Astronomy, time in its purest form is the source of inspiration for the most famous watch atelier in the Netherlands since 1974. Christiaan van der Klaauw Astronomical Watches is the only atelier in the world that is completely devoted to the design and the production of exclusive, hand-made astronomical watches. Known for their iconic masterpieces like the ‘CVDK Planetarium’ – with the smallest mechanical planetarium in the world – and the ‘CVDK Real Moon Joure’ – with the most accurate 3D moon phase in the world.
Winner of the Grand Prix d’Horlogerie de Genève (GPHG) Calendar & Astronomy Award in 2021 in Switzerland. Officially listed on the ‘Haute Horlogerie’ White Paper list of the respected Fondation Haute Horlogerie (FHH).
The iconic Haute Horlogerie CVDK Planetarium is the ultimate way to carry the universe closely to your heart. Our in-house designed module gives you the smallest mechanical heliocentric planetarium in the world. It displays real time the solar orbits of Mercury, Venus, Earth, Mars, Jupiter and Saturn. It also shows you the minutes, hours, date and month. The result is a magnificent spectacle that continues to fascinate in all its complex mechanical beauty. This is astronomical watchmaking at the highest level, intricately designed and executed. Our Planetarium is one of the most complicated watches in our collection, a fitting tribute to the grand masters of planetarium design such as Nicolaas Copernicus, Johannes Kepler, Christiaan Huygens and Eise Eisinga. This smallest mechanical Planetarium in the world is located at the 6 o’clock position. The Sun is positioned exactly in the middle of the Planetarium. The planet closest to the Sun is Mercury. Mercury is followed by Venus, Earth, Mars, Jupiter and Saturn. The planets orbit around the Sun as follows: Mercury 87.97 days Venus 224.70 days Earth 365.24 days Mars 686.98 days Jupiter 11.86 years Saturn 29.46 years The CVDK Planetarium Eise Eisinga Limited Edition won the most prestigious watch prize in the world: the Grand Prix d’Horlogerie de Geneve (GPHG) Calendar & Astronomy Award in 2021 in Switzerland.
CVDK Real Moon Joure
This iconic Haute Horlogerie masterpiece represents a special interpretation of our rotating 3-dimensional real moon indicating the true moon phase. The moon orbits around the earth every 29,530588853 days. Our hand-made 3D miniature moon indicates the moon phase so accurately that it deviates only one day in 11,000 years. It is the most accurate 3D moon phase in the world ever incorporated in a mechanical watch.
CVDK Real Moon Tides
The CVDK Real Moon series, known for the Real Moon Joure and the Real Moon 1980, is completed with a unique Haute Horlogerie masterpiece, the CVDK Real Moon Tides. Next to a rotating miniature moon it carries a complication showing you the sea level tides in a way that has never been seen in a mechanical watch before. Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth. There are multiple types of sea tides. In most locations you will find the ‘principal lunar semi-diurnal’ sea tide. Its period for one rise and fall of the sea level is about 12 hours, 25 minutes and 14 seconds. Waves move up and down in a special window to make this beautiful phenomenon visible. At the 6 o’clock position our unique rotating 3-dimensional real moon - indicating the true moon phase - is shown. The moon orbits around the earth every 29,530588853 days. Our hand-made 3D miniature moon indicates the moon phase so accurately that it deviates only one day in 11,000 years. It is the most accurate 3D moon phase in the world ever incorporated in a mechanical watch.
The CVDK Orion is a striking example of the way we have been integrating astronomical complications and design. It is equipped with a so-called planisphere, a rotating starry sky that turns around every 23 hours, 56 minutes and 4,0916 seconds, giving you the correct view of the stars and constellations above you as seen from most positions on the northern hemisphere.
