Cartier Ballon Bleu 42mm (Reference WSBB0003) is a men's automatic watch, though its classic design makes it suitable for unisex wear. The 42mm case is fashioned from robust steel, complemented by a black dial featuring elegant Roman numerals and protected by a sapphire crystal. Powering this timepiece is the Cartier 1847 MC automatic movement. With a water resistance of 3 ATM and a steel bezel, it's a versatile choice for daily wear.
