Its red gold case and blue dial make it stand out, but what really makes it unique is the blue-coated movement. Sotheby's is auctioning this special watch on November 15th, 2016 at their Sale of Important Watches. The money from the sale will go towards supporting the Antoine de Saint-Exupéry Youth Foundation. The final price it sold for was CHF 48,750.
