Christiaan van der Klaauw is an independent watch brand specializing in watches with astronomical complications. The Christiaan van der Klaauw Orion features a beautiful star chart (Planisphere) at 6 o'clock. The 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. This Dark Matter version of the Orion has a 40-millimeter brushed titanium case. We are an authorised Christiaan van der Klaauw retailer. If you have any further questions, please don't hesitate to contact us! PLEASE NOTE, PRICES ARE EXCLUDED VAT!
