Arnold & Son HM Double Hemisphere Perpetual Moon

The Arnold & Son HM Perpetual Moon, which has one large cut-out depicting the moon phases as seen from the Northern Hemisphere, is now available in a dual hemisphere model.

Interestingly, because the secondary moon phase dial – located underneath the main dial – already has two moon discs on the single hemisphere model (the 11.2 mm moon discs are mirror images of each other), the new HM Double Hemisphere Perpetual Moon is able to utilize the same exact movement (caliber A&S1512). In fact, the only difference between the dual and single hemisphere models is the additional cut-out on the lower half of the dial, and a new marking in the center that shows indiciates the northern and southern hemispheres.
