Though Louis Cartier, who lived from 1875 to 1942, popularized the wristwatch over the traditional pocket watch, he did not actually make the first wristwatch. Patek Phillipe created the first wristwatch in 1868, before Cartier was even born. But Cartier was passionate about the workings of mechanical watches and wanted very much to have his own line of elegant watches.In 1904, Cartier's friend Alberto Santos-Dumont requested a watch that could be easily used during flights, and Cartier developed the Santos wristwatch - the first wristwatch made for men.
