Longines has unveiled its newest Ladies Diamond Conquest models that combine diamonds with the strength of ceramic in black and white. The beauty of the line lies in the balance between performance and elegance. Each watch is crafted in steel and accented with ceramic on the bezel and bracelet, and each is set with 54 Top Wesselton VVS diamonds around the inside of the bezel and on the dial. The Ladies Diamond Conquest models have a screw-down case back and are water-resistant to 5 bar.
