The Maison Caran d’Ache and the horological laboratory MB&F undertook an authentic creative odyssey in creating the Astrograph. It all began with the original idea of MB&F founder, Maximilian Büsser: projecting his dreams of conquering space into a writing instrument. It took more than four years for the creative and technical forces at Caran d’Ache to make this dream come true in the shape of a “rocket”. Its structure is based on a mechanism inspired by penknives: a miniature lever – the entry door to the rocket, concealed in the ring of the pen – activates the lowering of three stabiliser legs designed to place the rocket in a vertical position, ready for take-off. Other innovative features enrich this 99-piece limited numbered edition. More than 500 manual operations were required to launch the Astrograph, the most complex writing instrument ever produced by the Caran d’Ache workshops in Geneva.
