Garmin Fenix 8 AMOLED Sapphire

The Garmin Fenix 8 AMOLED Sapphire features a 1.4″ AMOLED always-on display with a resolution of 454 x 454 px and a pixel density of 458 ppi, protected by sapphire glass rather than branded damage-resistant glass. The case measures 51 x 51 mm with a thickness of 14.7 mm and weighs 92 g, with a 26 mm replaceable band and a total volume of 38.23 cm³. The touchscreen is fully waterproof, rated at 10 ATM with a waterproof depth of 40 m, and the watch operates reliably across a temperature range of -20 °C to 45 °C.

The watch includes a broad set of built-in 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.

The Garmin Fenix 8 AMOLED Sapphire covers a wide range of activity tracking capabilities, including route tracking, distance, pace, elevation, and step counting, along with trackback mode and automatic activity detection. It supports multi-sport mode and is specifically designed for both diving and golf, while also offering a swim stroke counter for pool and open-water sessions. Sleep tracking comes with detailed sleep reports, and exercise tagging gives users a straightforward way to log and organize workouts. Additional tracking extends to calorie intake, rounding out a fairly comprehensive picture of daily health and activity data.

The watch is compatible with both iOS and Android devices and connects wirelessly via Wi-Fi, NFC, and ANT+, covering a range of pairing and data transfer needs. It does not include a cellular module, so an independent mobile connection is not available directly from the watch.

The watch runs on a rechargeable battery that is neither removable nor wirelessly charged, and it does not include a solar charging option. In smartwatch mode, battery life reaches up to 29 days, while GPS use extends to 84 hours and training mode delivers up to 62 hours before requiring a charge.

On the health monitoring side, the watch tracks HRV, resting heart rate, and VO2 max, and provides readiness and recovery scores alongside fast/slow heart rate notifications and irregular heart rate warnings. It also includes fall detection and thunderstorm risk alerts for added safety outdoors. Navigation is supported through fast GPS lock, Galileo compatibility, and the ability to upload custom maps, while sunrise and sunset times are available directly on the wrist. For everyday use, the watch handles wrist notifications, call control, the ability to answer calls via a single built-in microphone, voice commands, vibrating alerts, a silent alarm, a stopwatch, and a phone-finding function. It does not offer a smart alarm or a camera remote shutter. Internal storage stands at 32 GB, and the watch comes with a 1-year warranty.

The companion app is free and ad-free, and can be personalised with widgets, though an account is required to use it. It covers a broad range of tracking features including calories burned, weight, BMI, water intake, temperature, and activity reports, and sends inactivity alerts to help users stay on track with their goals. Live tracking, route support, integrated maps, and calendar syncing are all included, alongside coaching, voice feedback, music playback, and video tutorials. Goal setting and an exercise diary provide structure for training, while the achievements system adds a progress-oriented layer to daily activity. On the women's health side, the app handles period notifications, fertile window notifications, ovulation predictions, and start date predictions. A barcode scanner is not available within the app.

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