The “No Data” message will display if data was currently unavailable for this field. This could happen for a variety of reasons, and it’s likely only temporary.

For example, if this is a metric reported by a local weather station, and equipment malfunction at the weather station may prevent this information from being available to Garmin and, by extension, your watch face.

Another example would be if your metric is “Respiration Rate” and your watch couldn’t calculate a valid value. That could occur because the watch is not on your wrist, too loose on your wrist, or just because… In any event, once the information becomes available again, the data should come through again.

In general, your watch is indicating that it just doesn’t have this value available to display.

To resolve this message, you can wait a while and see if it resolves itself. Otherwise, select another metric that is available.
