1. Large 2.01-inch display
One of the first things you notice about the Wave Sigma 3 is its large 2.01-inch HD display.
The bigger screen makes it easier to read notifications, check activity information, navigate through menus and access different smartwatch features.
For users who prefer a large smartwatch screen instead of a compact display, this is one of the Wave Sigma 3's biggest attractions.
2. Bluetooth calling
The Wave Sigma 3 supports Bluetooth calling, allowing you to make and receive calls directly from your wrist when connected to your smartphone.
It also includes a dial pad and contact functionality, making it possible to access calling features without taking your phone out of your pocket.
However, it is important to remember that Bluetooth calling requires a compatible smartphone connection.
3. 700+ sports and activity modes
Fitness enthusiasts get access to 700+ activity modes.
These include activities such as walking, running, treadmill workouts, badminton, football, basketball, tennis and yoga.
You can select the activity you want to track and set individual goals for different sports modes.
The large number of modes is useful if you want a smartwatch that can track more than just basic walking and running.
4. Heart-rate monitoring
The smartwatch comes with a built-in heart-rate sensor for monitoring heart rate.
The optical sensor on the back of the watch uses green light to estimate heart rate.
This can be useful for keeping an eye on general activity and workout-related heart-rate trends.
However, smartwatch health measurements should be treated as wellness information rather than medical measurements.
5. SpO2 monitoring
The Wave Sigma 3 also includes a blood oxygen or SpO2 monitoring feature.
The watch uses its optical sensor to estimate blood oxygen levels and allows users to check the readings directly from the smartwatch.
As with other budget smartwatches, these readings should not be considered a replacement for medical equipment.
6. Emergency SOS
Safety is another important feature of the Wave Sigma 3.
The smartwatch supports an Emergency SOS feature, allowing you to add an emergency contact through the boAt Crest app.
According to boAt's support information, the watch can initiate an SOS call by long-pressing the side button.
This can be particularly useful when you need to contact an emergency person quickly.
7. Turn-by-turn navigation
The Wave Sigma 3 offers turn-by-turn navigation, allowing you to receive directions on your wrist.
The navigation system displays direction arrows rather than a full map. Directions are set through the boAt Crest app and then sent to the watch.
This can be convenient when walking or travelling and you want quick directions without repeatedly checking your smartphone.
8. Live sports updates
Sports fans get another useful feature with live sports updates.
The watch can display live cricket scores, allowing you to keep track of matches directly from your wrist.
This is a nice addition for users who frequently follow cricket but do not want to keep checking their phone for score updates.
9. Built-in QR Code Tray
The QR Code Tray is one of the more unusual features of the Wave Sigma 3.
You can add QR codes from supported apps to the watch through the boAt Crest app. These can include things such as metro tickets, bus passes, UPI-related codes and social-app QR codes.
Once added, the QR codes can be accessed from the smartwatch when needed.
10. Built-in games
The Wave Sigma 3 also includes built-in games for entertainment.
These can be useful when you have some free time and want something simple to do directly from your smartwatch.
Naturally, the gaming experience is designed for casual entertainment rather than smartphone-level gaming.
11. Sleep monitoring
The smartwatch includes sleep monitoring, allowing users to track their sleep duration.
The feature is part of the watch's broader activity and wellness tracking system.
If you want to understand your general sleep routine, this can be a useful feature to have.
12. Breathing training
The Wave Sigma 3 includes a breathing training mode.
It provides an inhale-and-exhale pattern for a selected duration, helping users follow a simple guided breathing exercise.
It is a small feature, but it can be useful for people who want occasional guided breathing sessions during the day.
13. Music controls
You can use the smartwatch to control music playback on your connected smartphone.
This allows you to manage music without reaching for your phone.
boAt notes that music controls may not work with every music application because different apps can use different control protocols.
14. Camera control
Another useful convenience feature is remote camera control.
The watch can be used to trigger the camera on your connected smartphone, which can be handy when taking group photos or selfies from a distance.
15. Custom watch faces
The Wave Sigma 3 allows users to customize the watch face.
Through the boAt Crest app, you can choose from available watch faces and also use a personal image for a customized watch face.
This gives users more flexibility to personalize the appearance of the smartwatch.
16. IP67 water and dust resistance
The Wave Sigma 3 has an IP67 rating for protection against dust and water exposure.
This makes it better suited to everyday activities where the watch may encounter sweat, splashes or dust.
However, water resistance does not mean the watch should be treated as a dedicated swimming or diving watch.
17. Bluetooth 5.2
The smartwatch uses Bluetooth 5.2 for smartphone connectivity.
It is compatible with smartphones running Android 7.0 and above and iOS 12.0 and above, according to boAt's support documentation.
18. boAt Crest app support
The Wave Sigma 3 works with the boAt Crest app, which is used to access and manage many of the smartwatch's features.
The app handles functions such as device pairing, health data, watch-face customization, notifications, navigation and SOS settings.
This means the app is an important part of the overall Wave Sigma 3 experience.
