Caran d´ Ache Caelograph Alpha 45 FP Limited Edition 120 Pen 2013 Product type: Fountain pen Brand: Caran d' Ache Model: Caelograph Alpha 45 FP Nib / Refill: M / 18K white gold Accessories: With original box and guarantee booklet This is the first time that a writing instrument has been linked to the celestial vault, the laws of astronomy and the history of time. The Caelograph limited edition, created by Caran d’Ache at its Geneva Manufacture, stems from the technical excellence and the taste for original inventions cultivated by the in-house artisans. This ingenious instrument was designed for admirers of science and for all those who take the time to stop for a moment to gaze at the stars at a given time and place. Available in three materials and three basic latitudes, Caelograph is equipped with astronomic position functions that are manually adjustable, like historical instruments for measurement and navigation. A silent show of the constellations adorns the body of the fountain pen and roller pen. The light of the stars is symbolised by night blue Chinese lacquer scattered with silver particles and in some versions, set with diamonds. A rare one-of-a-kind variation designed for a seasoned collector has been created in solid pink gold set with 22 diamonds. Its piston ink pump, housed in a golden barrel, is crowned with a diamond. Born of a sense of poetry and rare technical precision, Caelograph revives our ancestral ties with the stars and their role in the development of science and art. Edition Alpha 18 K white gold Platinum-coated trim Per latitude 45°N Comes with: Caran d'Ache Caelograph Alpha Edition 45 N Fountain Pen Caran d'Ache Caelograph 30ml Ink Caelograph Alpha Compass
