boAt Wave Astra 4 Smartwatch with 1.83 Inch HD Display and Bluetooth Calling

The boAt Wave Astra 4 is built around a 1.83-inch HD display that gives notifications, calls, and watch information enough room to read at a glance. The screen measures 4.64 cm, while the functional crown makes moving through menus feel more direct — a small turn is easier than repeatedly tapping around the display.

Bluetooth Calling from the Wrist

With Bluetooth 5.4 and Bluetooth calling, the watch lets you make and receive calls without reaching for your phone every time. It’s especially handy during work, walking, or other moments when the phone is somewhere in a pocket or bag. Notifications for calls, messages, and apps can also appear on the watch.

Health and Fitness Tracking

The Wave Astra 4 includes 24/7 heart rate monitoring and blood oxygen tracking, along with multiple sports modes and auto activity detection for walking and running. These features make it suitable for routine fitness checks rather than requiring a separate device for every small activity.

Battery That Handles the Week

A 300mAh battery provides up to 7 days of working time, while charging takes up to 1 hour and 50 minutes. The magnetic charging cable keeps the charging process straightforward, and the watch itself weighs 43.8g, so it remains fairly easy to wear through a normal day.

Metallic Finish and IP68 Protection

The premium metallic finish gives the Wave Astra 4 a more structured look on the wrist, while its IP68 water resistance provides protection against dust, sweat, and water splashes. You notice this sort of protection mostly when workouts get sweaty or the weather changes unexpectedly.
