Also the breathing one further down (a head of a person exhaling with the number 12).
The icon of the man breathing out fumes indicates that the watch has sensed that your breath stinks. In your case for the past 12 hours. You should brush your teeth more often.
Actually it means that 12 people have died from bad breath.
You might need to Google your specific model number.
I found a generic chart for Garmin here:

I really appreciate that. I couldn’t find anything either. I’m guessing now that it could be related to the watch face itself (pacing, a 3rd party watch face). I’ll check it out.
Edit: found it. It’s called resilience.

It’s part of the watch face itself. I didn’t realise they could do that. Manual: https://drive.google.com/file/d/1mTvYtq3fDpbrx4MXsmsuamu7wesbEQ7R/view
If I had to guess it would be breaths per minute
You’re right. It’s breathing rate on this watch face. Thank you for putting me on the right track.
