Why does beats per minute change from white to red in exercise mode

Hi

When using the Workout app with the Workout View set to Multiple Metric, all metrics except one are displayed in white.

Rotating the Digital Crown during the workout changes which metric is highlighted / displayed in a different colour - or in a shade of grey, when using greyscale.

When it is highlighted, Heart Rate is shown in red.

Does that mean I somehow changed the bezel without knowing it? Sometimes the bpm goes blank during a run.

It is certainly possible.

You may wish to consider locking your Apple Watch during your workouts:

• Work out with your Apple Watch - Apple Support

How do I lock it?

By following the instructions in the support article linked in my previous reply.

For the best performance from the heart rate sensor during workouts, ensure that you are wearing your Apple Watch sufficiently snugly (but not too tightly) on the top of your wrist.

Apple suggests that you consider tightening the band before starting a workout and loosening it again afterwards:

• Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support

Other issues that can impact sensor performance include skin perfusion and wrist tattoos.
