The New Arnold & Son x Chronopassion Double Tourbillon “Landscape”

In 2014, Arnold & Son marked 250 years of John Arnold’s horological legacy with the debut of the Double Tourbillon Escapement, a timepiece that introduced a mechanically ambitious concept: two independent time displays, each driven by its gear train and regulated by its tourbillon. This duality, both technical and aesthetic, was made possible through separate setting mechanisms and a commitment to symmetry. In recent years, the model has reappeared as unique editions, like the striking executions with green malachite and blue aventurine glass dials, each a one-off piece and each maintaining the architectural balance that defines the series. This year, the concept returns, created in collaboration with Chronopassion, the famously avant-garde Parisian retailer, as the Arnold & Son x Chronopassion Double Tourbillon “Landscape.”

Sharing its specifications with earlier models, the watch is housed in an 18k white gold case measuring 43.5mm in diameter and offering 30 meters of water resistance. Twin crowns at 2 and 7 o’clock enable the winding of the movement and independent setting of the two time zones. The case is topped with a domed sapphire crystal featuring double-sided anti-reflective coating, while a sapphire crystal caseback reveals the movement within.

For this collaboration, the central dial has been crafted from a piece of landscape jasper, selected by Chronopassion, a mineral known for its striated, earthy textures that evoke desert vistas or abstract topographies. Two symmetrically placed white opal sub-dials display separate time zones: Roman numerals at 12 o’clock for local time and Arabic at 6 o’clock for home time. Each operates independently, set via its own crown, making this one of the few watches to offer true dual-time functionality down to the minute. Flanking the dial at 3 and 9 o’clock are large apertures that reveal the twin tourbillons, each suspended beneath skeletonised three-dimensional bridges in polished and satin-brushed 18k white gold.

Driving the Double Tourbillon “Landscape” is the hand-wound calibre A&S8513, developed with La Joux-Perret. The movement features two barrels, dual independent gear trains and provides a 90-hour power reserve, operating at 21,600 vibrations/hour. The calibre is finished to haute horlogerie standards, with NAC-treated bridges, radiating Côtes de Genève, circular graining, hand-chamfered edges, and white gold chatons anchoring the jewels.

The watch is paired with a desert beige alligator leather strap, lined in blue, and fastened with a white gold folding clasp. The Double Tourbillon “Landscape” is a unique piece available from Chronopassion, Paris, and the price is upon request. For more information, please visit arnoldson.com.
