Key Features & Highlights
The Amazfit Active 3 Premium is not trying to be a sports watch that you tolerate wearing to dinner, or a dress watch that falls apart on a trail run. It is built to handle both without asking you to choose. The polished stainless steel frame weighs just 38g and sits on the wrist the way a good watch should; present enough to notice, light enough to forget.
The 1.32-inch AMOLED display runs at 466×466 resolution with 353 PPI and peaks at 3,000 nits of brightness. In direct sunlight, in low light, watching a metric tick up mid-run - everything stays readable and vivid. The display is protected by sapphire glass, which earns its place on a watch built for outdoor use.
Zepp Coach sits at the heart of the fitness experience. It adapts your training plan based on your performance and recovery, with structured guidance for 5K, 10K, half, and full marathons. Over 170 sports modes cover everything from trail running and HYROX training to swimming, cycling, strength work, and beyond. Strava, TrainingPeaks, Google Fit, and Apple Health all sync through the Zepp app.
GPS is built in with five satellite positioning systems and offline map support, so you can plan and run a route without your phone. If you stray from your path, automatic rerouting brings you back. Points of interest search and turn-by-turn navigation round out a navigation setup that is genuinely useful rather than just a checkbox feature.
Built-in Bluetooth calling means you can answer and make calls directly from your wrist through the onboard speaker and microphone. Music playback controls let you manage what is playing on your phone without reaching for it mid-run.
Health tracking runs continuously. Heart rate, blood oxygen, stress levels, and skin temperature are monitored around the clock via BioTracker technology. Sleep is tracked in detail through RestoreIQ, covering sleep stages, heart rate variability, breathing quality, and daytime naps. The BioCharge score gives you a daily read on your physical recovery so you know whether to push or pull back before your day begins. Menstrual cycle tracking, sedentary reminders, a weather widget, thermometer mode, voice memos, and DND mode fill out a feature set that covers both the serious and the everyday.
On heavy use, the battery lasts up to 7 days. On typical use, up to 12. That is the kind of endurance that means the watch keeps up with your schedule rather than the other way around.
