ARNOLD AND SON PERPETUAL MOON 38MM WATCH

The Perpetual Moon 38 Red Gold by Arnold & Son is a luxury watch in a 38 mm red gold case, with a blue aventurine dial that recreates a starry sky. Its 30 mm A&S1612 caliber, specially designed for this model, is manually wound and offers 90 hours of power reserve. The moon phase complication is so precise that it will take 122 years to deviate a single day with respect to the real moon.
