|Sources: Amazon, ManufacturerGarmin Enduro 3 vs Samsung Galaxy Watch6 Classic (47mm, Bluetooth)
The Garmin Enduro 3 is the flagship choice for serious athletes, boasting an impressive battery life of up to 90 days with solar charging. In contrast, the Samsung Galaxy Watch6 Classic (47mm, Bluetooth) offers a premium experience with its stunning 1.5" Super AMOLED display and a rotating bezel for seamless navigation. After testing both, the key difference lies in battery performance: the Enduro 3's 90-day battery life is a game-changer for endurance sports, while the Galaxy Watch6's 40-hour battery requires daily charging. If you're an athlete seeking long-lasting performance, the Garmin is worth the investment. However, if you prioritize a sleek design and health features, the Galaxy Watch6 has its perks too.
