Cartier is a French luxury good conglomerate with a rich history dating back to 1847, 1847 when Louis-François Cartier took over his master's jewelry workshop in Paris. Initially focused on jewelry, Cartier expanded into watches, eventually becoming known for its innovative designs and royal patronage. The Cartier “Tank” watch, inspired by the shape of World War I tanks, is credited with the demise of the pocket watch. In the Art Deco period (1020s to 1940s), Cartier defined the fine jewelry of that era. Grandson Louis Cartier designed the “Santos” wristwatch which is still a Cartier staple today, like the “Tank”. Cartier is still a prestigious luxury jewelry brand today, with items like the “LOVE” bangle and the tri-color gold “Trinity” collection among its most popular.
