Enable Zoom Feature on Your Apple Watch
On your watch, head to Settings > General > Accessibility. Tap “Zoom” from the menu and turn it on by toggling on the “Zoom” switch.
You can Enable Zoom from Your iPhone Too
If your watch isn’t handy or you prefer to use your iPhone, you can. Launch the Apple Watch app and head to General > Accessibility > Zoom. Toggle it on, and here you can adjust the maximum zoom level, as well.
Now that you have Zoom enabled, you can double-tap the display with two fingers to blow up the content on the watch display. You then need to continue using two fingers to move the content on display around. You can also use the digital crown to adjust the view. To return to the regular view, tap the display with two fingers again. Now, it’s worth noting here that these steps may change a bit once Apple releases iOS 13 and watchOS 6. Apple showed off a lot of what’s to come at its WWDC 2019 event earlier this month. In fact, you will be able to control more from the watch without relying on the iPhone. Apple is making it more of a standalone device. But I doubt the Zoom Accessibility feature would be removed. It might even gain more features. Still, for now, if you need help in viewing certain items on your Apple Watch, the Zoom feature is a great way to do it.
