Historical significance

Arnold & Son Perpetual Moon 44 mm Silvered Stainless sits within Arnold & Son's Perpetual Moon line, introduced in 1988. It carries the house codes established since 1764 — stainless steel case, silvered opaline dial and in-house tourbillon, manual-winding — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

Brand history

Arnold & Son has spent more than 262 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Perpetual Moon, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

John Arnold established Arnold & Son in 1764, working from United Kingdom at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Arnold & Son calibre produced today.
