Design And Build Quality

The COLMI P28 Smartwatch features a modern and elegant design that is somewhat similar to the Mibro Color. It’s designed in a square shape with a 2.5D curved screen on the sides, and a rotatable button works for page-turning, zoom in/out, back, turn on-off.

Overall, The body is slim and light made of high-quality aluminum alloy with 45.1mm large size and 8.5mm thickness and lightweight of not more than 43g, which makes it comfortable on the wrist. Also, it comes in 3 colors the same as the strap that I will mention shortly. Although it’s a budget smartwatch, you will notice the manufacturing quality is amazing, it’s one of the best budget smartwatches under $30.


If you look at the back, there’s nothing out of the ordinary, just a plastic cover with magnetic charging pins and a heart rate sensor.

The strap on this watch is made of silicone, lightweight and comfortable on your wrist for long-lasting use. You can use any 20mm belt because it’s removable and is available in Black, Pink, Silver colors.


Display Screen

The screen in COLMI P28 Smartwatch is my favorite type, it’s a large 1.69 inch TFT screen, and 2.5D curved to display better content and details, and because it has a resolution of 240*280 pixels. This is what makes it good 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.

In fact, the reason to make this type of screen my favorite, because this screen is large and takes over most of the interface, and with narrow sides, and this is only found in smartwatches with higher costs. This is in contrast to other inexpensive smartwatches that contain a touch screen, which comes in the middle of the screen and has rather wide sides. such as the COLMI P8, which had a smaller screen size and was in the middle of the body.

COLMI P28 Watch faces

In terms of Watch faces, COLMI P28 Smartwatch has many different pre-installed watch faces, you can switch between them easily in many ways, by long press on the home screen or via the Da Fit app for more watch faces with over 50 online watch faces are available for download with customization capabilities for a variety of colors, retro, analog, 3D, and digital faces or you can even use live wallpaper or your own photos as a watch face background or any wallpaper.

COLMI P28 Waterproof

With IP67 waterproof in COLMI P28 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 long or short term, however, if it’s exposed to water in any way, I prefer to dry the watch after immersing it in water and before operating it so that it stays with you for as long as possible.

Under The Hood

When it comes to performance, COLMI P28 adopts the built-in GR5515 chip for faster response speed and faster data processing. For your health, this device has an HRS3300 heart rate monitoring sensor and SC7A20 G-sensor, so this wearable device manages your motion every moment and takes good care of you throughout the day, and provides accurate heart rate measurement.


This watch has Bluetooth 5.0 So, you will not face any problems with it because it’s the fastest and most stable. And this version is compatible with Android 5.0 and later or iOS 10.0 and above so that the connection is through the Da Fit app.
