With its Globetrotter Night, Arnold & Son create a timepiece that plays on nocturnal nuances and city lights under its crystal dome. At once graphic, cartographic and hemispherical, the timepiecegives its display of world times over to the night.
Back in the 1780s, John Arnold contributed to the great revolution in ocean navigation with his marine chronometers. The Globetrotter Night reflects this historical legacy with its cartographic features and world times. As night follows day, Arnold & Son cloaks its Globetrotter in darkness, spectacularly showcasing the northern hemisphere when shrouded in vesperal shadow.
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.
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.
The Earth by night
The Globetrotter Night 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 decorative touches and finishesextend beyond the Earth itself. The chapter ring is circular satin-brushed and the hands are polished and accentuated by red lacquered tips.
These finishes are echoed extensively on the A&S6022 self-winding calibre powering the Globetrotter Night. 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.
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.
Finally, in the interests of fairness, Arnold & Son can also provide a “southern hemisphere” version of its Globetrotter Night on request at the same price.
