The apple watch sport is not working properly. The display is being “crazy” once or twice a week and I need to force restart it. Do you know what happen with the watch? Is it a common failure?

Hi

That is not a failure or fault.

Zoom (an accessibility feature) has been enabled on your watch and you have accidentally zoomed in by tapping the display in a particular way.

To disable Zoom:

• On your iPhone, in the Watch app, go to: My Watch (tab) > General > Accessibility > Zoom - turn off.
• Or on your watch, go to: Home screen (via a single press of the Digital Crown) > Settings (cog icon) > General > Accessibility > Zoom - tap and turn off / on.

If the Accessibility Shortcut has been enabled and configured for Zoom, you can also enable and disable the feature more conveniently:

• On your watch: quickly press the Digital Crown (the round button) three times.

To configure the Accessibility Shortcut:

• On your iPhone, in the Watch app, go to: My Watch > General > Accessibility > Accessibility Shortcut (at the bottom) > select / deselect Zoom.

You're welcome!
