This is the ultimate way to carry the universe closely to your heart. The 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. The 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
