Zenith, DEFY series, model: 32.9000.9004 / 78.R582, automatic winding, titanium, case diameter: 44mm. The combination of skeletonization and luxury: The fully skeletonized dial directly showcases the dual-track transmission structure of the 9004 movement. The full diamond inlay on the bezel and case endows the tough sporty style with a luxurious texture. 2. Epoch-making movement design: The dual independent escapement system is the core highlight. The timekeeping and chronograph systems are completely separated, eliminating the traditional clutch structure. Once the chronograph is activated, the central second hand rotates once per second, which is a benchmark design for chronographs in the 21st century. 3. Lightweight wearing: The titanium metal case combines sturdiness and lightness, and is paired with a quick-release strap structure, making it flexible for daily wear and style switching. Original diamond-encrusted single watch
