**1. Watch Face: Solar System Layout: The watch face displays a miniature, realistic solar system. Planets orbit the Sun in real-time, with their positions accurately reflecting their actual locations in space. Floating Mechanism: The planets appear to float above the watch face, using advanced 3D technology or holographic projections to create a sense of depth and realism. Sun: The Sun is located at the center of the watch face, emitting a soft, golden glow. It represents the central point of time and space in this design. Orbit Rings: The orbits of the planets are subtly marked with thin lines, indicating their paths around the Sun. These can also function as hour markers. **2. Time Display: Earth Time: The Earth is positioned at the 12 o’clock position, and its rotation indicates the hour and minute, with a subtle glowing trail marking the passing minutes. Space-Time Indicator: A smaller sub-dial or digital display shows space-time, potentially using a logarithmic or exponential scale to represent the vastness of space-time compared to Earth time. **3. Materials: Crystal Dome: A sapphire crystal dome covers the watch face, enhancing the three-dimensional effect and allowing the planets to appear as if they’re floating in space. Luminous Details: The planets and orbit lines could be coated with a luminescent material to glow in the dark, enhancing the celestial theme. **4. Strap and Case: Space-Inspired Design: The strap and case are made from titanium or carbon fiber, with a design that mimics the textures and colors of outer space, possibly with subtle starry patterns. **5. Functionality: Synced Movements: The watch is synchronized with actual astronomical data, ensuring that the positions of the planets and the passage of Earth time are accurate. Digital Interface: A digital interface could be embedded within the watch, allowing users to switch between viewing Earth time and space-time, as well as other astronomical data.
