In 1917, Louis Cartier took inspiration from the purity of the lines of the Tank watch to create a new watch shape. The secret lies in the balance between the lines and shapes, the volume and harmony that emanate from the design and lend the Tank its remarkable elegance. In 1904, Louis Cartier granted the aviator Alberto Santos-Dumont’s wish: to be able to tell the time while flying, without having to let go of the controls to check his pocket watch. Rounded edges, symmetrical bevels and curving horns that converge towards the bracelet. First created in the 1980s, the Panthère watch is the ultimate women’s designer watch. Instantly recognisable, the Panthère de Cartier women’s watch takes its name from the bracelet which exudes lusty sensuality and the fluidity of its links which coil seductively around the wrist. Created in 2007 from a new vision of roundness, the Ballon Bleu case is domed on both the front and back. With this watch, Cartier pays homage to the great tradition of watchmaking and brings a new twist to its codes by transforming the “rail-track”, introducing the blue bubble, and adding the optical illusion of the domed sapphire crystal.
