The Garmin fenix 8 51mm Solar Sapphire is a multisport GPS smartwatch for athletes and outdoor adventurers. It has a 1.4-inch solar-charged display with a scratch-resistant sapphire lens, a titanium bezel and a built-in LED flashlight. The metal buttons are leakproof, and the watch has a 40-meter dive rating with support for scuba and apnea dive activities.
For navigation, it uses multi-band GPS with SatIQ technology, plus a 3-axis compass, a gyroscope and a barometric altimeter. TopoActive maps with relief shading download over Wi-Fi, and maps for thousands of golf courses and ski resorts are built in. Dynamic round-trip routing lets you set a target distance and get turn-by-turn directions that adjust to bring you back to your start on schedule.
The watch offers targeted strength training plans, real-time stamina tracking, sport-specific workouts and a full range of built-in sports apps. A training readiness score uses sleep quality, recovery, training load and HRV status. Around-the-clock monitoring covers wrist-based heart rate, sleep, respiration, stress and Pulse Ox. It is not a medical device, and the data is a close estimation of the metrics tracked.
