Christiaan van der Klaauw Planetarium "Dunes of Mars"

The Christiaan van der Klaauw Planetarium “Dunes of Mars” ref. CKPM7705 is a remarkable fusion of haute horlogerie and astronomical artistry—an exceptionally rare piece from the only atelier in the world dedicated exclusively to astronomical watches.


Crafted in a limited edition, this reference stands out with its striking aventurine dial, evoking the deep cosmos, contrasted by warm, Mars-inspired tones that give the “Dunes of Mars” its name. At the heart of the watch lies Christiaan van der Klaauw’s legendary in-house planetarium complication—the smallest mechanical planetarium in the world—accurately displaying the real-time orbits of Mercury, Venus, Earth, Mars, Jupiter, and Saturn around the sun.


The beautifully finished automatic movement is visible through the sapphire caseback, showcasing meticulous hand-finishing and the brand’s dedication to traditional craftsmanship. The case is elegantly proportioned, offering a refined yet substantial presence on the wrist, perfectly complementing the watch’s cosmic display.


Both a technical marvel and a piece of wearable art, the Planetarium “Dunes of Mars” is highly sought after by collectors who appreciate independent watchmaking at its most poetic and complex.


A truly rare opportunity to own one of the most distinctive astronomical timepieces ever created.
