Let’s be honest—most of us want a smartwatch that does it all: tracks our health, keeps us connected, looks good on our wrist, and doesn’t drain our bank account. But finding that sweet spot between price, performance, and polish is harder than it sounds. I’ve tried budget smartwatches that feel like plastic toys, overpriced flagship models with features I’ll never use, and everything in between. So when I first heard about the CMF by Nothing Watch, I was skeptical. At just $69, could it really deliver a premium experience without cutting corners?
After using the CMF by Nothing Watch for several weeks—tracking workouts, sleeping with it on, making calls, and even taking it for a swim—I can confidently say this little device punches way above its weight. With a 4.3-star rating from over 1,500 users, it’s clear that many others feel the same. From its vibrant 1.43” AMOLED display to AI-powered health insights and dual-band GPS, this watch offers a suite of features typically reserved for devices three times the price. Whether you’re a fitness enthusiast, a busy professional, or someone just looking to upgrade from a basic fitness band, the CMF by Nothing Watch might just be the smartest $69 you’ll ever spend.
What is the CMF by Nothing Watch?
The CMF by Nothing Watch is a feature-packed smartwatch designed to blend style, functionality, and affordability into one sleek package. Developed by Nothing—a brand known for minimalist design and tech-forward thinking—this watch is part of their CMF sub-brand, which focuses on accessible, high-value consumer electronics. Despite its modest price tag, the CMF by Nothing Watch doesn’t skimp on premium features, offering everything from medical-grade health monitoring to hands-free Bluetooth calling and advanced fitness tracking.
At its core, the CMF by Nothing Watch is built around a 1.43” AMOLED display with sharp resolution and an always-on mode, giving it a premium look that rivals watches costing $200 or more. The watch runs on a custom OS optimized for efficiency and responsiveness, paired with the Nothing X App 3.0 for seamless smartphone integration. It supports both Android (6.0+) and iOS (13+), making it one of the most inclusive smartwatches in its price range.
Key specifications include:
- ✅ 1.43” AMOLED display with 466 x 466 resolution
- ✅ 4-channel heart rate sensor with 10%+ improved accuracy
- ✅ L1+L5 Dual Band GPS for precise outdoor tracking
- ✅ 130+ exercise modes with GOMORE-powered analysis
- ✅ IP68 water and dust resistance
- ✅ Up to 13 days of battery life
- ✅ Built-in mic and speaker for Bluetooth calls
- ✅ AI-powered noise reduction and voice transcription
- ✅ Women’s health tracking, hydration reminders, and posture alerts
The target audience for the CMF by Nothing Watch is broad: fitness lovers who want detailed workout data, busy professionals needing quick notifications and calls on the go, travelers who value GPS accuracy, and everyday users looking for a stylish, reliable smartwatch without the premium price. It’s especially appealing to iPhone users who don’t want to spend $300+ on an Apple Watch, or Android users seeking a capable alternative to Wear OS devices that often drain batteries in a day.
Key Features of CMF by Nothing Watch
Ultra-Accurate Health & Fitness Tracking
One of the standout features of the CMF by Nothing Watch is its advanced health monitoring system. The watch uses a 4-channel optical heart rate sensor that delivers a 10%+ improvement in accuracy compared to previous models. During my testing, I compared its readings side-by-side with a chest strap monitor during a 5K run and was impressed by how closely the data matched—especially during high-intensity intervals.
Beyond heart rate, the watch tracks SpO₂ (blood oxygen levels), stress levels using HRV (heart rate variability), and sleep with 5%+ improved accuracy. The sleep monitoring includes detailed breakdowns of light, deep, and REM sleep, plus a “sleep zone” feature that identifies optimal times to wake up based on your sleep cycle. I found this particularly useful on mornings when I felt more refreshed—even if I hadn’t slept long, the watch correctly identified that I’d woken during a light sleep phase.
The inclusion of L1+L5 Dual Band GPS is a game-changer for outdoor athletes. Unlike single-band GPS found in many budget watches, dual-band technology reduces signal interference from buildings, trees, and weather, resulting in more accurate distance and pace tracking. On a trail run through a forested area, the CMF by Nothing Watch maintained a consistent lock on my location, while my older single-band watch struggled with drift.
AI Life Companion with Bluetooth Calling
The CMF by Nothing Watch doubles as a hands-free communication device thanks to its built-in microphone and speaker, enabling crystal-clear Bluetooth calls directly from your wrist. The AI noise reduction technology filters out background sounds like wind, traffic, or office chatter, making conversations surprisingly clear—even in noisy environments.
I tested this during a walk in a busy city park and was able to take a call from my partner without pulling out my phone. The audio was crisp, and they said I sounded “almost like I was on a regular phone.” You can store up to 30 contacts for quick access, and the watch supports voice notes with real-time transcription—a feature I used to jot down ideas during a morning jog.
Gesture control adds another layer of convenience. With a simple wrist flick or tap, you can answer calls, skip music tracks, check the weather, or trigger your morning news briefing. It’s not as robust as voice assistants like Siri or Google Assistant, but for quick actions, it works reliably and feels futuristic.
130+ Exercise Modes with GOMORE Analysis
Whether you’re into yoga, swimming, cycling, or high-intensity interval training, the CMF by Nothing Watch has you covered with over 130 built-in exercise modes. Each workout is tracked using the GOMORE-powered performance analysis engine, which provides real-time feedback on metrics like aerobic and anaerobic performance, training load, and recovery time.
