Your body. Your battery. Body Battery as a glowing charge bar with a live time-to-reserve estimate and a charge/draw energy flow meter. DESCRIPTION: RESERVE turns your watch into an energy display for your body. THE BAR - Body Battery as a glowing battery cell with a reserve notch. The number every EV driver checks forty times a day - now it's you. TIME TO RESERVE - RESERVE watches how fast your Body Battery is moving and tells you when you'll hit reserve at the current burn rate. Not just a percentage - what it means. CHG / DRAW - a center-zero flow meter showing which way your energy is moving right now. Working hard? The marker slides into DRAW. Resting? Watch it drift back into CHG. Your physiology as a live power meter. THE FRAME - a sun arc across the top (sunrise to sunset, with the sun's position as a dot) mirrored by a temperature arc across the bottom (today's low to high, current temp on the dot). One visual language everywhere. FULLY YOURS - 4 data slots x 20 options: HR, steps, distance, device battery, body battery, calories, floors, stress, respiration, active minutes, sunrise, sunset, altitude, barometer, VO2 max, recovery, notifications, step goal %, week number, or empty - 6 colorways: Volt / Ion / Solar / Plasma / Ember / Ghost - each with a matched gradient on the time - Black or warm-light background - Always-on display: full data or minimal, with outlined digits - 12h / 24h time - Settings on the watch (Customize) AND in the Connect IQ phone app Pure black background = maximum AMOLED battery life. Sunrise/sunset works even without weather data (computed from your last GPS position). Body Battery requires a compatible Garmin device and a little wear time to populate.
