Amazfit's smart watch "Amazfit GTR 3"

As interest in health is growing, interest in smartwatches that can acquire body information on a daily basis is increasing.The "Amazfit GTR 3" introduced this time is a smart watch that can keep various physical information such as sleep and blood oxygen concentration for 24 hours.Let's report on usability.[Photo] The menu is displayed in large letters and icons, and the visibility is high.A classical design with a classical design that can be selected even if the icon is not in the center because it is a touch type is Zepp that manufactures and sells wearable devices in a partner company in China, China, the fourth largest smartphone -shared world.Health Corporation is a smart device brand that has been deployed since 2015.The "Amazfit GTR 3" (GTR3), which is introduced this time, is a new product that was just released on October 12 among the smartwatches of the company.GTR3 is equivalent to middle range in the three new products "GTR 3 Pro", "GTR 3" and "GTS".The price is 34,800 yen.The body size is 45.8x45.8 × 10.8mm, weighs 32g (excluding straps).The body material is an aluminum alloy, and the body color is Thunder Black and Moonlight Gray.Because it has a waterproof performance of 5ATM, there is no problem if it is rainy or shower.The main unit is equipped with a GPS, and the location information can be obtained by GTR3 alone, but there is no Wi-Fi or cellular function, so a smartphone is required for connection to the Internet.The connection with the smartphone is via Bluetooth.It is also common to the company's smart device to perform basic settings with the "Zepp" app for smartphones.The dial is 1 diameter.39 inches (about 35).Equipped with a circular AMOLED display of 3mm).The screen resolution is 326 ppi, which is easy to read even with smaller characters, combined with the large screen.In addition, the brightness is quite bright at 1,000 nits, and it is quite easy to see even in direct sunlight.More than 100 types of dials are available, and 15 new animation dials have been added compared to the previous model.In the standard, the screen is turned off in about 10 seconds, and when you raise your wrist so that you look into the dial, it is displayed, but the "Zepp" app described later is "effective status" of "screen -off".If you set to "all day", it will always change to the displayed state.In addition, if you set it to the display at all times, the entire screen will not be off, but in a certain time, the second hand and index will disappear if it is an analog clock, so that only the minute hand and the hour hand are displayed, the screen changes are as small as possible.It is a mechanism to save power.On the right side of the main unit, there is a crown (crown) on the top and a button at the bottom (if the main unit rotates 180 degrees, the crown will be on the lower left side).When you press the crown, the list of the application is displayed, and you can move the list up and down by turning it.If you find the desired app from the menu here, press the crown again to launch the app ... but it is good, but it actually returns to the dial.In other words, the press of the crown only supports the menu and the dial, and the app selection and the menu selection in the app will be tapped by tapping the screen.The touch operation itself is easy to do because the screen is large, but I think it was more intuitive to be able to select by pressing the crown (like Apple Watch).The button below is the shortcut button of the app set in advance, so I want to set the most used ones.The band comes with a mounting width of 22mm.The material is made of antibacterial silicon, resistant to sweat and so on, so it is nice to be able to use it cleanly.The band is a so -called quick lever/quick release, and has a lever on a spring stick connecting the watch body and the band, so you can easily attach and replace it by pulling the lever.On the back of the main unit, an optical sensor "6PD" for acquiring blood oxygen concentration and heart rate
