The model Stardust is a rendering homage to our star SOTHIS (Sirius) in the constellation of the Canis Major (Big Dog). With a lot of know how we engrave the constellation into the dial on a dark blue or black background. The main star was perfect to use it as the permanent second. To make this star to a real hand we place a small drilling in this star as the tip of the hand. For the third dimension we place two rings on the dial as the 30 minute and 12 hour counter. So this is a very special chronograph, not only for astrology lovers.
