Dutch master watchmaker Christiaan van der Klaauw specializes in Astronomical watches and this is possibly his most famous one.
It is considered to be his most ingenious and fascinating timepiece and features the smallest planetarium in the world.
The miniature Planetarium displays the orbits of Mercury, Venus, Earth, Mars, Jupiter and Saturn around the Sun and there is also an annual calendar with the month and the date.
As you can well imagine creating the technical feat of representing the orbiting planets on a watch face require high levels of mechanical complexity and the “Planetarium” uses a heavily modified ETA 2824 .
The casebacks feature a sapphire crystal for viewing the movement and some beautiful engraving by Jochen Benzinger.
