Real Moon Joure Guilloché White with its three-dimensional Moon

Astronomical Masterpiece - CKRJ3324

CVDKReal Moon Joure Guilloché White

The CVDK Real Moon Joure places a rotating three-dimensional Moon at the centre of its astronomical display. Its mechanical moon phase follows the lunar cycle with such precision that it deviates by only one day in 11,000 years. This interpretation combines the complication with a white guilloché dial, a 40 mm stainless steel case and blue ostrich foot leather.

The Moon,in three dimensions

Rather than representing the lunar cycle with a conventional disc, the Real Moon Joure uses a miniature three-dimensional Moon that rotates to reveal its changing illuminated surface.

Its movement follows the Moon’s 29.530588853-day cycle around Earth with exceptional precision. The mechanism accumulates an error of just one day in 11,000 years, making it the most accurate mechanical 3D moon phase ever incorporated into a watch.

Specifications

The Real Moon Joure combines hours and minutes with CVDK’s three-dimensional moon phase. The rotating miniature Moon displays the true lunar phase through its changing position relative to the light.

Caseback

The CVDK Real Moon Joure is powered by the automatic CKM-01 Manufacture movement. It provides a power reserve of up to 60 hours and forms the mechanical foundation for both the time indication and the dedicated Real Moon Joure module.

The most accurate 3D moon phase

The Moon completes its cycle around Earth in approximately 29.530588853 days. Translating that astronomical period into a mechanical watch requires a gear train capable of reproducing the lunar cycle with extraordinary precision.

The Real Moon Joure uses a rotating, hand-made three-dimensional Moon to show the changing lunar phase. Its mechanism deviates by only one day in 11,000 years, making it the most accurate mechanical 3D moon phase in the world. The complication was recognised with the European Watch of the Year award in 2014.

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.
