The Arnold & Son HM Double Hemisphere Perpetual Moon timepiece is a handsome devil of a watch that will make a brilliant addition to your collection. The luxurious case, which is 42 mm in diameter and 11.5 mm in height, is crafted in 18K rose gold and rests upon a brown leather strap with an 18K gold tang buckle.

You’ll feel like royalty with the guilloche-patterned blue translucent dial with gold sword-shaped hands and applied gold hour markers upon your wrist. Additional features include a water resistance to 30 m / 3 atm and a scratch-resistant sapphire crystal.

Stealing the show in every regard is the amazingly large 29 mm moon disc that delivers two gold moon phase indications upon the front and a third upon the back. This precision complication has only one day’s deviation every 122 years, which can be corrected with a single push of the corrector upon the case band.

The exhibition case back allows you to see the gorgeous movement in action: say hello to the hand-wound manufacture A&S1512 caliber, which beats at 21,600 vph, possesses 27 jewels, and delivers a terrific 90-hour power reserve. The lovingly crafted movement includes fine circular graining and Côtes de Genève rayonnantes, manually chamfered bridges with polished edges, and blued screws with polished and chamfered edges.

Standout features: Highly accurate gold moon phase indications; guilloche-patterned blue translucent dial; 18K rose gold case and tang buckle; 90-hour power reserve.
