CMF Watch 3 Pro Review: The Budget Smartwatch That Finally Feels Grown Up

Priced at ₹7,999 in India, the CMF Watch 3 Pro sits in an increasingly competitive smartwatch segment where brands are trying to deliver premium-looking hardware and feature-packed experiences without crossing into flagship territory. What makes the Watch 3 Pro interesting is that it doesn’t aggressively chase flagship smartwatch ambitions. Instead, CMF by Nothing focuses on delivering the things that matter most to everyday users: a stylish design, smooth AMOLED display, reliable fitness tracking, excellent battery life, and a software experience that feels cleaner than most budget wearables. And in many ways, it succeeds. But it also reveals the compromises that still separate budget smartwatches from true premium wearables.

Design & Display

The CMF Watch 3 Pro looks far more expensive than its asking price suggests. Like most products from CMF by Nothing, the watch follows a minimalist industrial design language with a circular aluminium body, subtle detailing, and a single rotating crown that doubles as a button. The Dark Grey variant, in particular, gives the watch personality in a market dominated by generic black smartwatches. It feels youthful without looking toy-like. The lightweight construction also makes it comfortable for all-day wear despite the larger size.

However, the larger 1.43-inch design is a double-edged sword. The bigger display definitely improves readability and makes navigating menus easier, but users with smaller wrists may find the watch slightly bulky over extended usage. I always love it when a watch seamlessly wraps around the wrist, but the case here is that it juts out on both ends. One controversial change is the removal of the swappable bezel system from the Watch Pro 2. That modular approach gave the previous generation a sense of uniqueness and customisation that helped it stand out. Without it, the Watch 3 Pro feels more refined but also slightly safer and less playful.

The AMOLED display itself is excellent for the price. The 1.43-inch panel delivers deep blacks, vibrant colours, sharp text, and smooth animations thanks to its 60Hz refresh rate. Unlike many budget watches that feel sluggish while scrolling, the Watch 3 Pro feels responsive and fluid throughout daily usage. Outdoor visibility is decent rather than exceptional. With brightness levels hovering around 650–670 nits, the display remains usable outdoors, but direct sunlight can still make the always-on display difficult to read quickly. Still, for ₹7,999, this is one of the better-looking smartwatch displays currently available.

Functionality

The CMF Watch 3 Pro performs best when treated as a practical smartwatch rather than a miniature smartphone replacement. For daily essentials, it handles things well. Notifications arrive reliably, Bluetooth calling quality is surprisingly usable, and the rotating crown adds a tactile interaction method that genuinely improves navigation. The built-in microphone and speaker are good enough for quick calls indoors or in moderately noisy environments.

Fitness tracking has improved considerably over previous CMF watches. The upgraded heart-rate sensor and dual-band GPS make workout tracking noticeably more reliable, especially during running and cycling sessions. GPS lock times are quick, route tracking feels accurate, and casual fitness users will likely find the health data more than sufficient. The watch supports over 130 workout modes along with heart-rate tracking, SpO2 monitoring, sleep tracking, stress monitoring, guided breathing, and AI-powered fitness coaching.

Integration with services like Strava, Apple Health, and Google Health Connect also adds some ecosystem flexibility. But the software experience still carries some rough edges. The Nothing X app is cleaner than many companion apps in this segment, but it still lacks the refinement and reliability of more mature ecosystems from Apple, Samsung, or Garmin. Occasional syncing inconsistencies, delayed notifications, and minor bugs prevent the experience from feeling completely polished.

The smartwatch also lacks a true app ecosystem. There’s no NFC for payments, no downloadable third-party apps, and limited smart integrations beyond the basics. That means the Watch 3 Pro feels more like an advanced fitness smartwatch than a true Wear OS competitor. Its IP68 rating also sounds stronger on paper than in practice. While it can comfortably survive rain, sweat, and accidental splashes, CMF itself doesn’t heavily position it as a swimming-first wearable, which feels slightly limiting compared to some rivals.

Battery Life

Battery life is easily one of the CMF Watch 3 Pro’s biggest strengths. In normal usage involving notifications, health tracking, workouts, and occasional calling, the watch comfortably lasts between 8 and 12 days, depending on usage intensity. That’s a huge advantage over many premium smartwatches that require charging almost every night. Even with GPS-heavy workouts and Bluetooth calling, endurance remains impressive. Enabling the always-on display significantly reduces battery life to around 3–4 days, but even then, it remains respectable considering the large AMOLED panel and 60Hz refresh rate.

Charging takes roughly 90 to 100 minutes through the included magnetic charger. More importantly, the battery life changes how the watch feels psychologically. Unlike Wear OS devices that constantly make you aware of battery percentages, the CMF Watch 3 Pro fades into the background like a traditional watch — something you wear daily without constantly thinking about charging.
