INTRODUCTION

   There are two types of wrist watches in the market available currently, mechanical and digital ones which in turn have several different sub-categories. For example, quartz and automatic wrist watches are all mechanical ones whereas digital, smart watches and smart bands all belong in the digital category (worth pointing out is that both categories also feature solar powered models). Personally i don't think that an good digital/smart wrist watch can ever compete with an good quartz/automatic wrist watch in terms of quality and elegance but due to the many technologies packed into smart watches (like heart rate sensors, vivid OLED screens, bluetooth wireless connectivity and GPS systems) they do represent a more all-around (not to mention state of the art) solution. Huami is one of the leading manufacturers of smart watches and bands in the world and today we'll be checking their Amazfit GTR 47mm Stainless Steel model.

   Amazfit is a self-brand of Huami. Huami is a biometric and activity data-driven company with significant expertise in smart wearable technology. Also, Huami is a provider of wearable technology for Xiaomi and exclusive maker of the Mi Band. Since September 2015, Huami has begun to use the brand, Amazfit, to sell smart wearable products that are not designed and manufactured for Xiaomi to address the middle to high-end market. According to the Frost & Sullivan Report, Huami shipped 11.6 million units of smart wearable devices in the first nine months of 2017, more than any other company in the world. 18.1 million units of smart wearable devices were shipped in 2017. As of March 31, 2018, a total of 56.5 million devices were shipped since Huami’s inception in 2013. Mobile Apps of Huami, Mi Fit and Amazfit, work hand in hand with smart wearable devices, which provide users with a comprehensive view and analysis of their biometric and activity data. As of December 31, 2017, mobile Apps of Huami had 56 million registered users. Huami is transforming the way individuals connect with the Internet and with each other through smart wearable technology and data-driven innovations. Its mission is to make the world more connected. On February 8, 2018, Huami was listed on the New York Stock Exchange (NYSE).

   The Amazfit GTR is currently available in two different variants that sport different diameter (47mm/42mm) and thickness (10.75mm/9.2mm) cases, AMOLED screen sizes (1.39"/1.2") and resolutions (454x454p/390x390p - 326PPI for both), lithium-polymer battery capacities (410mAh/195mAh) and material/color combinations (stainless steel, aluminum and titanium material for the 47mm version and starry black, cherry blossom pink, moonlight white, coral red and special glitter edition - made with 60 brilliant sparkle cubic zirconia Austrian crystals - colors/material for the 42mm model). Everything else however pretty much remains identical and so both variants feature heart rate optical sensors, 6-axis acceleration sensors, 3-axis geomagnetic sensors, air-pressure sensors, capacity sensors, ambient light sensors, corning gorilla 3 tempered glass with anti-fingerprint coating over their AMOLED touch screens, water resistance up to 5 ATM (50 meters), bluetooth v5.0 wireless connectivity, support for both GPS and GLONASS satellite navigation systems, 12 different sports modes (outdoor running, treadmill, walking, outdoor cycling, indoor cycling, open water swimming, pool swimming, elliptical trainer, climbing, trail running, skiing and exercise) and app support for both android and iOS based devices (android v5.0 and iOS v10.0 and above).
