Arnold & Son x Chronopassion Double Tourbillon ‘Landscape’

Key Highlights

• Unique Double Tourbillon “Landscape” created jointly by Arnold & Son and Chronopassion.
• Two independent time zones to the minute, with mirrored tourbillons and dual opal dials.
• 43.5 mm 18-carat white gold case framing a landscape jasper picture dial.
• Manually wound calibre A&S8513 with twin barrels, 90-hour power reserve and refined finishing.
• Desert beige alligator strap with storm blue lining echoing the mineral dial’s tones.

Mirrored time, shared vision

The Double Tourbillon “Landscape” is a unique collaboration between Chronopassion and Arnold & Son, pairing an unconventional mineral dial with high-complication watchmaking. Two tourbillons face each other across a landscape jasper tableau, held by mirror-polished gold bridges that leave the mechanisms appearing to float and emphasise symmetry and depth.

Chronopassion selected a landscape jasper whose natural strata suggest distant horizons, while Arnold & Son added two white opal dials like twin pages, each devoted to its own time zone. The 43.5 mm 18-carat white gold case acts as a bright frame, and the desert beige alligator strap with storm blue lining extends the dialogue between stone, metal and opal on the wrist.

A timepiece with two voices

Conceived as a traveller’s watch, the Double Tourbillon “Landscape” offers two independent time zones, adjustable to the minute, a feature rarely seen even among high-end dual timepieces. At 12 o’clock, local time is displayed in Roman numerals on the upper opal dial, while at 6 o’clock, the reference time is shown in Arabic numerals on the lower dial, giving each indication a distinct visual language.

Two crowns govern these displays: one at 2 o’clock for winding and setting the primary time, and a second at 7 o’clock for the additional time zone. This clear separation of controls echoes John Arnold’s marine chronometers and keeps daily operation intuitive, so dual time feels like a dialogue between two places rather than a layered complication.

High-flying mechanics

Inside, the hand-wound calibre A&S8513 is developed and finished by Arnold & Son, with two separate gear trains and twin barrels delivering a 90-hour power reserve. The twin tourbillons are held by sculptural solid gold bridges whose polished and satin surfaces turn the regulating organs into the centrepiece of the movement.

The main plate receives NAC treatment and circular graining, while the bridges feature radiating Côtes de Genève with polished, chamfered edges. Wheels are circular-grained and bevelled, jewels sit in gold chatons, and screws have chamfered, mirror-polished heads. The hand-bevelled tourbillon cages and the prominent pawl managing barrel tension stand out through the sapphire case back, underlining the hand-finished character of the calibre.

Chronopassion’s mineral signature

Chronopassion’s identity is most visible in the choice and staging of the dial stone. Landscape jasper is used for its unpredictable patterns, turning the dial into a personal panorama that changes with viewing angle and light, while white opal hour counters float above to secure legibility without overpowering the mineral surface.

The desert beige strap and storm blue lining subtly echo the jasper’s palette, binding case, dial and wrist into a coherent whole. Conceived as a unique piece, the Arnold & Son x Chronopassion Double Tourbillon “Landscape” speaks to collectors drawn to independent watchmaking, intricate mechanics and materials that feel closely tied to the natural world.

Why it matters

The Double Tourbillon “Landscape” shows how contemporary haute horlogerie can combine an independent dual time zone complication with a focused, material-led design. Landscape jasper, opal and white gold are treated as seriously as the A&S8513 calibre, so function and aesthetics reinforce each other.

For discerning enthusiasts in the GCC, this unique collaboration illustrates how independent maisons can create narrative-driven pieces that sit apart from serial production, rewarding collectors who prioritise rarity, craft and a tangible link between movement, mineral and wrist presence.
