted into the disc.
This new watch is one that for sure we can't wait to see in the metal as we report live straight from Baselworld 2016 next month. Our live Baselworld 2016 coverage will begin on March 16, 2016.
