Louis Cartier first fashioned this timepiece when his close friend Alberto Santos-Dumont - a Brazilian aviator - requested a style that would allow him to tell the time while flying. It went down in history as one of the first-ever wristwatches and quickly became an iconic design for the house. It has a large, 18-karat rose gold case that'll look a little oversized on smaller wrists and is studded with signature screws and brilliant-cut diamonds. The high-autonomy quartz movement will ensure precise timekeeping, while the rich burgundy alligator strap adds an elegant touch.
