Perpetual Moon
Showcasing one of the largest moons in the watchmaking sphere, Perpetual Moon stands out for its complication and Arnold & Son’s aesthetic approach.
Driven by the moon
Measuring time has relied on the recurrence of astronomical phenomena to find long, reliable points of reference there that can be used under any conditions. The fruit of the human ingenuity, patience, and dedication of countless observers and astronomers from every culture are the markers of cyclical time that are foundational for Arnold & Son watchmaking.
Astronomical signature
The distinctive feature of the Brand’s moon-phase timepieces is their “astronomical” display precision. This term corresponds to an accumulated one-day deviation in the moon phase display every 122 years. Since setting this complication requires great finesse, the Arnold & Son moons generally have a double display with a secondary indicator on the case back next to the movement. This extremely rare display bears witness to Arnold & Son’s involvement in all types of development and reflects its favoured themes, which are as much chronometric as astronomical.
The largest of all moons
Over and above their precision, Arnold & Son’s moon phases attract all the light, either with a large moon opening up over half the dial, or with a 12-mm three-dimensional rotating moon.

Luna Magna
In a starry sky, a large moon alternates between light and dark as it moves through its phases. Luna Magna is the largest rotating moon ever built into a wristwatch.
