Caran d'Ache Caelograph Pens

Caelograph Writing Instrument Details

For the first time, a writing instrument is connected to the reading of the celestial vault, to the laws of astronomy and to the history of time. The limited edition Caelograph, created by Caran d'Ache in its Geneva factory, is the result of technical excellence and taste for invention specific to the House's craftsmen. This ingenious instrument is addressed to the admirers of science and to those who stop for a while to contemplate the stars at a given time and place.

Available in three materials and in three basic latitudes, Caelograph is equipped with manually adjustable astronomical position functions, like historical measuring and navigation instruments. On the body of the fountain pen or the roller pen unfolds the silent spectacle of the constellations. The light of the stars is symbolized by silver particles impregnated in the night blue China lacquer and, for some versions, by crimped diamonds.

Sign of rarity, intended for an informed collector, a unique piece has been made in solid pink gold and set with 22 diamonds. Its piston pump, housed in a gold barrel, is crowned with a diamond. Reflecting a poetic sense and a rare technical precision, Caelograph brings back our ancestral link with the stars and their role in the development of science and the arts.

The Caelograph is produced in three versions and presented in noble box. The Alpha edition is coated in platinum and limited to 120 fountain pens and 120 roller pens, a reference to the 12 constellations of the zodiac and the 12 months of the year. The Sirius edition is gold plated and set with a diamond as a tribute to the brightest star in the heavens. It is limited to 52 pieces for the 52 weeks of the year. For those who love the infinity of space, the Zenith refers to the highest point imaginable or the highest degree of knowledge. Only one Zenith piece has been produced, in solid rose gold decorated with 22 diamonds symbolizing the 22 brightest stars in the sky; the clip and piston pump are also set with a diamond. Each piece has been produced to the demanding Swiss Made quality standards and carries a lifetime guarantee. Presented with a matching compass and inkwell, the Caelograph invites you to touch the stars with Caran d’Ache’s most beautiful pen.
