Nothing’s smartwatch line is sold under the CMF by Nothing brand, which focuses on functional, design-led products at accessible prices. The smartwatch collection centres on the CMF Watch family, with the latest flagship-style model being the CMF Watch 3 Pro. Earlier models such as CMF Watch Pro and CMF Watch Pro 2, are also available for sale.

The range is best understood as a value-focused smartwatch family rather than a full app-platform watch ecosystem. These watches prioritise everyday health tracking, sports modes, long battery life, Bluetooth calling, phone notifications and style customisation. They are suited to users who want a capable fitness and lifestyle watch without paying premium smartwatch prices.

CMF Watch 3 Pro

CMF Watch 3 Pro is the most advanced Nothing smartwatch currently highlighted in official Nothing product website. It is positioned as a health, fitness and everyday companion watch, combining a 1.43-inch AMOLED display, built-in dual-band GPS, Bluetooth calling and up to 13 days of battery life. It is a step forward for the CMF watch line because it focuses not only on basic tracking but also on more detailed wellness insights and improved sensor accuracy.

Feature highlights

• 1.43-inch AMOLED display with a round smartwatch design.
• Built-in dual-band GPS for more reliable outdoor route tracking.
• Up to 13 days of typical battery life.
• 24/7 heart rate, blood oxygen, stress and sleep tracking.
• Improved optical sensor for more accurate heart rate readings versus earlier generations.
• Active Score uses heart rate and activity intensity to summarise weekly movement.
• Bluetooth calling with a built-in microphone and speaker.
• Nothing X app integration for watch faces, settings and wellness data.

As an everyday smartwatch, CMF Watch 3 Pro supports Bluetooth calling, phone-linked notifications and integration with the Nothing X app. The combination of long battery life and core phone companion features makes it a practical choice for users who mainly want quick information on the wrist, call handling and health tracking rather than a watch built around a large third-party app store.

CMF Watch Pro 2

CMF Watch Pro 2 is the previous-generation round CMF smartwatch and remains important because it introduced a more traditional watch-like design to the range. It is designed as a sleek round watch with an aluminium alloy body, liquid silicone straps and an interchangeable bezel system. Compared with the original rectangular Watch Pro, Watch Pro 2 feels more like a fashion-forward smartwatch while still keeping the CMF focus on affordability and long battery life.

Feature highlights

• 1.32-inch AMOLED round display with a 466 x 466 resolution.
• Aluminium alloy body with an interchangeable bezel system.
• Bluetooth calls with AI noise reduction, built-in microphone and speaker.
• Support for up to 30 contacts on the watch.
• 120 sports modes with training load, recovery time and workout effectiveness metrics.
• 3D animated warm-up exercises for selected activities.
• Multi-system GPS support for outdoor exercise tracking.
• Interchangeable strap options, including sportier silicone and more refined leather-style options depending on configuration.

Watch Pro 2 is best for users who like the CMF design language and want strong everyday fitness features, but do not necessarily need the newer health-sensor and sleep-tracking improvements promoted with Watch 3 Pro.

CMF Watch Pro

CMF Watch Pro was the original smartwatch in the CMF line. Official Nothing support material describes it as a rectangular smartwatch with an AMOLED display measuring 1.96 inches, a 410 x 502 resolution, 332 ppi and typical brightness of 600 nits. This large display made it easy to read notifications, exercise information and health metrics at a glance.

Feature highlights

• Large 1.96-inch AMOLED rectangular display.
• 410 x 502 resolution with 332 ppi and typical brightness of 600 nits.
• Bluetooth calling when paired with a phone.
• Heart rate and SpO₂ blood oxygen saturation monitoring.
• Accelerometer for movement and activity tracking.
• Built-in GPS / multi-system positioning for outdoor activity records.
• IP68 dust and water resistance rating under controlled test conditions.
• Removable strap and a large-screen interface for notifications and fitness data.

Although newer CMF watches now offer more refined design and more advanced tracking, Watch Pro remains a useful reference point for the range. It established the CMF formula: a large, bright screen, essential health sensors, Bluetooth calling, practical battery life and a price-conscious approach.

Which Nothing Smartwatch Should You Choose?

For most buyers, CMF Watch 3 Pro is the best starting point because it is the newest and most capable watch currently promoted in official Nothing product information. Watch Pro 2 remains appealing for users who value customisable physical design, while the original Watch Pro is best viewed as the foundation of the series: a large-screen, affordable smartwatch that introduced the CMF approach to wearable technology.

Choose CMF Watch 3 Pro if you want the most complete Nothing smartwatch experience currently emphasised by official Nothing product materials. It is the strongest option for health tracking, outdoor exercise and users who want newer sensor improvements, sleep analysis and built-in dual-band GPS.

Choose CMF Watch Pro 2 if design customisation matters to you. Its round shape, aluminium body, interchangeable bezel and strap options make it the most style-flexible model in the older official range, while still offering Bluetooth calling and broad fitness tracking.

Choose CMF Watch Pro if you want a large rectangular display and the essential smartwatch basics. It is the simplest model discussed here, but its big AMOLED screen, Bluetooth calling and core health sensors made it a strong starting point for the CMF watch line.
