Manufactured in conjunction with Vianney Halter and Goldpfeil, this highly unusual timepiece is finely crafted from a block of solid 18k white gold.

The present watch 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.

It features two apertures for jump hour and geometric moon phases, which automatically adjusted every 6 hours and is calculated to deviate one day every 139 years, making this complication one of the most precise ever created.
