Enhanced Strength and Toughness The entire middle frame of the Amazfit Nexo is made of microcrystalline zirconium ceramic, which enhances strength and toughness of the device with nanoscale materials. With excellent refractive index and dispersion performance, the watch exudes a unique fruity and luster; the low thermal conductivity brings a warm and moistening jade-like tactility. The hardness is four times that of aluminum alloy, so it easily resists scratches in daily use. The ceramic middle frame must be forged for two days, sintered in a high-temperature furnace at 1400°C for five days and ground with CNC for tens of thousands of times, after which it undergoes polishing and coating processes. It is polished for 35 days before it's packaged for you. Gorgeous 2.5D AMOLED Screen with 175° Curved Surface The 1.39-inch AMOLED colorful display, with PPI 326, delivers a retina-grade display.
