Design & Build Quality

One of the most attractive aspects of the Fire-Boltt Infinity smartwatch is its design.

This smartwatch has a large round face with two function buttons (one for the menu and the other for sports modes) and a crown button.

The interesting thing is that its crown is fully functional, which you can use to change watch faces or scroll through menus.

On the backside of the smartwatch, you will find a charging point and sensors.

Fire-Boltt Infinity Design Overview

The best thing about the Fire-Boltt Infinity is that it comes with a premium metallic frame that provides solid build quality.

The smartwatch also features soft silicone straps that can be easily replaced with any other quick-release strap.

In short, the Fire-Boltt Infinity leaves no stone unturned in terms of design and build quality and turns out to be a great pick.

Display & UI

The Fire-Boltt Infinity boasts the largest display of any round dial smartwatch, with a massive 1.6-inch round display that offers the best resolution in its segment at 400×400 px.

Fire-Boltt Infinity Display

Although you do not get to see an AMOLED display in this smartwatch, which can prove to be a deal breaker for many.

But the good thing is that due to the high resolution, you will not see that much difference in it, even when using custom watch faces, you should still be able to enjoy sharp image quality.

Another notable feature of the Fire-Boltt Infinity’s display is its slim bezels, which give the smartwatch a sleek and modern look.

The minimal bezels also contribute to a better viewing experience, as they allow for a larger screen area within a compact form factor.

In addition to its slim bezels, the Fire-Boltt Infinity has a high brightness level of 500 nits.

This makes it easy to use the smartwatch outdoors, even in bright sunlight.

Along with this, its wake gesture also works perfectly, as soon as you twist the wrist, the display turns on.

On the other hand, the company has provided a refresh rate of 60Hz for this smartwatch.

And we have seen the advantage of a 60Hz panel in smartwatches like the Noise Colorfit Pro 4 Alpha, which can provide a very smooth UI.

By swiping down on the display, you can access the control panel, which is divided into multiple pages.

Swiping up will bring up your notifications while swiping left or right will bring up the widget section, which displays your health parameters and other useful widgets like music controls.

To access the menu, you can use the menu button located on the side of the watch.

You can choose from eight different menu styles, making it easy to find a look that works for you.

Watch Faces

In Fire-Boltt Infinity, you are allowed to use more than 200 watch faces.

You will be very happy to know that this smartwatch has around 110 built-in watch faces which mean, you will be able to change them directly from the smartwatch.

At the same time, you will also get to see more than 100 cloud-based watch faces in its companion app.

One of the standout features of the Fire-Boltt Infinity smartwatch is its ability to use any of its watch faces as an always-on display.

Fire-Boltt Infinity Always-On Watch Faces

To the best of my knowledge, this feature is not available on any other smartwatch, making the Fire-Boltt Infinity a unique and innovative device.

Using the always-on display feature will likely cause the smartwatch’s battery to drain more quickly, so you may need to charge the smartwatch more frequently.

In addition to the watch faces that come pre-installed on the Fire-Boltt Infinity, you can also create your custom watch faces using the smartwatch’s app.

This allows you to fully personalize your smartwatch and make it your own.

Bluetooth Calling & Notifications

The Fire-Boltt Infinity is one of the best Bluetooth calling smartwatches with a round dial that claims to provide you with the best calling experience in its segment.

It offers a range of useful features for managing calls.

Fire-Boltt Infinity Bluetooth-Calling

When you receive an incoming call, you can accept, reject, or mute the call from the smartwatch.

During an active call, you can cut the call, mute, and control the volume.

One feature that is missing from the calling function is the ability to transfer calls.

This means that you will not be able to transfer an incoming call to your phone.

This smartwatch also provides you the feature of saving multiple contacts which is a great thing.

It also allows you to receive notifications from all of your social media apps, and you can customize which notifications you want to receive.

This means that you can stay up-to-date on your social media activity even when you’re away from your phone.

However, you can only view the notifications on the smartwatch, rather than being able to respond to them directly.

Health Monitoring

In Fire-Boltt Infinity, you get to see all the health parameters including, heart rate monitor, SpO2 monitor, sleep monitor, and meditative breathing.

Fire-Boltt Infinity Health Monitoring

It is the first ever smartwatch to provide dual heart rate monitoring which supports static & dynamic heart rate monitoring with a VC32 chipset.

This will give you better heart rate monitoring.

I have also compared this smartwatch with medical equipment, it is capable of providing good accuracy in terms of both heart rate and blood oxygen.

Although you may occasionally see an inaccuracy, so keep in mind that you should not use it for medical purposes.

Sports Modes

The Fire-Boltt Infinity includes more than 300 sports modes, which is an impressive range of options for tracking your activities.

Whether you’re interested in running, cycling, swimming, or any other type of sport, you’re likely to find a mode that suits your needs.

One aspect of the Fire-Boltt Infinity smartwatch that may be disappointing to some users is its water resistance rating of IP67.

As a result, you may need to be more careful when using the smartwatch in wet conditions.

Given that the Fire-Boltt Infinity includes more than 300 sports modes, it might have been nice for the smartwatch to have a higher water resistance rating that would allow it to be used for a wider range of activities.

Well, it cannot be denied that the Fire-Boltt Infinity is the best in the segment in terms of sports modes.

Music Storage

In Fire-Boltt Infinity, you get to see 4GB of internal storage, which makes it the most unique smartwatch in this segment.

Although you can see this feature in Fire-Boltt Visionary as well, this smartwatch gives you much bigger storage than that.

Due to this, you can store all your favorite songs and enjoy them without a smartphone.

Fire-Boltt Infinity Music Storage

Apart from this, you are also allowed to connect your TWS earbuds which I think is a very convenient feature.

Battery Life & Charging

The Fire-Boltt Infinity smartwatch has a battery life of up to 7 days under typical usage conditions.

However, if you use features like Bluetooth calling and the always-on display heavily, you may need to charge the smartwatch more frequently.

It does not support fast charging and it takes about 2 hours to charge.

App Functionalities

Fire-Boltt has finally launched its own app: FB Invincible Plus.

This app allows you to connect the Fire-Boltt Infinity smartwatch to your phone.

If you need help, then please see our guide on how to connect a Fire-Boltt smartwatch to a phone.

On the home page of the app, you will find options to view your daily step count, calorie details, and other health parameters.

Additionally, the app includes a dedicated section for GPS tracking, which allows you to use the in-app GPS to track the distance and route of your outdoor runs.

Fire-Boltt Infinity App Interface

It also allows you to customize the rest of the smartwatch’s settings and user profile.

Other Features

The Fire-Boltt Infinity smartwatch includes a range of other basic features like camera control, music control, calculator, alarm, reminders, and voice assistant.

In this, you have also been given 5 built-in games which makes it one of the best smartwatches with built-in games on the market.

Overall, the Fire-Boltt Infinity offers a wide range of features that make it an excellent choice for those who are looking for a feature-packed smartwatch.


In our opinion, and based on our tests, if you want to go for a premium round dial smartwatch then Fire-Boltt Infinity is the best choice.

In this, you get to see all the features that you can expect in this budget segment.
