CVDKGrand Planetarium Eccentric

The CVDK Grand Planetarium Eccentric brings the complete solar system to the wrist. It is the only mechanical planetarium watch in the world to display all eight planets, from Mercury to Neptune, orbiting the Sun in real time. Its Manufacture movement is housed in a 44 mm case of 18 ct rose gold, beneath an aventurine glass dial with hand-painted planets.

Created bythree generations of CVDK

The Grand Planetarium Eccentric brings together three generations of Christiaan van der Klaauw. Its origins reach back to Christiaan van der Klaauw’s Kepler’s Planetarium clock from 1995. From prototype to final production, the watch was developed and made in the CVDK atelier.

Caseback

At the heart of the watch is a CVDK Manufacture movement with uni-directional automatic winding. It combines a free-sprung hairspring and variable-inertia balance with a Swiss lever escapement, running at 21,600 vibrations per hour and offering a power reserve of up to 60 hours.

The Eccentric Planetarium

The Grand Planetarium Eccentric is the only mechanical planetarium watch in the world to display all eight planets. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune orbit the Sun in real time, following eccentric paths designed to reflect their astronomical motion as closely as possible.

The difference in scale is considerable: Mercury completes its orbit in 87.97 days, while Neptune requires 164.80 years. Bringing these eight orbital periods together mechanically results in a construction containing a total of 3,338 gear teeth.

Made in theCVDK atelier

Every Christiaan van der Klaauw watch is made by hand and subjected to extensive quality testing in the atelier. Each watch is delivered in a CVDK presentation box and covered by a three-year warranty on the movement and case. Watches from the Collection of Astronomical Masterpieces are also supplied with a removable Swiss Kubik watch winder to keep the astronomical complication running accurately.
