The Diver X Skeleton Azure timepiece lets the very essence of movement rise to the surface. In a mineral blue, as deep as the ocean, it lays bare the mechanical intelligence that drives it. A watch conceived for explorers of form and meaning, where every transparency becomes a promise of escape. Poised between technical mastery and the marine horizon, it asserts a rare vision: that of a luxury crafted for motion.
THE SUSTAINABLE DIVER WATCH
The ultra-technical and powerful Diver X Skeleton Azure revolutionises the aesthetics of diving watches. With its titanium DLC case water-resistant to 200 metres, this extraordinary piece presents a dynamic skeletonised face/dial marked with an X in deep black and azure blue.
