Cartier “Santos Droit” Wristwatch

I feel there are just too much distracting information for all those images on the page...But I guess this is the most interesting part of the whole page, as for an average "nerd" in the HN community:

  "In 1904, the Brazilian pilot Alberto Santos-Dumont complained to his
  friend Louis Cartier that while he was flying with both hands on the
  controls, it was impossible to read the time on his pocket watch. Soon
  afterwards, Cartier sent him a prototype of a wristwatch. It was sold
  from 1911 as the Santos, and was the first watch with the bracelet
  attachment horns integrated into the case. These integrated horns made
  it the first modern wristwatch for men."
