黑色石材上的智能手表

A sleek, premium smartwatch with a polished metal casing and illuminated display sits centered on a matte black stone surface. The watch remains still as soft ambient reflections glide subtly across its edges. Minimalist studio environment with a blurred, dark neutral background and shallow depth of field. Slow orbital camera movement circling the watch at a steady pace, maintaining focus on the face and contours. Clean, high-end commercial product style with soft diffused lighting, subtle highlights, and cinematic contrast. Ultra-detailed, 4K, no text, no distractions, product-focused composition, aspect ratio 16:9.
