Louis-François Cartier founded Cartier in Paris in 1847 when he took over the workshop of his master. In 1904, the Brazilian pioneer aviator, Alberto Santos-Dumont complained to his friend Louis Cartier of the unreliability and impracticality of using pocket watches while flying. Cartier designed a flat wristwatch with a distinctive square bezel. This watch was liked by not only Santos-Dumont but also many other customers. Thus the “Santos” was born. This was Cartier’s first men’s wristwatch. In the early 1920s, Cartier formed a joint company with Edward Jaeger (of Jaeger-LeCoultre) to produce movements solely for Cartier. Cartier watches can be found with movements from Vacheron Constantin, Audemars-Piguet, Movado and LeCoultre. The product range of Cartier includes watches, leather goods and accessories. Cartier operates more than 200 stores in 125 countries.
