This peculiar watch face has 3 indicators for battery, steps percentage, and heart rate. Right behind them is placed a digital time with big font and available in both 12h and 24h format. In the upper part are placed the date info (multi-language), the HR value, and the value of the step.

Notes about Heart Rate detection.

The heart rate measurement is independent of the Wear OS Heart Rate application.
The value displayed on the dial updates itself every ten minutes and does not also update the Wear OS application.
During the measurement (which can also be triggered manually by pressing the HR indicator) a red dot in the center of the HR indicator blinks until the reading is completed.
