It’s equipped with a 1.69-inch full touch screen, there is also heart rate monitoring, multiple sports modes, and most importantly it’s built-in with a speaker and microphone to make calls, all in one place for just $30, So stay with me for more details.

Design And Build Quality

The COLMI P28 Plus Smartwatch features a modern and elegant design that is somewhat similar to other Colmi P series watches. 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. Also has holes in the left part, which is the built-in speaker and microphone.

Overall, The body is slim and light made of high-quality aluminum alloy with 43.5mm large size and 11mm thickness and lightweight of not more than 45g, which makes it comfortable on the wrist. Also, it comes in 4 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 4 main colors, Black, Pink, Gold, and Silver but you can purchase colored and other shapes straps separately.


Display Screen

The screen in COLMI P28 Plus is my favorite type, it’s a large 1.69 inch IPS screen, and 2.5D curved to display better content and details, and because it has a resolution of 240*280 pixels, the resolution is normal, but it’s better than some models at the same price, however, sharpness Colors are so good even 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 Plus Watch faces

COLMI P28 Plus has some different pre-installed watch faces, and you can switch between them easily by rotating the button or via the Da Fit app with over 100 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


With IP67 waterproof in COLMI P28 Plus Smartwatch, which 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 and with the presence of a speaker and a microphone, avoiding it will be good, 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.
