Amazfit Stratos 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.
