An exceptional dial
The base plate of the dial was cast by Precinox in La-Chaux-de-Fonds, and is made from a special white gold alloy in order to facilitate all these techniques. The cloisonné world map is made by Donze Cadrans. The continents are displayed in a blue/grey finish and softly blasted to feature the terrain. Each continent is then contained within thin (0.1 mm) walls of white gold, barriers against the five seas which are finished in turquoise.
