CMF Watch 3 Pro Full Review 2025: A Budget Smartwatch That Actually Does a Lot
Quick Take: The CMF Watch 3 Pro is Nothing's most polished affordable smartwatch yet. With a bright AMOLED display, dual-band GPS, 131 sports modes, ChatGPT integration, and up to 13 days of battery life — all under ₹7,999 — it's hard to find anything this capable at this price. But is it truly worth your money? Let's talk about it honestly.
Alright, let me be straight with you. There are hundreds of smartwatches under ₹10,000 in India right now, and most of them are pretty much the same thing — a square or round screen, heart rate sensor, some sleep tracking, and a battery that barely lasts a week. You've seen them all. So when CMF (Nothing's sub-brand) dropped the Watch 3 Pro at around ₹6,999 to ₹7,999, people naturally wondered: is this just another one of those forgettable budget watches, or is it actually something different?
The short answer? It's different. Not perfect, but genuinely different in ways that matter. I've spent a good amount of time digging through everything this watch offers — from hardware upgrades to the new AI features — and I want to share all of it with you in a way that actually helps you decide whether to buy it or skip it.
Let's get into it.
Before We Start — A Bit of Background on CMF
CMF stands for Colour, Material, Finish — and it's the budget-focused line that Nothing launched to compete in the affordable segment without diluting the Nothing brand itself. The CMF Watch Pro 2 was already a solid watch, but the Watch 3 Pro takes things a step further with a larger screen, better GPS, improved sensors, and — this is the interesting part — real AI features baked in.
The watch launched globally in July 2025 and made its way to India in May 2026. The India launch happened through Flipkart and authorised retail outlets, with an introductory price of ₹6,999 — which is genuinely impressive given what it offers. The regular price sits at ₹7,999, which is still very competitive.
Design and Build Quality — Does It Look the Part?
Let's talk about looks first, because this is where CMF usually nails it. The Watch 3 Pro has a round face, which immediately gives it a more traditional, watch-like appearance compared to the boxy designs you see on a lot of budget smartwatches.
The case is made from metal — yes, actual metal, not plastic — which is a big deal at this price point. The straps are made from liquid silicone, which means they're soft against your skin and don't irritate you even if you wear the watch to sleep. They're also removable, so you can swap them out if you want a different look.
One thing worth noting: the CMF Watch Pro 2 had this clever interchangeable bezel design that let you customise the look of the watch quite significantly. The Watch 3 Pro dropped that feature. Honestly, it's a small loss, but the overall design still looks clean and premium. Nothing went with a more refined, straightforward look this time around.
Colour options include Light Green, Dark Grey, Light Grey, and Orange. Whether you prefer something understated or a bit loud, there's a colour here for you. The Orange one, in particular, looks really sharp.
The watch feels solid on the wrist — not too heavy, not too light. You forget it's there during the day, which is exactly what you want from a daily-wear smartwatch.
Display — A Screen You'll Actually Enjoy Looking At
The CMF Watch 3 Pro features a 1.43-inch AMOLED touchscreen with a resolution of 466 × 466 pixels. That gives it a pixel density of around 326 PPI, which means text looks crisp, colours look vivid, and the overall viewing experience is genuinely good.
Peak brightness goes up to 670 nits, which is more than enough for outdoor visibility on a sunny day. The display also supports Always-On Display (AOD), which lets you glance at the time and key stats without waking the screen up fully. It's a nice quality-of-life feature.
The refresh rate is 60Hz, which is standard for this price point. Animations feel smooth in daily use — scrolling through menus, swiping between screens — all of it feels fluid without any janky stuttering.
Watch faces are another area where CMF really puts in the effort. You get over 120 watch face options, ranging from clean analog-style dials to more modern digital displays packed with information. There are also three custom watch face tools — album dial, video dial, and studio dial — so you can make things truly personal. You can store up to 7 watch faces on the watch at a time, which is a reasonable number for most people.

Health and Fitness Tracking — The Real Deal
Here's where things get interesting, because CMF made some meaningful upgrades in this area for the Watch 3 Pro.
Heart Rate Monitoring
The previous model had a decent heart rate sensor, but the Watch 3 Pro bumps things up with a brand-new 4-channel optical heart rate sensor. The way it works: more channels mean the sensor captures more light signals and detects finer variations in blood flow. In practical terms, this means better accuracy during workouts, especially high-intensity ones — and also better performance across different skin tones, which is a real-world problem a lot of budget sensors struggle with.
