The time is the hero, dead centre. Four arcs sit in the four quarters of the rim and each arc's number sits in the corner beside it, so a glance tells you where Body Battery, stress, sleep and recovery stand without reading a single digit. Three more readings run down the centre axis, and the watch battery sits at six o'clock. Seven of the readings are yours to pick in the on-device editor. The four arcs take any metric with a range — Body Battery, stress, sleep score, recovery time, Pulse Ox — and picking one changes the arc, the number, the label and the colour together. The other three take heart rate, steps, calories, floors, intensity minutes, respiration, VO2 max, weekly distance, race predictors, altitude, temperature, pressure, sunrise, sunset, notifications; the line under the time also takes training status, weather, the forecast and your next calendar event. Every reading keeps its own colour wherever you put it: Body Battery blue, stress orange, heart rate red, sleep violet, training green. Tap a reading to open the app behind it. All settings are made on the watch itself — nothing to set up on the phone.