During a strength training session, the watch automatically detected my movements and logged reps and sets with surprising accuracy. For runners, it offers pace, cadence, elevation gain, and even suggests personalized training zones based on your fitness level. The “My Heart Rate” technology creates custom zones using your maximum heart rate, ensuring you train at the right intensity.
The 7-type motion recognition system picks up activities like walking, running, cycling, swimming, elliptical, rowing, and even dancing—without needing to manually start a workout. I was amazed when it logged my evening Zumba session after I forgot to press “start.” It’s these small touches that make the watch feel intelligent and intuitive.
Stylish Design for Every Occasion
The CMF by Nothing Watch doesn’t sacrifice aesthetics for affordability. The brushed metal finish gives it a premium, minimalist look that transitions seamlessly from the gym to the office. The 1.43” AMOLED display is bright, colorful, and highly readable in direct sunlight—something I tested on a beach vacation where other smartwatches struggled with glare.
The always-on display (AOD) feature keeps the time and key stats visible at a glance, and with 150 customizable AOD watch faces, you can match your style to your mood or outfit. I particularly loved the “minimalist digital” face for workdays and the “animated nature” theme for weekends. The interface is smooth and responsive, with no lag when swiping between apps or settings.
Despite its large screen, the watch feels lightweight and comfortable on the wrist. The silicone band is soft, breathable, and doesn’t cause irritation even after hours of wear. I wore it to bed for sleep tracking and barely noticed it was there—a rare feat among smartwatches, which often feel bulky or restrictive at night.
Pro-Grade Fitness & Health System
The CMF by Nothing Watch introduces an “Active Score” system based on MET (Metabolic Equivalent of Task) values, giving users a daily snapshot of their overall health and activity level. This score considers steps, heart rate, exercise intensity, and recovery, offering personalized insights and recommendations.
For example, after a light walk and a stressful day at work, my score dropped to 62/100, prompting a suggestion to take a 10-minute breathing exercise. The next day, after a 30-minute run and quality sleep, it jumped to 89. It’s a simple but effective way to stay accountable and motivated.
Women’s health features include menstrual cycle tracking with retrospective ovulation estimates, which I found helpful for planning and understanding my body’s patterns. The watch also sends smart reminders for hydration and posture—especially useful during long workdays. I set it to remind me to stand up every hour, and it gently vibrated without being intrusive.
Long Battery Life & Durability
Battery life is where the CMF by Nothing Watch truly shines. With up to 13 days of use on a single charge, it outperforms most competitors in its class. In my testing, I got 11 days with moderate use—Bluetooth calls, GPS workouts, sleep tracking, and always-on display enabled. That’s a huge relief compared to watches that need daily charging.
The IP68 rating means it’s resistant to dust, sweat, and water splashes, making it safe for swimming, showering, and intense workouts. I wore it during a rainy hike and a pool session, and it handled both without issue. The build quality feels solid, with no creaks or loose parts, and the screen resisted scratches from daily wear.
Seamless App Integration & Smart Features
The Nothing X App 3.0 is clean, intuitive, and packed with useful tools. It syncs effortlessly with Apple Health, Google Fit, and Strava, allowing you to consolidate all your fitness data in one place. I appreciated being able to share my runs with friends on Strava directly from the watch.
Smart features include weather updates, music control, camera shutter remote, and voice note transcription. The 3D warm-up guide is a nice touch—it walks you through dynamic stretches before a workout, reducing injury risk. I used it before a morning jog and felt more prepared and limber.
How Does CMF by Nothing Watch Perform?
Daily Wear & Comfort
In my experience, the CMF by Nothing Watch is one of the most comfortable smartwatches I’ve worn. The lightweight design and soft band make it easy to forget you’re wearing it—even during sleep. I’ve worn it for 12+ hours straight without discomfort, and the breathable material prevents sweat buildup.
The always-on display is bright enough to read in sunlight but dims intelligently at night to avoid disrupting sleep. The haptic feedback is subtle yet noticeable, ensuring you don’t miss notifications. Overall, it feels like a premium device, not a budget compromise.
Workout Tracking Accuracy
During a week of varied workouts—running, cycling, strength training, and swimming—the CMF by Nothing Watch delivered consistent and accurate data. GPS tracking was precise, with minimal drift, and heart rate readings aligned closely with my chest strap monitor. The automatic workout detection worked flawlessly, logging activities I forgot to start manually.
The post-workout analysis provided actionable insights, like suggesting a rest day after a high-training-load session. This level of feedback is rare in sub-$100 watches and shows the depth of the GOMORE algorithm.
Bluetooth Call Quality
Bluetooth calling was a pleasant surprise. The AI noise reduction effectively filtered out wind and traffic, and the speaker delivered clear audio. My contacts reported no issues hearing me, even in moderately noisy environments. The ability to answer calls without reaching for my phone added real convenience, especially when driving or cooking.
One minor limitation: the speaker isn’t loud enough for very noisy areas like construction sites, but for everyday use, it’s more than adequate.
Battery Life in Real-World Use
Battery performance exceeded expectations. With always-on display, GPS workouts, and daily notifications, I consistently got 10–12 days per charge. A full charge takes about 90 minutes, and the watch supports fast charging—going from 0 to 50% in under 30 minutes. This makes it ideal for travelers or those who forget to charge regularly.
