The reflection of a shared vision
Two back-to-back tourbillons, suspended in space by mirror-polished gold bridges. Two symmetrical dials in white opal, like two pages turned simultaneously across two time zones. A 43.5 mm white gold case, sculpted to welcome the light. And everywhere, the earthly breath of a “landscape” jasper carefully selected by Chronopassion, whose strata evoke desert reliefs or imaginary panoramas.
The mineral dial becomes a painting, the beige alligator strap an extension of the chromatic harmony, offering a poetic reading of time. The Arnold & Son aesthetic is revealed in a new light, sublimated by Chronopassion’s non-conformist eye.

A timepiece with two voices
The Double Tourbillon “Landscape” is more than a visual exercise. Its heart beats for two independent time zones, adjustable down to the minute—a rarity in the world of travel watches. At noon, local time is displayed in Roman numerals. At six o’clock, the reference time is displayed in Arabic numerals. Each dial is autonomous, and each crown is dedicated: at 2 o’clock for winding and setting, at 7 o’clock for the second time zone.
This dual architecture pays homage to John Arnold, a pioneer of marine chronometry, who facilitated the calculation of longitude with his precision watches. In this spirit, this timepiece perpetuates the idea of time being mastered, used, and shared—but never frozen.

High-flying mechanics
The structure of the A&S8513 calibre is accentuated by extremely skilful hand finishing. This signature feature is taken to new heights of sophistication on Double Tourbillon. From the radiating Côtes de Genève stripes to the circular-grained main plate, the double-snailed barrels, the sunray-brushed crown wheels and the polished gold chatons, everything about the calibre exudes elevation, craftsmanship and excellence.
The elegant wide click spring alone, which prevents the barrels from unwinding uncontrollably, illustrates the level of refinement of this architecture. The bevelling, satin-finishing, and mirror-polishing of the tourbillon bridges in solid gold are the highlights of this showcase of textures. Double Tourbillon offers a worthy mechanical and ornamental counterpart to the aesthetics of its dial.

Chronopassion inside

Landscape” jasper, rare and unpredictable, embodies a taste for the exceptional. It transforms this timepiece into a living sculpture, an intimate territory to be explored.
Double Tourbillon ‘Landscape’ is not just a watch. It’s an encounter between two houses driven by the same love of the unusual.
