Freak Diavolo Tourbillon
The Freak is one of the foundational pieces of the Contemporary Horology movement, and possibly the best entrant from a big brand. The Diavolo version adds a tourbillon to the movement which already is carrousel tourbillon, making it the most insane and coolest Freak variant.
This one is in white gold and is like new, complete with box and papers.
