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.
Depicting a view of the Earth’s Northern Hemisphere as seen from space as if directly above the North Pole the Globetrotter’s representation of our planet is exquisitely detailed. Starting with a rounded piece of brass, the different textures of the oceans and continents are brought out by chemical etching with a mask, followed by polishing the upper surfaces. 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.
Seemingly floating above a silvery-white opaline dial with Roman numerals for the hour hand and a circular brushed chapter ring for the minutes, the world-time display is surrounded by a 24-hour sapphire disk fixed to the same bridge that hold the hemisphere, transparent between 06:00 and 18:00 and with a translucent metallic treatment from 18:00 to 06:00, serving as a day and night indicator. The world-time makes one complete rotation every 24 hours.
