HD3 Complication designer Fabrice Gonet created this revolutionary bi-axial tourbillon as a concept and it was so popular that they decided to make an ultra-limited edition of 11. It is made of titanium and platinum. It is water resistant to 50m and has an 80-hour power reserve. The coolest feature is the bi-axial tourbillon which rotates in 1-minute increments on the 1st axis and 30 seconds on the 2nd axis.

Even at a price of $400,000 all watches were sold out quickly, according to HD3.
