Waterproof
With IP67 waterproof in HW16 Smartwatch, It means you can wear it while washing hands or on rainy days, although the watch is not approved for swimming but is good for wearing for activities, so, I do not recommend swimming or exposing it to hot water or saltwater to avoid any harm
Display ScreenThe screen in HW31 is my favorite type, it’s a large 1.85 inch IPS screen, and 2.5D curved to display better content and details, and because it has a resolution of 240*280 pixels with a high refresh rate. This is what makes it one of the best screens in a budget smartwatch in terms of size and resolution, even the sharpness of colors and brightness are so good, especially when you wear them in the sunlight you won’t be alarmed by them.
