GLOBETROTTER DAY World-Time
Between the 18th and 19th
century, Arnold & Son made a name for itself by creating some of
the most precise marine chronometers of the epoch, which were used not
just to tell the time, but as navigational instruments to determine
longitude and sail safely from one location to another. Arnold & Son
chronometers have taken part in extraordinary voyages, including James
Cook voyages to the Pacific Ocean, as well as Sir John Franklin's
ill-fated third and final expedition to the icy waters north of Canada
in 1845.

chronometers to determine longitude, as have the needs of the modern
traveler.
Arnold & Son has created a timepiece for the modern-day
navigator, always on the move from one time zone to the next: The
Globetrotter.

Part of the
Arnold & Son Instrument Collection, which is inspired by
the high-precision marine chronometers made by
John Arnold and his son
towards the end of the
18th century, the
Globetrotter reimagined the
world-time function in a three-dimensional way.

Held by a large central arched bridge spanning the entire
diameter of the dial, the
Globetrotter's three-dimensional world-time
display takes centre stage. At
45 mm wide and 17.23 mm at its highest
point, the
Globetrotter features one of the world's largest rotating
3D
world-time display on a wristwatch.
Panoramic vision
Beneath a large sapphire crystal dome, an arch supports a half-globe in shades of grey and blue. It depicts the continents, the seas and the lights of the large cities located north of the equator. On the edge of the planet, a sapphire ring breaks down the 24 hours of a day.

Transparent between 6 am and 6 pm, a metal treatment has been used to darken it, indicating the night-time hours. Together, the hemisphere and ring display the time in one part of the world, represented in a highly original way. In the absence of a dedicated hand or city disc, the time is read geographically in accordance with the continents.

Intuitive to read and adjust, the
Globetrotter features a
three-position crown system. The first position is used to manually wind
the movement, the second position sets the local time (hour hand) in
one-hour increments, and the final position is used to set the hour and
minute hands and the world-time. Both the main time display as well as
the world-time function can be adjusted forwards and backwards.
The Earth by night and day
The Globetrotter Day offers a realistic and meticulously rendered interpretation of a three-dimensional map enclosed in a 45 mm steel case. Chemical engraving has been used on the half-globe to outline the continents. The raised parts have undergone a deep-grey galvanic treatment before being hand-lacquered in a black-grey hue, while the oceans are lacquered in grey-blue. Finally, the city lights twinkling in the northern hemisphere are represented by hand-applied silver sparkles.

The mountainous areas are then sandblasted to create a sense of visual depth, then the oceans are lacquered by hand with different blue tones. The entire world-time disk is then treated with a layer of clear lacquer, and finally the entire component is polished. The result is a hemispherical disk full of lifelike details.

Globetrotter Day extend beyond the Earth itself. The chapter ring is circular satin-brushed and the hands, despite being mostly concealed beneath the half-globe, are polished and accentuated by red lacquered tips. The large double-foot bridge supporting the half-globe is a spectacular feature in itself that lends structure to the overall appearance of this timepiece. It is circular satin-brushed and chamfered by hand and held in place by screws with polished heads and chamfered slots.
Watchmaking ergonomics
These finishes are echoed extensively on the
A&S6022 self-winding calibre powering the
Globetrotter Night and
Globetrotter Day. Entirely developed and produced by the
Arnold & Son Manufacture, it has a nocturnal style thanks to the widespread use of NAC-type surface treatments.

The bridges are polished and chamfered, finished with
Côtes de Genève stripes and coloured grey. The skeletonised oscillating weight is engraved and treated chemically with ADLC black and
NAC grey to obtain a two-tone appearance using a matt straight-grained finish. When fully wound, the movement provides a power reserve of
45
hours.

Beyond these aesthetic details, what makes the
A&S6022 calibre special is its easy setting, thanks to a three-position crown. The first winds the movement. The second adjusts the local time hand by one-hour jumps either clockwise or anti-clockwise. The third regulates the hours and minutes in addition to the planet’s rotation. When travelling to a different time zone, the second position enables the wearer to change local time while keeping world time synchronised.

With the
Globetrotter,
Arnold & Son masterfully
demonstrates its unique aesthetic sense and manufacturing prowess,
combining ingenious haute horlogerie with artisanal crafts to produce a
world-time watch that is truly unlike any other.

In the interests of fairness, Arnold & Son can also provide a “southern hemisphere” version of its Globetrotter Night on request at the same price.
