To make calls, just below the button, you’ll find the microphone, addition of holes in the left part, which is the built-in speaker.

The strap is one of the important things to complete the overall look of the watch, that’s why it is made of silicone, it’s lightweight and comfortable on your wrist for long-lasting use, and is available in colors Black, Blue, Gold, Silver, And an additional choice you can buy another from metal or leather.

Display Screen

The most prominent development of the latest smartwatches is the display, This is what makes the screen in Colmi P45 my favorite type by a large 1.81-inch TFT display, which makes it one of the best screens from the brand if you compare it to any previous version like COLMI P28 Plus, the difference may be up to 0.12 inches, And from this, you notice that the chin of the edges is very narrow than before, even the glass is 2.5D curved to display better content and details.

If you think we’re done, you’re wrong because the screen is perfect and that’s what makes it a pivotal selling point. The resolution is perfect with a high refresh rate and this makes it more attractive in the hand. Definitely, it’s 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, It won’t be much different if you wear it under the sun. And as I always say, the reason makes this type of screen my favorite is that large and takes over most of the interface, and with narrow sides, and this is only found in smartwatches with higher costs.

Multiple Watch Faces

Without watch faces, the fun wouldn’t be complete, that’s why Colmi P45 brings you 11 different pre-installed watch faces with static and dynamics dials, you can switch between them easily in many ways, by rotating the button or via the Da Fit app for more watch faces with over 100 online watch faces are available for download and some watch face dials are free, while some need to be paid. and it’s included a variety of colors, retro, analog, 3D, and digital faces, or you can even use your own photos as a watch face background or any wallpaper and have the possibility of customization.
