In 1989 – 14 years after founding it – he made the masterpiece that granted him access to the A.H.C.I. (Academy of Independent Creative Horologists) as a member. This table clock, the Planeto Astrolabium, included a three-dimensional planetarium, an astrolabe, and a planisphere for both the Northern and Southern Hemispheres. It remains the most complicated clock ever made in The Netherlands. Seven years later, in 1996, van der Klaauw began constructing wristwatches, making him one of the early independent watchmakers. From the beginning he focused on astronomical watches, building on his clockmaking experience.
