The video features a close-up of a red smartwatch with a black screen. The watch has a circular dial on the side and a digital display. The display shows a spiral graphic and the time "10:09". The watch screen then changes to show the text "Blood O2" and "Results" with a percentage of "95%" displayed. The text "Done" and "You can view Blood Oxygen measurements in the Health app on iPhone" are also visible. The background is blurred, focusing attention on the watch.
