Caran d’Ache reveals a unique fine writing instrument, the Caelograph that combines technical knowledge with design, exploring one of the most fascinating passions: the sky.
In its long tradition of innovation, Caran d’Ache has developed another exceptional writing instrument, which once again demonstrates their creativity and competence. As the inventor, always looking for new solutions, also the craftsmen of Caran d’Ache has worked closely with an astronomer, to produce this unique tool, which explores the sky and stars.
A fascinating journey into the cosmos
It’s a pen? An instrument for observing the sky? A masterpiece? The Caelograph is all of these things together. With a name that literally means “write the sky,” this ingenious mechanism allows you to see the position of the stars and constellations at any given time. It brings to life the mystical relationship that has ever existed between man and stars, earth and sky, since the dawn of time.
With its mysteries, myths and legends, the nature of the cosmos has always given rise to countless questions. Over the millennia, humans have learned to observe, measure to better understand and use the stars and their motion, as indicators of time and direction. By the first explorers to the most modern research in physics the constellations and the stars guided the progress of man and inspired his dreams. Caelograph brings a part of these dreams within reach.
Technical description:
As a tool for writing and observation, Caelograph symbolizes the union between art and science, man and stars.
Produced in a limited edition of 3 lines, Caelograph is Caran d’Ache’s tribute to astronomy.
Caelograph reproduces the chart, finely engraved on midnight blue Chinese lacquer with delicate silver details that give it a shiny appearance. The upper part of the cap and the writing unit reporting the hour lines that are located on the sundial. The end of the pen is decorated with a compass rose, while the clip is in the form of the compass needle to evoke the eternal bond between navigation and astronomy.
With great technical expertise, this unique invention is a map of the sky enhanced by the dark blue Chinese lacquer. In addition to the normal required accuracy, laying a flat map on the curved surface of the pen is even more of a challenge. For the first time, the projection process known as Mercator was applied to a writing instrument.
As a second technical step, Caran d’Ache was set to lay on a small area such as a pen, no less than 51 constellations and 353 stars visible from the North.
And that’s not all! The chart is mobile and allows you to specify the position of the stars at a given time. This amazing capability is made possible by a unique mechanism with high precision based on two rings. One of the two rings is movable and dedicated to time, while the other, fixed, indicates the month and day. Adjusting their location, the map is placed in turn on the time and date requested. A semi-transparent sleeve reveals the visible part of the sky, indicating the horizon, cardinal points and the zenith.
Alpha Edition
The Caelograph features a chart of the sky that is delicately engraved on night blue Chinese lacquer impregnated with silver particles. It represents 51 constellations and 353 stars, observable from the Northern hemisphere, including Sirius. The Alpha version, coated in platinum, is 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.
Connect to the sky and personalize your Caelograph. Caran d’Ache proposes three latitudes (20°N, 30°N and 45°N) and will personalise the writing instrument by engraving it with the coordinates of any location you choose.
Sirius Edition
Gold plated, 1 diamond. The diamond represents Sirius in the constellation of Canis Major, the brightest star in the sky. Limited edition of 52 pieces, reflecting the 52 weeks: the sky returns to its original configuration after a one-year revolution. The diamonds set in the Sirius and Zenith editions are composed of carbon produced in the heart of the stars.
