Manufacture movementUni-directional automatic winding, power reserve 60 hours, free-sprung hairspring, variable-inertia balance wheel, 36 jewels, frequency 21,600 vibrations/hour (3Hz), jeweled Swiss lever escapement, hand-finished star-shaped bridges, beveled by hand with rhodium plating, skeletonized rose gold-plated brass rotor formed in the shape of the CVDK logo, with rhodium-plated tungsten weight for optimal efficiency.
FunctionsHours, minutes, moonphase, Annual Calendar and Planetarium with Sun, Venus, Earth and Moon. The astronomical display shows the real-time positions and orbits of Venus and Earth around the Sun, as well as the position and orbit of the Moon around Earth.
ComplicationFour separate dial discs, of which three rotate and carry the celestial bodies Venus, Earth and Moon. Venus completes one orbit around the Sun in 224.7 days, while Earth completes its orbit in 365.2 days. The display also incorporates the orbit and phases of the Moon.
Annual CalendarThe outer ring displays the days of the month in a black and white rail track, divided into sections for each month and indicating the individual length of that month. The Annual Calendar requires only one correction every four years, conveniently performed through the crown.
CaseRose gold Au750, ø 38 mm, domed sapphire crystal, sapphire crystal case-back.
DialMatt white dial with astronomical Planetarium displaying the Sun, Venus, Earth and Moon. The rotating discs contain astronomical information concerning their orbital times and speeds.
StrapBlue FKM strap.
BuckleRose gold folding clasp with CVDK logo.
The CVDK Venus Annual Calendar brings together two worlds that have defined Christiaan van der Klaauw Astronomical Watches for more than half a century: the measurement of time and the mechanical representation of the heavens. At the heart of its matt white dial, Venus, Earth and the Moon travel around the Sun, showing their real-time positions and orbits in a sophisticated mechanical Planetarium. Surrounding this celestial display, the Annual Calendar presents the days and individual lengths of each month. Housed in an elegant 38 mm rose gold Au750 case and paired with a blue FKM strap, the Venus Annual Calendar is a technical and refined interpretation of the CVDK astronomical universe.
THE VENUS PLANETARIUM
The Venus Annual Calendar is equipped with the CVDK CKM-01 Manufacture Movement and the specially developed astronomical Venus module. The dial consists of four separate discs, three of which rotate and carry the celestial bodies Venus, Earth and Moon. Together they create a mechanical Planetarium showing the real-time position and orbit of Venus and Earth around the Sun, as well as the position and orbit of the Moon around Earth.
Venus completes its journey around the Sun in 224.7 days, travelling at an orbital speed of 126,071 kilometres per hour. Earth requires 365.2 days to complete its orbit and travels around the Sun at 107,206 kilometres per hour. The Moon revolves around Earth in 27.3 days. These astronomical movements and figures become part of the dial itself, transforming scientific information into a constantly moving mechanical representation of our celestial surroundings.
ANNUAL CALENDAR
Around the Planetarium, the Annual Calendar forms the outermost part of the dial. The days are displayed in a black and white rail track, divided into individual sections for each month. Each section reflects the actual length of that particular month, allowing the calendar and astronomical indications to become part of one integrated composition.
The Venus Annual Calendar requires only one correction every four years. Corrections can be conveniently made through the crown, combining the complexity of the astronomical and calendar mechanism with straightforward everyday use.

CVDK MANUFACTURE MOVEMENT
Visible through the sapphire crystal case-back, the CKM-01 Manufacture Movement offers a 60-hour power reserve and features hand-finished star-shaped bridges with rhodium plating. Its skeletonized rose gold-plated rotor, shaped as the CVDK sun logo, completes the distinctive astronomical character of the movement.

The atelier produces only a limited number of watches every year. In this way, the artists of Christiaan van der Klaauw Astronomical Watches can give every watch the attention it deserves. This attention is reflected in the beauty and quality of the watch. All watches are made by hand and subjected to countless quality tests. Christiaan van der Klaauw are therefore so convinced of the quality of their products, that they give a three-year warranty on the movement and the case.
All Christiaan van der Klaauw watches are delivered in an exclusive luxurious watch box.
For the Collection of the Astronomical Masterpieces the watch box is also fitted with a Swiss Kubik winder. This winder, which can be removed from the box, will ensure that your astronomical complication stays accurate.
