Garmin Fenix 8 Pro

The Garmin Fenix 8 Pro features a 1.4″ OLED/AMOLED touchscreen with a resolution of 454 × 454 px and a pixel density of 458 ppi, housed in a 51 × 51 mm case that is 16.5 mm thick and weighs 90 g. The display is protected by both branded damage-resistant glass and a sapphire glass layer, and supports an always-on mode for continuous visibility. With a 10 ATM rating and a waterproof depth of 40 m, the watch is built to handle water exposure reliably, while its 26 mm replaceable band offers flexibility for customization.

The watch includes a broad set of onboard sensors, covering GPS, a heart rate monitor, a pulse oximeter for blood oxygenation tracking, a barometer, an accelerometer, a gyroscope, a compass, a body temperature sensor, and a wind speed sensor. It does not include a cadence sensor or a perspiration monitor.

Activity tracking on this watch covers a wide range of disciplines, with support for route tracking, distance, pace, elevation, and step counting alongside multi-sport mode and automatic activity detection. It includes trackback mode for retracing a route, exercise tagging, and a swim stroke counter, and it is specifically designed for both diving and golf. On the wellness side, it tracks sleep with detailed reports, monitors calorie intake, and handles food tracking, giving users a fairly complete picture of their daily activity and recovery.

The watch offers a well-rounded connectivity setup, including a cellular module, Wi-Fi, NFC, and ANT+ support, covering both wireless payments and compatibility with a range of external accessories. It is compatible with both iOS and Android, allowing it to pair with a broad selection of smartphones.

The watch runs on a built-in rechargeable battery that is neither removable nor wireless-charging capable, and it does not include a solar charging option. Battery life reaches 27 days in standard smartwatch mode, drops to 78 hours with GPS active, and 53 hours in training mode, while power-save mode extends runtime considerably to 816 hours.

Health and performance features include HRV tracking, VO2 max measurement, resting heart rate monitoring, fast/slow heart rate notifications, irregular heart rate warnings, fall detection, and a readiness and recovery indicator. Navigation is supported through uploadable maps, fast GPS lock, and Galileo satellite system compatibility. On the practical side, the watch handles wrist notifications, call control, the ability to answer calls via a single onboard microphone, voice commands, vibrating alerts, a silent alarm, a stopwatch, a phone finder, sunrise/sunset times, and thunderstorm risk alerts — though it lacks a smart alarm and a camera remote shutter function. It comes with 32 GB of internal storage and a 1-year warranty.

The companion app is free and ad-free, though an account is required to use it. It covers a broad range of tracking and wellness features, including activity reports, calorie burn, exercise diary, goal setting, inactivity alerts, weight and BMI tracking, water intake, and temperature tracking. Coaching, live tracking, voice feedback, and music playback are all supported, alongside calendar sync, route support, maps, and widgets. The app is personalisable and includes video tutorials for guidance. Women's health tools are present, with period notifications, fertile window notifications, ovulation prediction, and cycle start date prediction. A barcode scanner is not included, and the app does not support account-free use.

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