2026 comparison
Updated Jan 7, 2026
|Sources: Amazon, ManufacturerCOROS VERTIX 2S vs Suunto Vertical 2 Titanium
Get the COROS VERTIX 2S unless you need a brighter display. Its battery life is insane at 118 hours for GPS use, making it a go-to for ultra-endurance athletes. In contrast, the Suunto Vertical 2 Titanium shines with its 1.5-inch AMOLED screen at 2000 nits, but its battery offers only 65 hours in performance mode. In real-world use, a longer battery means fewer charging breaks on long adventures. The COROS VERTIX 2S keeps you powered for 40 days in daily use, while the Suunto Vertical 2 Titanium's 20-day smartwatch mode might leave you scrambling for a charger sooner than you'd like. If you're serious about your outdoor challenges, these specs could make all the difference in your choice in 2026.
