Design and Build Quality

The Mibro C3, the latest offering from Mibro, continues the tradition of combining style and sturdiness. At first glance, the Mibro C3 may appear quite familiar to those who have encountered its predecessor, the Mibro C2. The design language remains consistent, but there are subtle differences that make the C3 stand out. The Mibro C3 maintains its square watch face, which is a popular choice among smartwatches. It strikes a balance between a classic watch design and modern smartwatch functionality.

The combination of the square face and the raised frame gives it a unique character. Yes, as you heard. One notable change in the design is the more prominent frame. The frame now boasts a slightly raised profile, which not only adds to the aesthetics but also provides added protection to the watch face. This design choice makes the C3 feel more robust and secure.

Also, the watch maintains the use of polycarbonate (commonly known as plastic) for its frame, consistent with the C2 and A2 models. This choice helps keep the watch lightweight and comfortable to wear. However, the top section of the watch is made from metal, which reinforces durability. While the Mibro C3 predominantly uses plastic for its construction, it doesn’t feel cheap or flimsy. The plastic materials are well-matched, and the metal top section adds a sense of durability to the watch. One aspect that reflects positively on the build quality is the physical button on the side of the watch. This button feels responsive and adds to the overall user experience.

Understanding the dimensions and weight of a smartwatch is crucial for comfort and practicality. The Mibro C3 strikes a balance between screen size and wearability. The watch measures 47mm in diameter, 39.5mm in width, and has a thickness of 11.4mm. These dimensions make it suitable for a wide range of wrist sizes, ensuring that it doesn’t feel excessively bulky. Weighing in at just 45 grams, so, is exceptionally light. This featherlight design ensures that wearing the watch for extended periods doesn’t result in discomfort or fatigue.

The underbody of the Mibro C3 contains basic components, including sensors such as heart rate and SpO2 sensors for health tracking. It also houses the two-pin charging port, which offers a convenient and secure method of recharging the smartwatch. These sensors, combined with the microphone and speaker, enable a wide range of features. This addition allows for audio playback and even the ability to take phone calls directly from the watch.

The strap design of the Mibro C3 closely resembles that of the Mibro A2. Offers textured patterned straps with a slightly grayish tone ensuring that the watch remains firmly in place on your wrist, even during vigorous physical activities. These straps deviate from the plain and conventional strap designs commonly found in other smartwatches. Also provides a comfortable and secure fit and it’s easily replaceable with a 22mm QuickFit system, allowing users to customize their look. While the straps are made from plastic, they feel durable and well-constructed.


Before we dive into the specifics of the Mibro C3’s waterproofing, it’s essential to grasp the significance of water resistance ratings. The C3 boasts a rating of 2 ATM, which is durable and resistant to water at a depth of up to 20 meters. In simple terms, it allows the watch to withstand splashes, rain, and even brief immersion in shallow water. While it’s not meant for deep-water adventures, it’s perfect for those who want a smartwatch that can keep up with an active and sometimes wet lifestyle.

Also, If you have a leather or metal strap on your Mibro C3, it’s advisable to switch to a waterproof band for water-related activities. To ensure the longevity of your C3’s water resistance, it’s a good practice to rinse it with fresh water and dry it thoroughly after exposure to saltwater or chlorinated water. Given that the watch features a speaker and a microphone, it’s advisable to err on the side of caution and avoid exposing it to water whenever possible. By following these precautions, you can enjoy the Smartwatch for an extended period without concerns about water-related damage.

Display Quality

One of the key factors that can significantly enhance the user experience is the display quality. The Mibro C3, a budget-friendly smartwatch comes equipped with a TFT display. While TFT technology isn’t as advanced as AMOLED or IPS, it has its own set of advantages, especially in budget-friendly devices which is this display known for their durability and efficient power consumption, making them a sensible choice for a smartwatch.

The C3 boasts a 1.85-inch TFT display with a resolution of 240 x 284 pixels. This size is quite suitable for a smartwatch, offering a good balance between readability and device compactness. The resolution, while not the highest in the market, provides clear and crisp visuals on the relatively small screen. One of the standout features of the Mibro C3’s display is its brightness. It offers excellent visibility even in outdoor, well-lit conditions. Whether you’re checking your notifications while on a sunny day walk or glancing at your workout stats during an outdoor jog, the screen remains easily readable. This is a valuable characteristic of a device designed for active individuals.

The Mibro C3 incorporates a 60Hz refresh rate for its display. This means that the screen refreshes 60 times per second, resulting in a smoother and more responsive user experience. Navigating through menus, tracking your workouts, or interacting with notifications feels fluid and seamless. The 60Hz display sets it apart from many other budget smartwatches that often feature lower refresh rates.

However, it’s essential to note that, due to its TFT nature, the Mibro C3 has some limitations when it comes to its “Always-On Display” (AOD) feature. Unlike AMOLED displays, which can provide an uninterrupted AOD with many dials, the C3’s AOD has its restrictions and is subject to a time limit. After a certain duration of inactivity, typically around 20 minutes, the AOD will turn off automatically, Also, I would have liked more Always On display options, but it has just two dials. You can choose between two different styles: an analog clock or a digital clock. This mode ensures you can check the time without fully waking the watch.

