A generative aurora borealis flows across your wrist - a different color pair, wave shape, and rhythm every calendar day, and it speeds up and glows brighter in real time with your heart rate. Features: * A procedurally generated aurora background - the ribbon color pair, wave frequency, and amplitude (and some days, a third faint ribbon) are all picked deterministically from the calendar date, so no two days ever flow quite the same way * The aurora's flow speed and brightness react live to your current heart rate - calm and resting keeps it slow and subtle, an elevated heart rate makes it flow faster and glow more vividly * A quiet twinkling star field behind the ribbons for depth * Soft, modern time display sitting right at the edge of the aurora band * Three fully configurable data fields below the aurora, each individually switchable between an icon or a text label * If Heart Rate is one of your chosen fields, its color pulses live in sync with your current heart rate * Compatible with both round and square-screen watches How the reactivity works: * Every calendar day, the aurora's color pair (from a curated set of authentic aurora combinations - green/violet, teal/pink, cyan/purple, and more), its wave frequency, and its amplitude are picked from a day-hash, the same deterministic technique used in this store's "Color of the Day" and "Mood Bloom" faces - no two days repeat the same way for a long time * Throughout the day, your live heart rate drives both how fast the ribbons flow and how bright/vivid they glow - it's a living, breathing background that visibly responds to you in real time, not just a static animation Supported field metrics (choose any of the 3 fields): * Heart Rate / Heart Rate Average * Steps * Altitude * Stress * Calories * Distance * Floors Climbed / Floors Descended * Meters Climbed / Meters Descended * Body Battery * Sunrise / Sunset * Notifications / Bluetooth Status * Pulse Ox * Respiration Rate * Weather (with temperature) * Battery Level * VO2 Max * Do Not Disturb * Temperature (current, feels like, high/low) * Humidity * Wind Speed / Wind Bearing * Precipitation Chance * Pressure * Overnight Recovery * Cloud Cover * Dew Point * UV Index * Visibility Customizable: * Background, stars, date, hour, minutes, and each of the 3 data fields - all individually colorable from a curated palette of 63 colors * Each data field switchable between icon display or text label * 12h/24h time format toggle * 13 date format options * Always-On Display: choose whether the date and/or hour stay visible while the screen is dimmed, plus an option to use a separate custom color specifically for Always-On mode * Battery: show/hide toggle, dynamic icon colors that automatically shift with battery level (or a fixed text/icon color of your choice), and a display mode toggle between percentage and estimated days remaining * Distance unit: km, mi, yd, or ft * Altitude and elevation unit: m or ft * Temperature unit: Celsius or Fahrenheit This watch face includes a free 30-minute trial, so you can try it on your watch before buying.
