The Roadster watch is inspired by the world of 1950s car racing. The streamlined dial of the case is a trademark of the era, while the sword-shaped luminescent hands, Roman numerals and sapphire crystal are signature Cartier features. Adorned with a white or pink satin-finish dial, the Roadster will equally delight any male or female.
