Bundle of Amazfit T-Rex 3 Rugged Military Smart Watch Black + Amazfit Helio Smart Ring, Wearable Fitness Tracker (Size 12)
Large, Bright Display: The AMOLED display can reach peak brightness of 2,000 nits; read your maps and workout data easily in any light. Night mode reduces eye strain in the dark, and Glove Mode keeps the screen responsive when wearing 2mm thick gloves.
Sleep & Recovery Coach: Monitor sleep quality, stages and breathing, plus sleep heart rate variability and resting heart rate. Wake up to a readiness score that lets you know if your mind and body are recovered, or if you need a rest.
Built for Adventure: Endure any challenge with a 316L stainless steel bezel and buttons. The military-grade body can resist 158°F heat and -22°F cold. Water-resistant to 328 Feet, the watch is great for surfing and can be used for freediving to a depth of 147 Feet.
Stress & Emotion Monitoring: For peak athletic performance, the mind is just as important as the body. The EDA (electrodermal activity) sensor monitors signs of stress and combines this data with your heart rate variability, to track your emotions.
27 Days of Battery Life: The Amazfit T-Rex 3 smart watch can last for 27 days with typical use, 42 hours in GPS Accurate Mode, and up to 114 hours in GPS Long Battery Life Mode. With some settings disabled, GPS usage can even last up to 180 hours for long hikes.
Crafted for the Best: Incredibly lightweight and made of titanium alloy, the Amazfit Helio Ring is less than 4 grams and 2.6mm. It’s the ideal sleep tracker for everyone looking to monitor their recovery in comfort, without the bulk of a smartwatch.
Free Maps & Advanced GPS: Download free global, contour, and snow maps. Track your adventures accurately with dual-band positioning, backed up by 6 satellite systems for fast connection. Get turn directions from your smartwatch as you go.
Precise Health Tracking: The ring hugs your finger for accurate heart rate, blood-oxygen and stress tracking, and curates specialized fitness data like VO₂ Max, Full Recovery Time, Training Load and Training Effect for review in the Zepp App.
