This highly unusual timepiece, finely crafted from a block of solid 18k white gold, was manufactured in conjunction with Vianney Halter and Goldpfeil. It is part of a special project on cutting edge timepieces initiated by the German luxury company Goldpfeil and seven members of Académie Horlogère des Créateurs Indépendants. This unconventional creation features two apertures for jump hour and geometric moon phases, which automatically adjusted every 6 hours and is calculate to deviate one day every 139 years, making this complication one of the most precise ever created. Manufactured in a very limited production, this present watch symbolises Vianney Halter’s aesthetic and technical mastery.
