A close-up shot of a dark-skinned wrist positioned diagonally across the frame, with a smartwatch centered in full view. The watch features a rectangular titanium case with rounded edges, a white and orange watch face with circular graphic elements, and an orange woven textile strap wrapping tightly around the wrist.