CMF claims the new sensor offers over 10% better accuracy during exercise and about 3.6% improvement at rest. Those numbers might seem small, but over time, especially if you're tracking your fitness seriously, they add up to more useful data.
Sleep Tracking
Sleep tracking on the Watch 3 Pro is more detailed than before. You get full sleep stage breakdowns (light, deep, REM), a sleep quality score, and enhanced tracking that even picks up naps — which is genuinely useful if you have a non-traditional sleep schedule. One thing reviewers have pointed out is that the wake-up time detection is more accurate than on competitor devices, recording the actual time you woke up rather than the time you physically got out of bed. Those are two different things, and the Watch 3 Pro knows the difference.
SpO2, Stress, and More
You also get 24/7 blood oxygen (SpO2) monitoring, stress tracking, and women's physiological health records. The watch also tracks calories burned, distance walked/run, exercise duration, and includes reminders to drink water and stand up if you've been sitting for too long. These are the basics you'd expect, and the Watch 3 Pro covers all of them well.
Sports Modes — 131 of Them
The Watch 3 Pro supports 131 sports modes. That's a lot. You've got the obvious ones — running, cycling, swimming, hiking, jump rope — and then a huge roster available through the Nothing X app. The 6-axis accelerometer helps with more accurate motion tracking across all these activities.
There's also 7-type automatic activity recognition, meaning the watch can detect what you're doing on its own — whether you start a run or hop on a bike — without you having to manually select a mode. Convenient for people who just want to move without fiddling with their watch.
GPS — Finally Fixed, and Then Some
This deserves its own section because GPS performance was one of the biggest complaints about the CMF Watch Pro 2. Users would wait a long time for GPS lock, and accuracy wasn't always great either.
The Watch 3 Pro addresses this directly with a dual-band GPS setup — both L1 and L5 frequencies — along with support for five satellite navigation systems: GPS, GLONASS, Galileo, BeiDou, and QZSS. What this means in practice is much faster GPS lock and much better accuracy, especially in challenging environments like dense urban areas or areas with lots of tree cover where single-band GPS tends to struggle.
Reviewers who tested the GPS in real outdoor conditions confirmed that the signal acquisition issue from the previous model has been fixed. If you're a runner or cyclist who relies on accurate route tracking, this upgrade alone might be the reason to get the Watch 3 Pro over the older model.
AI Features — Smartwatch Gets Smarter
This is where the CMF Watch 3 Pro genuinely stands out from the budget crowd. Most affordable smartwatches offer basic features and call it a day. The Watch 3 Pro actually brings real AI functionality to your wrist.
ChatGPT Integration
Yes, you read that right. The CMF Watch 3 Pro supports ChatGPT integration. You can ask questions, get answers, and interact with AI directly from your wrist. This works through Bluetooth connected to your phone, but the fact that it's available at this price point is remarkable. It's the kind of feature you'd expect to see on much more expensive wearables.
AI Running Coach
For runners, this is a big deal. The watch includes an AI-powered running coach that provides personalised training plans based on your data, recovery insights, training load analysis, and endurance predictions for distances like 5K and 10K. It also generates AI post-workout summaries, so after your run, you get a digestible breakdown of how you performed and what to work on next.
Guided Breathing and 3D Warm-Up Guides
You also get guided breathing exercises for stress relief and 3D animated warm-up guides that walk you through proper pre-workout stretching right on your watch screen. These might sound gimmicky, but they're actually well done and genuinely useful for people who don't always remember to warm up before exercise.
Active Score
Active Score is a new health metric on the Watch 3 Pro. It's essentially a single number that reflects your overall physical activity level for the day, calculated using heart rate data and MET values (Metabolic Equivalent of Task — basically how hard your body is working). The score updates daily and after each workout. Think of it as a simpler, more digestible alternative to VO2 Max. Similar features exist on Apple Watch and Pixel Watch, so it's cool to see it land on a sub-₹8,000 device.
Voice Notes with Transcription
You can record voice notes on the watch, and they get automatically transcribed. Useful for quick reminders when you don't want to pull out your phone. Combine this with the Bluetooth calling feature (with AI noise reduction for clearer calls) and you've got a watch that genuinely helps you be more productive throughout the day.
Bluetooth Calling — Practical and Clear
The Watch 3 Pro has a built-in speaker and microphone for taking calls over Bluetooth. You can store up to 30 contacts directly on the watch, so you can make calls without needing your phone in hand. The AI noise reduction on calls is a nice touch — it filters out background noise so the person on the other end can hear you clearly even if you're at a busy gym or outside.
