The Arnold & Son HM Perpetual Moon is for sure the nicest moon phase indicator watch in the market. Well, just as if it wasn't stunning enough, the brand released this new iteration during Baselworld 2019. The new HM Perpetual Moon Aventurine is now sporting a beautiful sparkly Aventurine dial. Fitted with the biggest moon phase indication in the market, the Arnold & Son HM Perpetual Moon displays the moon as seen from the northern hemisphere on a wide spread aperture that spans from 10 to 2 o’clock on the dial.

Things to Know About the Watch

The new Arnold & Son HM Perpetual Moon Aventurine is a superb example of Arnold & Son’s technical and artistic excellence. The 42 mm in 18K red gold houses the manufacture Arnold & Son mechanical hand-wound movement calibre A&S1512. The case is finished with mirror polished caseband, lugs and bezel, while the sides of the lugs are satin-brush finished. The winding crown, maintains all the elements of the classical looking Arnold & Son timepieces. 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 o’clock on the dial, reveals the largest moon phase indicator in the market with a diameter of 11.20 mm for the moon alone.

Additionally, this supersized moon is one of the most visually stunning recreations of the moon because it is a three-dimensional sculptured moon that was first hand-engraved and then inserted into the disc. 

The Movement

The new Arnold & Son HM Perpetual Moon Aventurine is powered by the manual wound Arnold & Son calibre A&S1512 with 27 jewels. Fitted with one of the most accurate moon phase mechanisms on the market —with only one day’s deviation every 122 years—, the exquisitely finished movement is fully visible via the display case back. The calibre is also equipped with a double barrel to yield 90 hours of power reserve and on its back side, yet another moon phase indicator is present to make sure the moon phase is perfectly set depending on your location.
