This edition pays tribute to this story of excellence and celebrates the special relationship between Arnold & Son and the Seddiqi family.

Noble colours

This anniversary edition can be worn with a choice of three bracelets: three-link steel, garnet calfskin and technical fabric in the same colour.

The skeletonised main plate and gold-finished barrels complement the Eastern Arabic numerals on the garnet-hued flange. The palladium-plated bridges echo the steel of the case, creating an equilibrium between materials and colours.

Seven bridges

Designed with purity of line in mind, the Nebula 40 Steel features a rounded flank and deep lugs that highlight the essential: its signature movement.

Inspired by nebulae and their spiral arms, the architecture of the A&S5201 calibre is based on seven functional and harmoniously arranged skeletonised bridges. Facing the centre, they present a radiating and transparent symmetry that forms the collection’s essence. 

At the heart of the star

Beyond its dazzling appearance, the calibre is attractive for its precise finishes. The bridges, hollowed out and polished along all edges, present alternating satin-finish surfaces and shiny edges. Every single component contributes to creating a structured and steady rhythm. 

Click, to see the large size. ▶ BIG FOTO  

On the case back, two intersecting ogival bridges support the functional organs, while the “Rayons de la Gloire” finish elegantly reflects Arnold & Son’s aesthetic.

Power and endurance

Equipped with two large series-coupled barrels, the Nebula 40 Steel offers a remarkable 90-hour power reserve, rare in skeletonised pieces but typical of Arnold & Son calibres. 

Click, to see the large size. ▶ BIG FOTO  

Their energy drives the entire gear train, which follows the star-shaped arrangement of the bridges. The balance at the end beats at a frequency of 3 Hz, demonstrating this exceptional movement’s vitality.

A celebrated alliance

With this Nebula 40 Steel, Arnold & Son pays tribute to Ahmed Seddiqi’s 75-year existence, a symbol of watchmaking legacy and passion.

This limited edition embodies the encounter between two Houses united by the same ethos: that of excellence, creativity and promotion of fine timepieces.

 More than a watch, it seals an enduring bond between the Swiss Manufacture and its visionary partner in Dubai.

ARNOLD & SON – GLOBETROTTER 42 Steel Strand Blue & Greenwich Green Editions

ARNOLD & SON – GLOBETROTTER Steel 42 ‘Strand Blue’ & ‘Greenwich Green’ World-Time Chronometers Limited Edition 2025

 

Click, to see the large size. ▶ BIG FOTO  

CONQUERING NEW WORLDS 

Arnold & Son is revisiting its Globetrotter collection to present a version that is at once more compact, slimmer and easier to read. With its new 42 mm diameter, the Globetrotter 42 Steel features a steel case and is available in two versions, one named ‘Strand Blue’, the other ‘Greenwich Green’, each available in a limited edition of 88 timepieces.

Click, to see the large size. ▶ BIG FOTO   

“It is worth remembering that the English watchmakers John Arnold and his son John Roger were pioneers in the field of timepieces designed for travel and exploration. In 1771, their creations were tested at sea by Admiral Harland, then used successfully on ships as navigational instruments for calculating longitude. These instruments enabled British soldiers, explorers and scientists of the time to gain the upper hand over all their competitors. One such beneficiary was the explorer James Cook, who took John Arnold’s first chronometers (No. 1 and No. 2) on his second voyage of discovery between 1772 and 1775. Another example occurred in 1792 at the Cape of Good Hope in South Africa, when a John Arnold creation was entrusted by the Dutch to the French Rear-Admiral Antoine Bruny d’Entrecasteaux to help him with his search for the explorer Jean-François de Galaup, Comte de La Pérouse. Many of these instruments were also used on board the East India Company’s trading ships, or on vessels such as that commanded by Sir John Franklin during his third expedition to explore the Northwest Passage, an ice-free sea lane to Canada, in 1847.”

In memory of those heroic times when explorers set out to discover the world clutching maps and chronometers, Arnold & Son presents a new version of its famous Globetrotter, a contemporary timekeeping instrument dedicated to today’s travellers. Revisited in size and functionality, the resulting Globetrotter 42 Steel has been finely reworked to offer dimensions that are more in line with modern wearing practices. Its 42 mm diameter steel case appears all the more balanced with its new thickness of just 15 mm, while the exceptional construction of its dial has been retained.

