CMF by Nothing, the affordable sub-brand from tech disruptor Nothing, continues to impress with the CMF Watch 3 Pro. Launched in July 2025, this round smartwatch stands out in the crowded budget segment with a premium design, solid health and fitness tracking, impressive battery life, and a price tag that undercuts many competitors.
Design and Build: Bold and Premium-Looking
The Watch 3 Pro features a round aluminum alloy case measuring approximately 47 x 47 x 14.4 mm and weighing around 51g (including strap). It ditches the modular bezels of earlier models for a cleaner, more classic look with a textured bezel that adds character.
- Display: 1.43-inch AMOLED with 466×466 resolution (around 326 PPI), 60Hz refresh rate, up to 650-670 nits brightness, and Always-On Display support. The screen is vibrant, responsive, and sharp for notifications, watch faces, and quick glances.
- Straps: Standard 22mm quick-release options. Comes with a ribbed liquid silicone strap; aftermarket options are widely available.
- Durability: IP68 dust and water resistance.
- Colors: Options like Dark Grey, Light Green, Light Grey, and Orange.
The watch maintains Nothing/CMF’s signature minimalist, dot-matrix-inspired aesthetic across the UI and watch faces (over 130 available, including customizable ones).
Key Specifications and Features
- Battery: 350mAh. Up to 13 days typical use, around 10 days with AOD, or several hours of GPS/calls. Charging takes about 90-100 minutes.

Performance and User Experience
Reviews praise the Watch 3 Pro for reliable basics: accurate enough heart rate and sleep tracking for daily use, fast GPS lock, and smooth software. Bluetooth calling works well in controlled environments thanks to dual mics and AI noise cancellation. The Nothing X app offers good integration, especially with other Nothing/CMF devices.

- No advanced smart features like full app ecosystem or LTE.
Pricing and Availability
Globally priced at around $99/£99. In India (recently launched or launching around May 2026), it’s listed around ₹6,999–₹7,999 during offers.
Who Should Buy It?
The CMF Watch 3 Pro is ideal for:
