Amazfit makes serious smartwatches at budget prices and the GTR 4 is their best work. Fourteen-day battery life from a watch that looks like an actual watch rather than a fitness tracker, built-in GPS that's accurate enough for running and hiking, and heart rate plus SpO2 monitoring that's calibrated properly. Over 150 sports modes means it handles whatever training you do, and the round face is proportional rather than a shrunken phone screen. Exceptional value that embarrasses watches at twice the price.
Garmin's mid-tier running watch is the most capable health and fitness tracker at this price — the metrics go beyond step counts and heart rate into genuinely useful territory. Training readiness scores tell you whether your body is recovered enough to train hard, body battery estimates your energy levels throughout the day, and the AMOLED display is visible in direct sunlight. The 13-day battery life means charging is a weekly rather than daily consideration. For anyone who trains seriously.
The ultimate sports watch — the Fenix 7X Pro Solar charges itself in sunlight, extending an already extraordinary battery life to near-indefinite endurance in outdoor conditions. A titanium case that's both lighter and harder than steel, sapphire crystal that won't scratch, and sensors for every sport you'll ever attempt including diving, skiing, trail running, and triathlon. Garmin's training metrics are the most sophisticated consumer-grade performance tools available. A watch for people who actually use everything a watch can do.