This ultra-graphic dial has also undergone subtle changes that have made it visually more striking and technically even more effective for international travel. The structure retains its famous, delicately curved arched bridge – crafted from steel and worked by hand –which can be considered the signature feature of the collection. The bridge demarcates the hours of the day and night on the 24-hour bezel ring and, with the ruby set in its centre, holds in place the dome representing the northern hemisphere as seen from the North Pole. On the dome, the metallic continents, which have been sunray-brushed to accentuate their relief, stand out clearly and strikingly against the oceans depicted in blue or green depending on the model. 

Click, to see the large size. ▶ BIG FOTO  

Another notable change made by the watch developers at Arnold & Son to this mobile dome – which rotates once every 24 hours and enables world time to be displayed – is the addition of a ring around its perimeter bearing the names of twelve reference cities. Each of these cities, from both the northern and southern hemispheres, is symbolised by its code placed opposite its location on the map. These indicators are intended to give texture to the planisphere and allow the user to instinctively visualise the time in the location of their choice, as it is read opposite the 24-hour transferred numerals on the fixed ring of the local time dial, which itself is read using the two arrows that peak out from under the world map. 

Click, to see the large size. ▶ BIG FOTO  

The decision was also made to present the dials of both versions of the Globetrotter 42 Steel in classic English colours. This is a signature of the design and naming traditions that run through all Arnold & Son ranges. The ‘Strand Blue’ model is therefore a reference to the London street that runs parallel to the River Thames and on which John Arnold’s shop was located. The colours of the ‘Greenwich Green’ version were chosen to recall the wooded hills that surround the Royal Observatory in Greenwich.

Both versions of the Globetrotter 42 are powered by the in-house self-winding mechanical calibre reference A&S6122, whose power reserve has been increased from 45 to 55 hours. This movement allows the home and remote time displays to be adjusted via the three positions of the crown. 

Click, to see the large size. ▶ BIG FOTO  

Like all movements bearing the Arnold & Son signature, it was entirely developed, produced, decorated, assembled, adjusted and cased up at the Manufacture in La Chaux-de-Fonds. Visible through the transparent sapphire crystal case back, the A&S6122 calibre features an engraved and finely openworked oscillating weight and is decorated with the traditional motifs of fine watchmaking. Its main plate is circular-grained, its bridges display radiating Côtes de Genève stripes, the wheels are satin-finished and the screws are chamfered and polished.

It should be noted that its palladium coating offers a particularly interesting light-grey finish that perfectly complements the cases of the models it powers.

These watches, with their sophisticated graphics and practical features for travellers, are worn on alligator leather straps in ‘ink’ blue or ‘Cornwall’ green depending on the model, and are fastened on the wrist with a classic stainless-steel pin buckle bearing the brand’s emblem.

 NEBULA 40 STEEL BLUE EDITION
A HARMONIOUS RADIATING SKELETON

Click, to see the large size. ▶ BIG FOTO 

Elegant in its symmetry. Refined in its detail. Relevant in its strong horological focus. Nebula 40 Steel is a one-of-a-kind skeleton timepiece in which Arnold & Son combines style and substance, movement and design. 

Click, to see the large size. ▶ BIG FOTO 

The star-shaped arrangement of its seven bridges and even its name, Nebula, create a coherent system: the radiating concept that governs the form of Nebula 40 Steel and determines its structure, topography and depth.

Click, to see the large size. ▶ BIG FOTO  

 Following the launch of Nebula 40 Steel in black and a golden edition celebrating 260 years of John Arnold’s legacy, a blue version is joining the variations on this skeletonised timepiece.

CONVERGENCE

Radiating towards the centre, the bridges are arranged around the edge of the main plate, itself formed of intersecting curves. These bridges meet in the middle to give Nebula 40 Steel its structural integrity and provide additional anchor points for the movement’s components.

Click, to see the large size. ▶ BIG FOTO 

Just as each bridge follows the last in quick succession, the organs inside the A&S5201 calibre are arranged in a peripheral kinematic chain. 

