Constant Force Tourbillon

Arnold & Son Constant Force Tourbillon 11 In celebration of the deep friendship and pioneering spirit shared by John Arnold and Abraham-Louis Breguet, Arnold & Son unveils the Constant Force Tourbillon 11—a fitting finale to the brand’s 260th anniversary tributes. Housed in a classic 41.5 mm case of 18-carat yellow gold, this limited edition of 11 pieces marries watchmaking heritage with contemporary mechanical mastery. The white grand feu enamel dial draws inspiration from naval chronometers once sold to British officers, and beneath it lies a constant force mechanism visible through the dial, while the tourbillon regulator reveals itself on the reverse—both nods to the marine chronometers that shaped watchmaking history.
Entirely developed and assembled in La Chaux-de-Fonds, the hand-wound A&S5219 calibre offers a 100-hour power reserve through twin barrels and incorporates a patented constant force device. This mechanism ensures isochronous energy delivery to the tourbillon, preserving precision even as power wanes. Echoing John Arnold’s dedication to accessible chronometry and Breguet’s innovations in regulating systems, this movement distills their shared philosophy into a form both poetic and exacting. The flame-blued anchor that marks the dead-beat seconds is a subtle flourish—both functional and symbolic of the timekeeping science they advanced together.
With enamel artistry, openworked gold bridges, and a recessed white opal subdial bearing Roman numerals, the dial of the Constant Force Tourbillon 11 is a canvas of elegance and clarity. Around the back, the sapphire crystal reveals a tourbillon carriage inspired by Breguet’s first regulator, itself built upon the base of Arnold’s marine chronometer No. 11. The inscription on the engraved silver plate echoes this union: “To the revered memory of John Arnold and Abraham-Louis Breguet. Friends in their time, legendary watchmakers always.” It’s a reminder that horology, at its finest, tells a story that transcends time.

Arnold & Son Double Tourbillon White Gold Amber Edition Arnold & Son has introduced Baltic amber, also known as ‘tiger’ amber, into their collection, marking a first in the watchmaking industry. This unique material, with its rich moiré yellow color, enhances the dial of their iconic double tourbillon watch. The amber, which is fossilized resin from plants that lived 44 million years ago, adds a distinct softness and texture, complementing the white gold case, skeletonized bridges, and white opal hour dials.
The Double Tourbillon White Gold Amber Edition features two tourbillons. It displays local time on the dial at 12 o’clock and another time zone at 6 o’clock. Each dial shows hours and minutes independently, allowing for precise timekeeping across different regions. The watch is powered by the A&S8513 calibre, equipped with two barrels, two crowns, and two time zones.
Featuring a convex sapphire crystal, skeletonized bridges in white gold, and sophisticated finishes such as radiating Côtes de Genève stripes, circular-grained mainplate, double-snailed barrels, sunray-brushed crown wheels, and polished gold chatons. The tourbillon bridges feature bevelling, satin-finishing, and mirror-polishing, demonstrating Arnold & Son’s commitment to excellence.
