In 1904, Louis Cartier created the company's first wristwatch at the request of Alberto Santos-Dumont, a trailblazing Brazilian aviator. Louis's close friend Alberto complained that pocket watches were inconvenient for flying because they required both hands to be on the controls. Louis created a straightforward, sophisticated, and useful wristwatch with a small, square bezel and flat face that made it easy to see the time at a glance. The "Santos" watch was the first wristwatch made by Cartier for men.