Click, to see the large size. ▶ BIG FOTO 

The two large barrels that provide Nebula 40 Steel with a 90-hour power reserve, as well as the balance and small seconds, are positioned along four lines of symmetry. This equilibrium is one of the signatures of the collection.

TRANSCENDENCE

Nebula 40 Steel also comes to life thanks to a host of details stemming from Arnold & Son’s technical requirements, which produce an understated aesthetic effect. 

Click, to see the large size. ▶ BIG FOTO   

These include the openworked bridges with chamfered edges, and the crown mechanism, which has been inverted and transposed to the case-back side to create symmetry with the first wheel at 9 o’clock. 

Click, to see the large size. ▶ BIG FOTO 

The same is true of the wide click spring, which controls the unwinding of the first barrel; the appliqué hour-markers, which have the same faceted design as the hands; and the proportions of the 40 mm-diameter case, which is balanced by a thickness of 9.10 mm to ensure complete elegance on the wrist.

FASCINATION

Last but not least, Nebula 40 Steel, Blue Edition is a confluence of colours. As its name suggests, the dominant shade is the blue of the movement. 

Click, to see the large size. ▶ BIG FOTO 

All the lower levels of the calibre feature a blue PVD treatment, and this hue influences the finishes: horizontal satin on the dial side of the main plate, and Arnold & Son’s signature ‘Rayons de la Gloire’ motif on the reverse.

Click, to see the large size. ▶ BIG FOTO 

In contrast, the bridges, ratchets, cogs and even the balance have a palladium finish to echo the colour of the steel case. A blue strap in alligator leather or rubber completes the timepiece.

Arnold & Son is also presenting a version with a three-link steel bracelet, whose understated design allows the balanced arrangement of the case and movement to truly shine.

A CELEBRATION OF WATCHMAKING
INGENUITY

 Click, to see the large size. ▶ BIG FOTO

This is the story of a dialogue—a conversation between two demanding worlds inhabited by precision, audacity, and obsession with detail. 

 

 Click, to see the large size. ▶ BIG FOTO 

Chronopassion, a watchmaking agitator since 1988, and Arnold & Son, a custodian of British-inspired technical elegance, have created a unique, rare, and spectacular timepiece: the Double Tourbillon "Landscape," an exercise in style as mechanical as it is mineral.

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.

 Click, to see the large size. ▶ BIG FOTO 

The mineral dial becomes a painting, the beige alligator strap an extension of the chromatic harmony, offering a poetic reading of time. 

 

 Click, to see the large size. ▶ BIG FOTO 

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. 

 

 Click, to see the large size. ▶ BIG FOTO 

At noon, local time is displayed in Roman numerals. At six o'clock, the reference time is displayed in Arabic numerals. 

 

 Click, to see the large size. ▶ BIG FOTO  

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.

 Click, to see the large size. ▶ BIG FOTO 

This dual architecture pays homage to John Arnold, a pioneer of marine chronometry, who facilitated the calculation of longitude with his precision watches. 

 

 Click, to see the large size. ▶ BIG FOTO  

In this spirit, this timepiece perpetuates the idea of time being mastered, used, and shared—but never frozen.

High-flying mechanics

At the heart of this creation beats the A&S8513 calibre, entirely developed and hand-decorated by Arnold & Son. 

 

 Click, to see the large size. ▶ BIG FOTO 

It features two gear trains, two barrels for 90 hours of power reserve, and two tourbillons suspended on three-dimensional solid gold bridges, bevelled, polished and satin-finished to perfection.

 Click, to see the large size. ▶ BIG FOTO 

Every finish - from the radiant Côtes de Genève to the circular graining, from the colimaçonnage of the barrels to the polish of the chatons - is pushed to the limit. 

 

 Click, to see the large size. ▶ BIG FOTO 

The oversized pawl that secures the tension of the barrels is a tribute to expressive mechanics, where the useful becomes ornamental.  

Chronopassion inside

As a nod to Chronopassion's singular universe, this unique piece dares to contrast rigorous watchmaking with mineral inspiration.

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.
