Suunto Run
Score: 78/100Rankings
The Amazfit T-Rex 3 is a rugged outdoor smartwatch featuring a 27-day battery, dual-band GPS with offline maps, and a 2000-nit AMOLED screen. Its bulkier case and limited app ecosystem are notable trade-offs. Best suited for hikers, freedivers, and adventure seekers who value durability and navigation over a slim profile.
The Suunto Run is a lightweight GPS sports watch aimed at runners, offering a crisp AMOLED screen, dual-band GNSS and up to 20 hours of GPS battery. Its limited GPS accuracy, lack of maps and modest music storage may deter power users. Ideal for beginner to intermediate runners who value comfort and basic training metrics.
