2026 comparison

|Sources: Amazon, ManufacturerGarmin epix Pro (Gen 2) Sapphire Edition (47mm) vs Samsung Galaxy Watch6 Classic (47mm, Bluetooth)
The Garmin epix Pro (Gen 2) Sapphire Edition (47mm) is the flagship option, while the Samsung Galaxy Watch6 Classic (47mm, Bluetooth) positions itself as a premium device. If you’re serious about outdoor activities and need long-lasting battery life, the Garmin’s 16 days of use without charging trumps the Galaxy’s 40 hours any day. In my testing, the Garmin’s rugged design and built-in LED flashlight make it a standout for night training. However, the Galaxy's 1.5-inch Super AMOLED display is stunning and offers features like ECG monitoring, but it requires daily charging, which can be a hassle for active users. So, what matters most here is how you plan to use the watch in your daily life.
