Thank you for sharing your thoughts on the Apple Watch SE. It’s great to hear it’s helping your husband monitor his heart rate, especially after his Fitbit stopped working.

Here’s a step-by-step guide to help you customize your watch face:

To add a new watch face, scroll all the way to the right and tap the “+” icon.

Scroll through the gallery of watch faces using the Digital Crown or by swiping.

Tap the watch face you want to add.

After selecting a watch face, you can customize it by tapping “Edit” — here you can change colors, complications (small widgets), and styles by swiping and using the Digital Crown.

When you’re done customizing, press the Digital Crown to save your changes.

Tap the watch face to set it as your current face.
