Apple Watch series 5 dead pixels?

Hello kaya166,

Thank you for reaching out to Apple Support Communities! It sounds like you've noticed what appears to be dead pixels on the display of your Apple Watch Series 5. You're in the right place to find a resolution.

It can be normal to experience a limited number of pixel anomalies, as outlined in the following resource:

Since the visual issues seem to be occurring in very specific conditions, it's possible this is more environmental or software in nature, rather than a hardware issue with dead pixels. Here are a few suggestions to help further isolate potential causes:

1. Update the Apple Watch to the latest watchOS: Update your Apple Watch - Apple Support
2. Restart the Apple Watch: How to restart your Apple Watch - Apple Support
3. Switch to a different watch face, then try to replicate the behavior: Change the watch face on your Apple Watch - Apple Support
4. Adjust the brightness level of your Apple Watch: Adjust brightness, text size, sounds, and haptics on Apple Watch - Apple Support

Keep us posted on the results.

Cheers!

I had 3 stuck pixels when I bought my Apple Watch Series 5. I took it back to the Apple Store within the return window and they exchanged it without a hassle.
