Buying Guide: What to Look For in a Fitness Watch

Display Quality and Readability

A bright, clear display is essential for checking stats during workouts or at a glance. The SAMSUNG Galaxy FIT 3 features a vibrant 1.6-inch AMOLED screen with smooth touch navigation, while the Garmin vívoactive 5 models offer a colorful AMOLED display that remains readable even in direct sunlight. Look for high resolution and always-on options if you prefer not to raise your wrist.

Battery Life That Matches Your Routine

Battery life can make or break a fitness watch. The SAMSUNG Galaxy FIT 3 delivers up to 14 days on a single charge, ideal for those who dislike frequent charging. The Garmin vívoactive 5 offers up to 11 days in smartwatch mode (5 days with always-on display), which is still impressive for a GPS smartwatch. Consider how often you want to recharge and whether you need GPS tracking that drains battery faster.

Health and Fitness Tracking Features

From heart rate monitoring to sleep coaching, modern fitness watches provide a wealth of health data. The Garmin vívoactive 5 includes Body Battery energy monitoring, stress tracking, HRV status, and even nap detection. The SAMSUNG Galaxy FIT 3 offers sleep coaching, SpO2, heart rate, and snore detection. If you are into specific sports, check the available workout modes: the Galaxy FIT 3 has over 100 exercise modes, while Garmin provides more than 30 built-in indoor and GPS sports apps, including wheelchair mode.

Compatibility and Ecosystem

Not all fitness watches work with every phone. The SAMSUNG Galaxy FIT 3 is only compatible with Android devices and does not support Samsung Pay or iPhone. The Garmin vívoactive 5 works with both Android and iOS, making it a more versatile choice. If you use an iPhone, Garmin is the way to go. Also consider whether you want smart features like music storage or contactless payments. For a deeper dive into Garmin’s lineup, see our Garmin golf yardage watch review.

Both watches deliver reliable performance, but your choice depends on your phone and preferred features.
