The globetrotting watch is even more precious. Arnold & Son, a Swiss watchmaker with roots in London (in 1764) has coated its Globetrotter in 950 platinum, a noble metal that recalls the era of great explorations, when John Arnold’s chronometers were essential for travellers. In the centre, the Globetrotter Platinum, produced in just 28 pieces, features a dome depicting the northern hemisphere, supported by a large transversal bridge in 18-karat gold. Depending on which side it is viewed from, it is bevelled, polished, and satin-finished. Globetrotter has a ruby in the center which holds the universal time axis.
The watch maintains an essential design, with faceted indexes on two levels, made of 18-karat gold with Super-LumiNova coating. The lower part of the dial, which surrounds the globe, is mother-of-pearl with blue undertones. The world time ring is made of transparent sapphire. Local time is read through the red hands pointing to the hour markers, while for world time reading an imaginary longitude is visually traced from the ruby on the central bridge to the 24-hour ring.
Under a big bridge
The cross bridge of the Globetrotter Platinum is a carved 18-karat gold. It is made with a single piece, with an extraordinary perforation. It features smooth flat sections, satin sides, and wide bevels. The quality and type of finishes are the classic ones of Arnold & Son caliber components. However, an exceptional level of accuracy was used given the large size of the bridge.
Above the equator, the land surface of America, Eurasia and Africa is depicted in minute detail. It is a single element, with a rhodium-plated and polished finish. The reliefs of the mountain ranges are matted. The oceans are hand painted with several layers of lacquer, whose blue pigments enriched with mother-of-pearl powder give them intense depth and luminosity. The ribs, with a lighter shade and with Super-LumiNova, glow at night and further accentuate the relief of this miniature handcrafted work.
Inside, the Globetrotter Platinum has the Maison’s automatic caliber A&S6022. Like all Arnold & Son movements, it was entirely developed, manufactured, decorated, assembled, adjusted and cased within the La Chaux-de-Fonds manufacture. In addition to being openworked, the 22-karat gold oscillating weight is guilloché decorated with a Clous de Paris motif. The A&S6022 caliber is also decorated with the traditional motifs of haute horlogerie: pearlescent plate, Côtes de Genève sunburst bridges, satin-brushed wheels, chamfered and polished screws. The specific finishes consist of a NAC treatment. This type of plating uses precious metals similar to platinum. It gives a high-quality anthracite appearance that matches perfectly, due to its tone and nature, the 950 platinum case of the Globetrotter Platinum.
