boAt Wave Call 2 Overview
The boAt Wave Call 2 is a Bluetooth calling smartwatch designed around a large 1.83-inch HD display and boAt's Crest OS+ software platform.
The watch is aimed at users who want basic smartwatch functions, health tracking, activity monitoring and Bluetooth calling without moving to a more expensive smartwatch platform.
boAt lists support for 700+ active modes and 1,000+ watch faces on its current product page.
1.83-inch HD display, Bluetooth calling, Crest OS+, 700+ active modes, 1,000+ watch faces, health tracking and a 230mAh battery.
Display: 1.83-inch HD Screen
The Wave Call 2 features a 1.83-inch / 4.64cm HD display. The large rectangular screen is designed to provide more room for watch faces, notifications, widgets and smartwatch controls.
The display is one of the central features of the Wave Call 2, particularly for users who prefer a larger screen on a budget smartwatch.
The 1.83-inch display provides a relatively spacious interface for viewing notifications, activity information and smartwatch functions.
Bluetooth Calling
Bluetooth calling is one of the main features of the Wave Call 2. The watch can connect to a compatible smartphone and allow users to handle calls directly from the wrist.
This makes the watch useful for situations where checking the phone is inconvenient, such as during short conversations or while moving around.
Bluetooth calling depends on the watch being connected to a compatible smartphone and is not equivalent to standalone cellular calling.
Crest OS+ Smartwatch Experience
The Wave Call 2 uses Crest OS+, boAt's smartwatch software platform for health, fitness and everyday smartwatch functions.
The software environment provides access to activity tracking, health information, watch faces, notifications and other supported smartwatch features.
boAt positions Crest OS+ around its health-tracking algorithms and connected fitness ecosystem.
Health & Fitness Tracking
The Wave Call 2 includes a heart-rate sensor, blood oxygen sensor and G-sensor according to boAt's support specifications.
The watch also supports sleep-related tracking and a broad set of activity modes through its fitness software.
Health measurements from consumer wearables should be treated as general wellness information rather than medical diagnosis or clinical measurement.
Heart rate, blood oxygen, sleep and activity monitoring make the Wave Call 2 suitable for basic everyday fitness tracking.
Fitness: 700+ Active Modes
boAt's current Wave Call 2 product page highlights 700+ active modes, giving the watch a broad selection of activity-tracking options.
The large number of activity modes is intended to cover different forms of exercise and daily movement.
The watch does not replace dedicated sports equipment or professional fitness measurement systems, and the usefulness of individual modes can vary according to the activity.
Watch Faces & Personalisation
The Wave Call 2 supports a large collection of watch faces. boAt currently advertises 1,000+ watch faces for the model.
This gives users flexibility to change the appearance of the watch depending on personal preference, occasion or information layout.
Choose from a large selection of watch faces to change the appearance and information displayed on the watch.
Battery: 230mAh
The Wave Call 2 uses a 230mAh battery. boAt's current product information states up to 6 days in normal mode.
The same product information also states up to 30 days of standby time, while boAt's support page gives different figures for working time and standby.
Actual battery life will depend on display use, Bluetooth calling, notifications, health tracking and other settings.
Battery endurance varies by usage. Bluetooth calling and frequent health tracking can reduce the time between charges.
Connectivity & Compatibility
The Wave Call 2 uses Bluetooth connectivity to pair with a compatible smartphone.
boAt's support documentation lists Bluetooth 5.3 for the Wave Call 2, while the current product page specification lists Bluetooth 5.2. This is therefore an area where the manufacturer's published pages currently show different figures.
The support documentation lists compatibility with Android 7 and above and iOS 12.0 and above.
The watch requires the boAt Crest app for its full connected functionality and setup experience.
Water Resistance & Durability
boAt's support documentation lists the Wave Call 2 with an IP67 water-resistance rating.
An IP rating describes resistance under specified laboratory conditions. It should not be interpreted as a guarantee that the watch can withstand every type of water exposure, swimming activity or prolonged immersion.
Everyday Smartwatch Features
Along with health and fitness tracking, the Wave Call 2 is designed for everyday smartwatch tasks such as viewing notifications, changing watch faces and managing supported connected features.
Its large display and Bluetooth calling capability make it more focused on everyday convenience than on advanced standalone smartwatch functionality.

Feature assessment based on published specifications and product features. It is not an independent laboratory score or a claim of hands-on testing.
Final Verdict
A feature-rich Bluetooth calling smartwatch
The boAt Wave Call 2 focuses on the features that matter most for an affordable everyday smartwatch: a large 1.83-inch display, Bluetooth calling, activity tracking, health monitoring and watch-face customisation.
Its 700+ active modes and advertised 1,000+ watch faces give the watch a broad feature set, while Crest OS+ provides the software layer for health and fitness functions.
The 230mAh battery is designed for several days of normal use, although actual endurance depends heavily on calling, notifications, screen use and tracking features.
The main limitations are its dependence on a smartphone for Bluetooth calling and connected features, lack of standalone cellular connectivity and the absence of advanced smartwatch platform features such as Wear OS.
One specification point worth noting is that boAt's current product page and support documentation show different Bluetooth and battery figures. Buyers should therefore check the exact specification information supplied with the purchased unit.
