A very rare 18k WG van der Klaauw Astrolabium

This is the pinnacle of Christiaan's watchmaking to date. His most complicated wristwatch features a complication only found to my knowledge on this watch and the rather more famous Ulysse Nardin watch known by the same name. The complexity of the 2D representations of what is essentially a 3D Astrolabe is quite something and much admired by afficianados of astronomical complications in wristwatches.

This 18k WG watch shows a variety of information, the true solar noon, the sunrise and sunset, the moonphase and whether or not there is a solar or lunar eclips happening somewhere on earth. Not to mention the current time and the approximate date!

It comes with all original boxes and papers and is in mint condition. Dial set up for the latitude of Los Angeles.

WILL SELL FOR $32,000
