A million shades of blue, inlaid with diamonds and white gold stars, converge on the De Bethune blue titanium dial—an extraordinary canvas that captures the infinite complexity of the sky and brings it to life. Merging cutting-edge material research with time-honored craftsmanship, De Bethune’s exclusive natural oxidation process transforms titanium into this luminous, celestial hue, a testament to the Manufacture’s unparalleled expertise. A spherical moon enhances this cosmic masterpiece, deepening the hypnotic impression of depth and infinity. Completing the composition, a sapphire-set case adds an extra touch of brilliance, echoing the endless beauty of the night sky.
