Illusion is a complete digital watch face. In the center, there is the timetable available in both 12h and 24h format. At the top, you will find the heart rate value and the date. In the lower part, there is the battery percentage as range and steps as a numerical value. In the settings, you can choose the color theme between the six available. With a tap on the time, you access the alarms and with a tap, on the steps, you access a customizable shortcut. The Always On Display mode reflects the standard one.

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 value) the heart icon blinks until the reading is completed.
