This is a watch I did for myself with the data I like.

On top there is meteo information:
- Top blue curve is humidity
- 54% is the chance of precipitation
- 25° is actual temperature
- 28° is felt temperature
- 30° and 15° are minimum and maximum temperature of the day
- 80m is the actual elevation

At middle: date and time
- The background blue behind the time moves depending on time.
- Next to the time, body battery and recovery time after exercise (max is 96h and to have a quarter = 1 day)

On bottom: heartrate live data chart and stress live data chart on last 3hours.
- The color of the heart and the lines chart is updated in realtime depending on the heartrate value. The color is matching the Garmin heartRate colors (so it's a lot of greyish/blueish/greenish while doing relax stuff).
- the stress level number and the stressed smiley also change color depending on its value.

Then battery life
Then steps in the shape of a smile to have a happy feeling :)

--------

The values displayed during low power mode are (from top to bottom):
- Temperature
- Date
- Time
- Body battery and recovery (only data, not the circle)
- Current heart rate value in the heart only (good color is updated)
- Stress smiley (good color is updated)
