Société Cartier is a French luxury goods conglomerate company which designs, manufactures, distributes, and sells jewelry and watches. Founded in Paris, France, in 1847 by Louis-François Cartier. The company maintains its headquarters in Paris, although it is a wholly owned subsidiary of the Compagnie Financière Richemont SA.

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.
