 Where to? Navigate with a worldwide aviation database, moving map and HSI. |  Extend your range with up to 11 days of battery life in smartwatch mode. |  How’s the weather? Know with NEXRAD, METARs, TAFs1 and MOS2. And get customizable alerts for changes. |
 See destination airport information, including frequencies and runway alignment. |  Cross-check your wellness with health data, stress tracking, sleep monitoring and more. |  Get moving with sports apps, animated workouts and performance metrics. |
Strap in for flight.
DIRECT-TO NAVIGATIONNavigate straight to a location or waypoint in the worldwide aeronautical database. Or choose the Nearest function to activate a path to a nearby airport. |
MOVING MAPPan across the moving map with a touch, and tap on waypoints for more information. Plus, see NEXRAD radar1 overlaid on your route. |
WEATHER REPORTSAccess aviation weather, including METARs, TAFs and MOS2, to see winds, visibility, barometric pressure and more1. |
METEOGRAM FEATURESee graphical indications of MOS forecasts for specific airports2, including projections for temperature trends, wind, dewpoint, sky cover, precipitation probability and more. |
HSI COURSE NEEDLEFollow the instrument-like HSI course needle to your destination, so you can easily see if you’re left or right of your desired flight path. |
PULSE OX SENSORCheck Pulse Ox3 to gain awareness of how well your body’s oxygen levels are adjusting to the thinner air at higher altitudes. |
AIRPORT INFORMATIONView runway orientation (including wind components1), lengths and airport frequencies as you approach your destination. |
BAROMETRIC ALTIMETERSee when you’ve reached your desired altitude — or get a vibration alert when you reach an altitude where supplemental oxygen may be required. |
FLIGHT LOGGINGAutomatically start tracking flights on takeoff. Then automatically transfer date, duration, total flight time and route to your flyGarmin.com® account1. |
EMERGENCY MODEActivate to see your best glide speed, estimated glide distance and glide time during an engine-related issue. View a bearing pointer to the nearest airport, and see a list of alternate airports. |
CONFIGURABLE ALERTSSet customizable notifications for new METAR and TAF reports, when destination airport conditions change, when crosswind components exceed a threshold and more. |
ALERTS AND TIMERSManually set vibrating alerts to remind you when it's time to switch fuel tanks or perform other time-critical tasks. |
UTC AND TIME ZONESStay on schedule when you travel with a UTC pointer on the watch face plus multiple time zone displays. |
FLIGHT PLAN TRANSFERTransfer your flight plan from the Garmin Pilot™ app1 to D2 Mach 1, and view the list of waypoints included in your route. |
SUNRISE/SUNSET WIDGETGet daily indications for times of sunrise and sunset — plus hours for civil twilight — by scrolling through available widgets on the touchscreen display. |
Monitor your body.
HEALTH SNAPSHOT™ FEATURELog a 2-minute session to record key stats, including heart rate4, heart rate variability, Pulse Ox, respiration and stress. Then generate a report with those stats to share via the Garmin Connect™ app on your compatible smartphone. |
BODY BATTERY™ ENERGY MONITORINGOptimize your body’s energy reserves, using heart rate variability, stress, sleep and other data to gauge when you’re ready to be active or when you may need to rest. |
WRIST-BASED HEART RATEThe watch constantly samples your heart rate and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming. |
STRESS TRACKINGHeart rate variability is used to calculate your stress level score, so you can see if you’re having a calm, balanced or stressful day. |
SLEEP SCORE AND ADVANCED SLEEP MONITORINGGet a score for your sleep’s quality and insights on how you can do better. Even keep track of the different sleep stages as well as heart rate, stress, Pulse Ox and respiration. |
RESPIRATION TRACKINGSee how you’re breathing throughout the day, during sleep and during breathwork and yoga activities. |
HYDRATION TRACKINGLog your daily fluid intake as a reminder to stay hydrated. You can even have an auto goal for hydration that adjusts based on how much you sweat during activities. |
Push the envelope in fitness.
BUILT-IN SPORTS APPSUse preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing, surfing, indoor climbing and more. |
ANIMATED WORKOUTSThis watch features easy-to-follow, animated cardio, strength, yoga and Pilates workouts you can view on the watch screen. Choose from preloaded animated workouts, or download more from the Garmin Connect online community when paired with your compatible device. |
