Arnold Son closes a 260-year chapter with the Constant Force Tourbillon 11 Platinum Edition, a final tribute to the House’s founding brilliance. Its hand-guilloché “tremblé” dial, etched in shimmering, irregular strokes, evokes the windswept ferns of Cornwall, birthplace of John Arnold and cradle of maritime legend. This organic texture paired with a platinum case and white opal subdial turns the watch into a quiet homage to landscape, history and mechanical discipline.
Beneath the surface, the A&S5219 calibre channels the pioneering partnership between John Arnold and Abraham Louis Breguet. A patented constant force mechanism sits proudly on the dial, rearming itself each second to deliver unwavering energy to the tourbillon, echoing the marine chronometers that once conquered longitude. Its one second jumps form a true beat display, indicated by the tip of a blued anchor integral to the mechanism itself.
The tourbillon, visible front and back, revives the elegant geometry of Breguet’s earliest design: a linear, mirror polished bridge, a variable inertia balance and a cage inspired by Arnold’s famed No. 11. Limited to just 11 pieces, this platinum edition becomes both an heirloom and a coda, engraved with a final salute to two friends whose shared curiosity reshaped precision timekeeping.
