Design
Special Case Material: The case is made of a special composite ceramic material, composed of woven ceramic, glass fiber, and carbon fiber layered and pressed within a polymer matrix. Glass fiber is also added for reinforcement, avoiding the brittleness of ordinary ceramic materials. After processing, the surface exhibits a texture with tiny reflective dots, resembling the depth of a starry sky. The case features a black diamond-like carbon coated titanium case back, with an internal sealed titanium container protecting the movement. The overall dimensions are 44.81 mm wide, 53.55 mm long, and 14.30 mm thick. While the design is somewhat bulky, the materials make it relatively lightweight to wear.
**Unique Dial and Color Scheme:** The dial deviates from conventional reflective designs, instead focusing on light absorption. It features finely engraved, three-dimensional circular satin-brushed patterns, while the sub-dials employ a shot-blasted satin-brushed finish. The hour markers are hand-applied with luminescent material, with the azimuth markers exhibiting a yellow-blue glow. It is paired with a bright yellow vulcanized rubber strap secured with Velcro, creating a striking black-and-yellow contrast.
**Core Movement and Functions:**
**Stable Movement:** Powered by the UR-7.30 movement, this movement is protected by a sealed titanium container, much like a mechanical safe, effectively resisting external shocks and ensuring stable operation.
**Center and Functions:** Signature Chronograph Function: Continuing the brand's iconic roaming time display, three cube-shaped hour satellites move in a 120-degree arc over 60 minutes. The satellite indicating the current time completes its rotation under the guidance of a skeletonized retrograde hand. After completing its arc, the hand instantly springs back to zero, ready to guide the next satellite. The minute scale is presented as a vertical track for easy time reading.
Dual Turbine System: Equipped with a dual turbine system, one for shock absorption and the other for controlling the airflow during automatic winding. An adjustment mechanism on the case back allows for adjustment of the balance wheel's operation, such as switching to manual winding mode. Indicators at 11 o'clock and 1 o'clock display the current mode, providing a highly technological user experience.
