Garmin Enduro 3

The Garmin Enduro 3 is built around a 1.4″ always-on LCD with a resolution of 280 x 280 px and a pixel density of 282 ppi, and the display is protected by sapphire glass rather than branded damage-resistant glass. The watch measures 51 x 51 mm with a thickness of 15.7 mm and weighs 63 g, with a 26 mm replaceable band and a total volume of 40.8357 cm³. It supports touch input and is waterproof to 100 m with a 10 ATM rating, making it suitable for aquatic use. The operating temperature range spans from -20 °C to 45 °C, covering a wide variety of environmental conditions.

The Garmin Enduro 3 includes a broad set of onboard sensors suited to varied training and navigation needs. It features GPS, a heart rate monitor, a pulse oximeter for blood oxygenation tracking, a barometer, an accelerometer, a gyroscope, a compass, and a body temperature sensor. Cadence sensing and perspiration monitoring are not included.

The Garmin Enduro 3 covers a wide range of activity tracking capabilities, including route tracking, distance, pace, elevation, and step counting, along with multi-sport mode and automatic activity detection. It supports trackback mode, exercise tagging, a swim stroke counter, and calorie intake tracking, and is also designed for golf. Sleep tracking comes with detailed sleep reports for a more complete picture of recovery. Diving is not a supported activity.

The Garmin Enduro 3 is compatible with both iOS and Android devices and connects via Wi-Fi, ANT+, and NFC. It does not include a cellular module, so an independent data connection without a paired phone is not supported.

The Garmin Enduro 3 carries a rechargeable, non-removable battery that delivers up to 90 days of standard use, 320 hours with GPS active, and 90 hours in training mode. It includes a solar charging capability that extends runtime further, with power save mode listed as offering unlimited battery life. Wireless charging is not supported, so the watch charges via a wired connection.

The Garmin Enduro 3 offers an extensive feature set centered on health and navigation, including HRV tracking, VO2 max measurement, resting heart rate monitoring, fast and slow heart rate notifications, irregular heart rate warnings, fall detection, and a readiness and recovery indicator. It supports map uploads, fast GPS lock, and Galileo satellite systems, and provides sunrise and sunset times along with thunderstorm risk alerts. On the practical side, the watch includes wrist notifications, call control, vibrating alerts, a silent alarm, a stopwatch, a phone locator, and 32 GB of internal storage. Smart alarm, voice commands, the ability to answer calls directly through the watch, and a camera remote shutter function are not included.

The companion app for the Garmin Enduro 3 is free and ad-free, though an account is required to use it. It covers a broad range of tracking and logging tools, including activity reports, calories burned, exercise diary, weight, BMI, water intake, and temperature tracking, alongside inactivity alerts and goal setting. Live tracking, route support, maps, calendar sync, voice feedback, music playback, widgets, and app personalisation are all included, as are coaching features and video tutorials. On the wellness side, the app provides period notifications, fertile window notifications, ovulation prediction, and cycle start date prediction. Achievements are supported to encourage ongoing engagement, while a barcode scanner for food logging is not available.

The Garmin Enduro 3 includes a battery level indicator and supports auto pause during activities. It is compatible with Windows, Mac OS X, and is available on PC, and it works alongside external heart rate monitors and smart scales. There is no external memory slot and no 3.5 mm audio jack.
