2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerGarmin Enduro 3 vs COROS VERTIX 2S
The Garmin Enduro 3 is the smarter buy for most people due to its exceptional battery life of up to 90 days in smartwatch mode, far surpassing the 40 days offered by the COROS VERTIX 2S. If you're into ultra-endurance activities, the Enduro 3's unlimited solar charging capability could be a game-changer for your adventures in 2026. In real-world use, the Garmin's lightweight design at 2.22 oz makes it more comfortable for long days on your wrist compared to the bulkier 3.07 oz of the COROS. You'll appreciate the Garmin's built-in LED flashlight for night runs, while the COROS offers impressive GPS tracking with 118 hours of standard use, but this is not enough to sway those needing long-lasting performance and comfort.
