手表光影漂浮 prompt

A luxury silver watch suspended against a deep black background, slowly rotating in place. A crane shot moves smoothly downwards along the watch, revealing the bezel, dial, and crown in sequence. Single key light from upper right creates crisp specular highlights along the polished steel. Macro detail focus on the dial. Subtle particles drift in the surrounding darkness. Cinematic stillness, no morphing, no extra elements.
