In true Arnold & Son tradition, the brand has released 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, 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.
