Real Moon Joure Green Meteorite White Gold with its three-dimensional Moon

Astronomical Masterpiece - CKRJ77G4

CVDKReal Moon Joure Green Meteorite White Gold

The CVDK Real Moon Joure Green Meteorite White Gold combines the natural structure of meteorite with one of CVDK’s most precise astronomical complications. A three-dimensional Moon follows the true lunar cycle with a deviation of only one day in 11,000 years, set against a deep green meteorite dial and framed by a 40 mm white gold case.

Meteorite andMoon

The green meteorite dial introduces a naturally formed pattern beneath the astronomical display. Its intersecting structures shift subtly with the light, making the surface of each dial visually individual.

Against the cool tone of white gold, the meteorite remains the defining material. At its centre, the rotating three-dimensional Moon adds movement to the composition, translating the lunar cycle into a mechanical indication that changes continuously over time.

Specifications

The Real Moon Joure combines a clear hours-and-minutes display with its three-dimensional moon phase complication. The miniature Moon rotates according to the lunar cycle, allowing its illuminated surface to indicate the changing phase directly.

The CVDK Real Moon Joure Green Meteorite White Gold is powered by the automatic CKM-01 Manufacture movement. Its 60-hour power reserve supports the time indication and the dedicated astronomical module responsible for the precise rotation of the miniature Moon.

The most accurate 3D moon phase

The lunar cycle lasts approximately 29.530588853 days. In the Real Moon Joure, this astronomical period is reproduced through the rotation of a hand-made three-dimensional Moon rather than a conventional flat moon-phase display.

The mechanism is calculated with such precision that its indication deviates by only one day in 11,000 years, making it the most accurate mechanical 3D moon phase in the world. In 2014, the Real Moon Joure was unanimously awarded European Watch of the Year by an international jury in London.

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.
