Taking a screenshot on an Apple Watch-like taking a screenshot on an iPhone, iPad, or Mac-is reassuringly simple. Press the Digital Crown and the side button at the same time. You’ll hear a shutter sound effect, the screen will blink white, and a static image of whatever was on the screen at the time is saved.
But where does the image get saved? It does not appear in the Photos app in the Apple Watch. Instead, it’s sent to the associated iPhone.
Grab your iPhone and open the Photos app. Your screenshot will be the newest image under the Photos tab.
