Sports & Business
Brand-new, with a simple but graceful design. It's the style you want for sports or business. Stratos combines multiple materials and techniques, including 2.5D Corning Gorilla Glass, delicate minute markers, a reflective color screen that can be seen clearly even under bright sunlight, and a hand-polished ceramic bezel. Ceramic is durable enough to withstand all your daily challenges and will deliver a beautifully timeless look.

Three 316L stainless-steel physical buttons plus a responsive touch screen make it easy to control all the watch functions while the case uses a 3-D laser carbon-fiber texture throughout.

50m Water-Resistant, Safe for both Open Water & Indoor Swimming
This smartwatch comes with a 5 ATM1 water resistance rating (equal to a water pressure of approximately 50 meters or 164
feet). You can wear it while swimming in the ocean or a pool.

This premium watch features 16 different sports modes in addition to tracking for daily activities: Run, Run Indoors, Walk, Trail Run, Cycling, Indoor Cycling, Elliptical Trainer, Climbing, Pool Swimming, Open-Water Swimming, Triathlon, Skiing, Multisport, Tennis, Soccer and Jump Rope.

VO2max Fitness Analysis
Thanks to Firstbeat’s heart-rate analytics engine, you can access your cardiorespiratory fitness level in terms of VO2max. VO2max describes the ability of the body to utilize oxygen to transform nutrients into energy. With VO2max functionality you can access vital physiological information, tailored coaching guidance, gain workout motivation and benefit from the same scientifically personalized training insights used by professional athletes.
Designed for athletes who want to enhance their performance and track physiological data, we offer three important training tools:
Training Effect highlights the impact that specific activities have on the development of aerobic performance capacity
Recovery Time recommends downtime between each activity to maximize the benefit of each session
Training Load tracks the combined physiological impacts of all activities over the past seven days

Up to 5 Days Battery Life
Amazfit Stratos comes with a staggering five-day2 battery life on a single charge, saving the trouble of frequent charging. In a GPS-enabled sports mode you'll get 35 hours3 of continuous battery life, which is enough for a 100K trail run.

Onboard Music
You can listen to your favorite music as you run without having to carry your phone. Simply load your favorite music onto the watch, connect it to your Bluetooth headphones or earbuds, and you're good to go.

Amazfit Watch App 2.0
The new Amazfit Watch 2.0 app lets you synchronize data, check daily activity data and exercise records, adjust installed watch widget, import sports tracking map data and more. The App also supports the synchronization of your exercise data to third-party apps.
