Cartier's Ballon Blue collection made its debut in 2007. Its unique design stands out with a smooth, round case resembling a pebble. The iconic recessed and shielded crown creates a distinctive "dent" on the dial. The WGBB0016 model boasts a gorgeous pink gold case and a sleek silver dial. Inside, the self-winding caliber 049 keeps things ticking smoothly. And to complete the luxurious look, it comes with a pink gold bracelet.
