Score: 83/100Rankings
Polar Unite is a lightweight 32 g fitness watch with a 4-day battery, accurate wrist-based heart-rate sensor and connected GPS, targeting beginners who want reliable activity tracking. It lacks a built-in GPS and has modest display specs, which may limit power users. Best for users prioritizing battery longevity and simple health metrics over advanced on-device storage.
The Amazfit Active 2 Premium is a round stainless-steel smartwatch with a sapphire-protected AMOLED screen and 10-12 days of battery endurance. It lacks an included USB-C charger and can suffer intermittent Bluetooth drops. Best suited for style-conscious users who value premium materials and dual-frequency GPS.
