Microcrystalline Zirconium Ceramic Frame Polished for 35 Days.

Enhanced Strength and Toughness

The entire middle frame of the Amazfit Nexo is madę 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 Iow thermal conductivity brings a warm and moisten-ing jade-like tactility. The hardness is four times that of aluminum alloy, so it easily resists scratch-es 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 under-goes polishing and coating processes. It is polished for 35 days before it's packaged for you.
