Amazfit T-Rex 3 Pro vs Garmin Fenix 8
The Fenix 8 costs $600 more and adds ECG, max analytics, streaming music sync, and Garmin's ecosystem. The T-Rex 3 Pro matches it on offline maps, dual-band GPS, and 10 ATM diving support, comes close on GPS battery (38 hours versus 40), and weighs 21 grams less.

The T-Rex 3 Pro adds a Grade 5 titanium bezel and buttons, sapphire glass, a 3,000-nit AMOLED display, a dual-color LED flashlight, and a speaker for Bluetooth calls to Amazfit's rugged line, and it's the first T-Rex in a smaller 44mm size. You still get dual-band GPS, offline maps, 10 ATM water resistance with diving to 45 meters, and up to 25 days of battery on the 48mm model. It costs over $100 more than the regular T-Rex 3, and like the rest of Amazfit's lineup it has no ECG.
The Fenix 8 folds the old Epix line into Garmin's toughest case, adding a speaker and mic for calls plus genuine smartwatch-level interactivity. It's an outdoor watch first, but the running analytics underneath are as good as Garmin gets.
