In India, the Watch 3 Pro launched at ₹7,999, putting it in the competitive budget-smartwatch segment. Recent reviews have also highlighted its larger AMOLED display, dual-band GPS, fitness features and Nothing X companion app. Business Today

Rather than treating the watch as a conventional smartwatch running a large third-party app ecosystem, it is better understood as a fitness-focused wearable with notifications, calling, health tracking and selected AI features.

CMF Watch 3 Pro: Key specifications

Specifications and capabilities can vary depending on software version and connected-device compatibility. Nothing’s official product information confirms the AMOLED display, dual-band GPS and claimed 13-day battery life. Nothing

Design and display

The CMF Watch 3 Pro uses a circular design with an aluminium frame and a physical crown on the right side.

The watch has a 1.43-inch AMOLED display with a 466 × 466 resolution. Its 60Hz refresh rate provides the visual interface for watch faces, notifications, health information and workout data.

The 47mm form factor is relatively large, so wrist size is an important consideration. Recent reviews have noted that the watch can feel large on smaller wrists. Business Today

One change from the previous generation is the removal of the interchangeable bezel system. Users who liked changing the appearance of the earlier Watch Pro 2 should take this difference into account. Business Today

Dual-band GPS

Dual-band GPS is one of the most important hardware upgrades in the Watch 3 Pro.

The watch supports L1 and L5 GPS signals and works with multiple satellite systems, including:

• GPS
• GLONASS
• Galileo
• BeiDou
• QZSS

Nothing says the dual-band system is designed to provide faster positioning and better route stability, including in dense urban areas and other challenging environments. Nothing

This makes the GPS hardware particularly relevant for people who track outdoor activities such as running, walking, cycling or hiking.

Independent reviews have also reported good GPS performance during outdoor workouts, although real-world accuracy can vary depending on surroundings, satellite conditions and the activity being tracked. mint

Fitness and health tracking

The Watch 3 Pro includes a broad set of fitness and health-tracking features.

These include:

• 24-hour heart-rate monitoring
• SpO₂ monitoring
• Sleep tracking
• Nap detection
• Stress tracking
• Activity tracking
• VO₂ max-related running information
• Training and recovery information
• Menstrual-cycle tracking
• 131 sports modes

Nothing also provides a Custom Running Coach, which can create structured running plans based on the user’s goals. Nothing

These features are intended for fitness and wellness tracking. They should not be treated as a replacement for professional medical assessment or diagnosis.

ChatGPT integration

ChatGPT is one of the more distinctive software features associated with the CMF Watch 3 Pro.

The feature allows compatible users to interact with ChatGPT through the watch and use it for tasks such as general questions and other supported requests.

However, the experience depends on the connected smartphone and software ecosystem.

Recent testing by Business Today found that ChatGPT support was unavailable when the watch was paired with an iPhone, with the feature remaining tied to Nothing OS in that setup. Business Today

This means buyers should check their phone’s compatibility before considering ChatGPT a major reason to purchase the watch.

Voice recording and transcription

The watch also provides a recording and transcription feature.

This can be useful for capturing short notes or voice information and then viewing the resulting text through the supported software experience.

Because transcription depends on the watch’s software and connected-device environment, users should not assume that every recording or language will produce identical results.

Battery life

Nothing advertises up to 13 days of battery life for the CMF Watch 3 Pro. Nothing

Actual battery life depends on how the watch is configured.

Factors that can increase power consumption include:

• Always-On Display
• Frequent GPS workouts
• Continuous health monitoring
• Bluetooth calling
• Notifications
• Higher screen brightness
• Frequent interaction with the display

Independent reviews have reported shorter runtimes under heavier use, particularly with Always-On Display and regular workouts enabled. Gizbot

Therefore, Nothing’s 13-day figure should be treated as a claimed maximum rather than an expected result for every user.

Nothing X app

The CMF Watch 3 Pro connects with the Nothing X companion application.

The app provides access to areas such as:

• Watch faces
• Health information
• Workout data
• Device settings
• Notifications
• Sports features
• Connected services

The Nothing X ecosystem also supports synchronization with platforms such as Apple Health and Google Health Connect, depending on the phone and available software features.

The companion app is important because several smartwatch functions depend on the connected smartphone rather than operating independently on the watch.

What the CMF Watch 3 Pro does not offer

The Watch 3 Pro is not intended to compete directly with full Wear OS smartwatches in terms of third-party applications.

Some limitations reported by reviewers include:

• No Wear OS
• Limited third-party application support
• No onboard music-app ecosystem comparable to Wear OS
• No NFC-based payment platform
• ChatGPT functionality can depend on the connected phone ecosystem

These limitations matter more to buyers who expect a smartwatch to function like a miniature smartphone.

For users primarily interested in fitness tracking, notifications, Bluetooth calling and battery life, the difference may be less important.

CMF Watch 3 Pro for iPhone users

iPhone compatibility deserves special attention.

The watch can connect to an iPhone for standard smartwatch functions, but some features are not available in the same way as they are with Nothing OS devices.

For example, Business Today reported that ChatGPT support was unavailable when the watch was paired with an iPhone 16e. Business Today

Therefore, iPhone users should check the latest Nothing X compatibility information before buying if AI functionality is important to them.

Actual pricing can change because of sales, offers and retailer promotions.

Who should consider the CMF Watch 3 Pro?

The Watch 3 Pro’s feature set is most relevant to users who want several functions in one budget wearable.

It may be relevant if you want:

• A large AMOLED display
• Dual-band GPS
• Outdoor workout tracking
• Long claimed battery life
• Bluetooth calling
• Health and sleep tracking
• Multiple sports modes
• ChatGPT integration on supported devices
• A simple companion-app experience

However, buyers looking for a large third-party smartwatch ecosystem should understand that the Watch 3 Pro uses a more limited software platform than Wear OS watches.

What to check before buying

Before purchasing the CMF Watch 3 Pro, check these five points:

1. Phone compatibility
Verify which features are available with your Android phone or iPhone.

2. Wrist size
The 47mm design can feel large on smaller wrists.

3. GPS requirements
If outdoor tracking is important, the dual-band GPS is one of the watch’s key hardware features.

4. Battery expectations
Treat the 13-day figure as a maximum claim. GPS, AOD and frequent health monitoring can reduce runtime.

5. App requirements
Understand which features require the Nothing X app and a connected smartphone.

CMF Watch 3 Pro: Key strengths and limitations

Final takeaway

The CMF Watch 3 Pro combines a large AMOLED display, dual-band GPS, extensive fitness tracking, Bluetooth calling and selected AI features in a budget-focused smartwatch.

Its biggest differentiators are the dual-band GPS, 131 sports modes, claimed 13-day battery life and ChatGPT integration. Nothing

At the same time, buyers should understand the platform’s limitations. The watch does not provide the broader third-party application ecosystem associated with Wear OS, and some features can depend on the connected smartphone.

The most important considerations are therefore phone compatibility, GPS requirements, wrist size, battery expectations and the level of smartwatch software functionality you need.
