Xiaomi's sub-brand Huami has launched the Amazfit X smartwatch through crowdfunding platform Indiegogo. The new wearable features a curved AMOLED colour screen with a 92-degree arc, offers 9 sports modes and is capable of measuring blood oxygen levels. It lacks any physical buttons and instead seems to come with a 3D Touch-style approach for navigation purposes. There's also a 2,000mAh battery powering the smartwatch. The Amazfit X retails at $329, but Indiegogo users can purchase it for as low as $149.
