The “Holy Grail” of watches from 1933, which took a total of eight years to complete(comissioned in 1925) could fetch $17 million when goes under the hammer. The watch features 24 unique complications, and is the most complicated watch ever built by the human hand. It is reappearing on the market 15 years after its record sale and will coincide with Patek Philippe’s 175th anniversary celebrations.
