I’ll go ahead and be the first to say it but we absolutely love the moon phase here at WristReview and we love it in all its forms. From the super simple yet deadly accurate moon phase in the H.Moser & Cie Endeavour Moon to the beautifully complex A.Lange & Söhne Richard Lange Perpetual Calendar Terraluna to the downright bonkers Bovet Recital 18 Shooting Star. So you can imagine we were especially delighted when we found out about the Arnold & Son HM Double Hemisphere Perpetual Moon Watch, this is due to the fact that almost the entire dial is a moon phase, and what a pretty one it is, too!
Other companies wouldn’t dare be this inventive with a moon phase watch. They’d simply prefer to bung the moon phase in some place that’s not immediately obvious but clearly still counts and would be missed if it weren’t there, just like a bass player in some ways. However in the ArnieSon & The Perpetuals band you can be assured that bass has taken full pride of place on this timepiece. The 29mm moon phase has two 11.2mm photorealistic rose gold moons on it, that means they’re going to look as accurate and gorgeous as possible. The gold contrasts excellently with the deep blue lacquered guilloché wave dial. The moon phase is supremely accurate as well, over the course of 122 years it will only have deviated by one day and you can easily adjust it back to the correct indication. To help appeal to those in both hemispheres the HM Double Hemisphere, as the name suggests, indicates the phase of the moon in both the north and south, easily done due to the fact that the phases of the moon are opposite, there’s also a handy reminder of the countries of the world and the equator.
The 42mm rose gold case has slightly curved and straight lugs, no crown guards and a large diameter crown that appears to me like that of a squashed onion crown. The sword hands on the dial have a double finish, meaning that they have a polished look on one side and a brushed finish on the other. Powering the timepiece is an Arnold & Son calibre A&S1512 has two barrels and a power reserve of 90 hours, given that I’ve looked at quite a few watches recently with relatively short power reserves it’s good to see that it hasn’t been overlooked this time. The mechanically wound movement has been put on display on the reverse of the watch and has been decorated with circular graining and Côtes de Genève as well as blued screws. There’s also another indicator that’s been snuck in here and shows the different phases of the moon in a different way. We’ll get to see this watch full at BaselWorld and if you’re thinking of picking one up then he price is $30,500. For more info, please visit arnoldandson.com