Additionally, it consumes a relatively higher amount of energy compared to the original AOD found in AMOLED displays. While this isn’t a deal-breaker for most users, it’s something to keep in mind if you’re concerned about battery life and prefer an AOD that remains active continuously. Despite these limitations, the Mibro C3’s overall display quality and smooth operation more than compensate for any minor drawbacks in the AOD feature.

Comparison with Mibro A2

For those familiar with the Mibro A2, it’s worth noting that the Mibro C3’s display quality exhibits some notable differences. While both models utilize TFT displays, the C3 seems to offer a smoother and more responsive screen experience. Users have reported that transitions and animations are noticeably improved on the C3, thanks to the 60Hz refresh rate.

The watch faces themselves are visually appealing, with some resembling high-quality AMOLED displays, despite the Mibro C3 using a TFT screen. One of the C3’s notable strengths lies in its diverse selection of pre-installed watch faces or download additional ones via the Mibro Fit app. This allows you to personalize your watch’s appearance to suit your style or mood.

Whenever you receive a call on your smartphone, your smartwatch vibrates gently to alert you. The watch’s screen displays the caller’s name or number, allowing you to decide whether to accept or reject the call, all without taking your phone out of your pocket.

The Mibro C3 extends its notification support to a wide range of apps, from social media platforms to email clients.

Swiping through these notifications is effortless, giving you quick access to the latest updates from your favorite apps. You can choose which apps are allowed to send notifications to your smartwatch, ensuring that you’re only alerted to what matters most to you.

One of the benefits of a smartwatch is its ability to synchronize notifications with your smartphone. The Mibro C3 excels in this regard, ensuring that when you read or dismiss a notification on your watch, it reflects the same status on your smartphone. This synchronization means you’re always up to date, whether you’re using your phone or your watch. There are times when you need peace and quiet. The Mibro C3 offers a “Do Not Disturb” mode that lets you silence notifications during meetings, sleep, or any other time you don’t want to be bothered.

Making and Receiving Calls

The Mibro C3 stands out from the crowd by offering a seamless calling experience. While many smartwatches merely notify you of incoming calls, this watch takes it a step further – it allows you to answer your smartphone calls directly from your wrist. All you need to do is sync your smartphone with the watch via Bluetooth 5.3 and when a call comes in, a button will appear on the watch’s screen. Simply tap it to answer the call.

Sports and Fitness Features

The Mibro C3 offers a range of health and fitness tracking features, making it a valuable companion for those striving to lead a healthier lifestyle. In our assessment, the device performed reasonably well in tracking heart rate, sleep patterns, and stress levels during daily activities and workouts. While the accuracy of the C3’s tracking features is commendable for a budget-friendly smartwatch, it’s important to remember that it may not match the precision of specialized medical devices. Users should view the data provided by the Mibro C3 as informative and motivational rather than as medical diagnoses.

Heart Rate Monitoring

One of the fundamental health metrics tracked by the Mibro C3 is heart rate. The device uses its optical heart rate sensor to continuously monitor your heart rate throughout the day and during workouts. In our testing, we found that the C3 provides reasonably accurate heart rate measurements during daily activities. However, it’s important to note that, like most wrist-based heart rate monitors, it may have limitations during high-intensity activities.

During our workouts, the Mibro C3 generally performed well, providing heart rate data that was in line with readings from a chest strap heart rate monitor, which is considered the gold standard for accuracy. Nevertheless, users engaging in activities with rapid heart rate changes, such as interval training, may experience slight delays in heart rate readings.

Sleep Tracking Accuracy

Sleep tracking is another crucial feature for users looking to improve their overall health. The Mibro C3 claims to offer detailed sleep monitoring, including tracking of deep sleep, light sleep, and REM sleep stages.

In our assessment, the Mibro C3 provided useful insights into sleep patterns, including time spent in various sleep stages. Users can view their sleep data on the companion app, Mibro Fit, which provides a breakdown of sleep duration and quality. However, it’s important to remember that sleep tracking accuracy can vary between individuals, and the C3 might not be as precise as medical-grade sleep monitoring devices.

Stress Level Monitoring

The Mibro C3 features stress level monitoring, which aims to provide users with an indication of their stress levels throughout the day. The accuracy of this feature can be challenging to evaluate objectively since stress is a subjective experience. However, the device relies on heart rate variability (HRV) data to estimate stress levels.

HRV is a promising indicator of stress, with higher HRV associated with lower stress levels. During our testing, the C3’s stress level measurements appeared to align with our perceived stress levels. Nevertheless, this feature should be seen as a rough estimate rather than a precise medical measurement.

Activity and Fitness Tracking

The Mibro C3 supports various sports modes for tracking different activities and boasts an impressive selection of 70 sports modes, including running, cycling, and swimming. It also provides data on steps taken, distance covered, and calories burned during daily activities. For basic activity tracking, the Mibro C3 delivers reliable results. However, users should be aware that more advanced metrics, such as distance tracking, may not be entirely accurate, particularly in activities involving frequent changes in pace or direction. However, it lacks built-in GPS, which might be a limitation for outdoor lovers.