The call quality, from what reviewers report, is solid for a budget smartwatch. Don't expect premium earphone-quality audio, but for quick calls, it gets the job done reliably.
Gesture Control — One-Handed Operation
New to the Watch 3 Pro is gesture control, which lets you perform actions with simple wrist movements without touching the screen. Things like answering calls, controlling music, and navigating menus can all be done with a flick of your wrist. It sounds like a small thing, but when your hands are full — carrying groceries, cooking, working out — being able to control your watch without using your other hand is genuinely convenient.
Battery Life — One of the Best at This Price
Let's talk numbers. The Watch 3 Pro packs a 350mAh battery, and here's what CMF claims:
⚡ Typical Use: Up to 13 days (step tracking, sleep, all-day heart rate every 5 minutes, 100 screen wake-ups per day)
🏃 Heavy Use: Up to 11 days (with intensive fitness tracking)
🌟 AOD Enabled: Around 4.5 days
🔌 Full Charge Time: Approximately 99 minutes
Thirteen days is a strong claim, and real-world usage will obviously vary depending on how often you use GPS, Bluetooth calling, and AOD. But even accounting for that, getting 8–10 days out of this watch comfortably is very realistic based on reviewer testing. That's a solid improvement over the Watch Pro 2, which offered about 11 days max.
The 99-minute full charge time is a bit long compared to some competitors, but given the battery life you get, you're not going to be reaching for the charger very often anyway.
The Nothing X App — Your Watch's Command Centre
The CMF Watch 3 Pro pairs with the Nothing X App 3.0, which is also the same app used for Nothing's wireless earbuds. This unified platform approach is smart — instead of managing multiple apps for different devices, everything lives in one place.
The app has a redesigned interface with improved stability and third-party integration support, including Strava, Apple Health, and Google Health Connect. If you're already in the Strava ecosystem or use Apple Health to track everything, the Watch 3 Pro slips right into your existing setup.
One important thing to note: if you're upgrading from an older CMF watch (Watch Pro or Watch Pro 2), CMF has given users until July 2026 to migrate their historical data to the Nothing X app. This includes workout records, sleep data, heart rate logs, and more — going back as far as October 2023. That's a thoughtful move that shows CMF cares about not losing your data history when you upgrade.

| Watch | Price (India) | Display | GPS | Battery | AI Features |
|---|
| CMF Watch 3 Pro | ₹7,999 | 1.43" AMOLED | Dual-band | 13 days | ChatGPT, AI Coach |
| Amazfit Active 2 | ~₹9,999 | 1.75" AMOLED | Dual-band | ~14 days | Zepp AI (basic) |
| Noise ColorFit Pro 5 | ~₹4,999 | 1.43" AMOLED | Single-band | ~7 days | Limited |
| Realme Watch S2 | ~₹5,499 | 1.43" AMOLED | Single-band | ~15 days | None |
The CMF Watch 3 Pro stands out because it's the only watch in this price range that combines dual-band GPS, ChatGPT integration, an AI running coach, and a proper metal build. The Amazfit Active 2 comes close on hardware but costs more and lacks the AI depth that CMF is offering here.
Who Should Buy the CMF Watch 3 Pro?
The CMF Watch 3 Pro is an excellent fit if you fall into one or more of these categories:
Fitness enthusiasts on a budget — If you're serious about tracking your workouts, runs, and health data but don't want to spend ₹20,000–₹30,000 on an Apple Watch or Galaxy Watch, this is genuinely the best option in its class right now.
Casual users who want more than basics — Even if you're not a hardcore runner, features like sleep tracking, stress monitoring, ChatGPT integration, voice notes, and gesture controls make this watch feel modern and useful in daily life.
Android users looking for a stylish everyday watch — The design is clean, the build is premium, and the Nothing X app experience is polished. It pairs well with any Android phone running Android 6.0 or above.
iPhone users who want a fitness-focused wearable — Yes, it works with iOS 13 and above too. While you won't get deep Apple ecosystem integration like you would with an Apple Watch, all the health tracking and AI features work perfectly fine on iPhone.
Who Might Want to Skip It
Be honest with yourself here. If you're looking for a smartwatch that runs third-party apps, responds to notifications with text replies, or has a built-in cellular connection so it can work independently without your phone — the CMF Watch 3 Pro isn't that watch. It runs on RTOS (a lightweight operating system built for efficiency and battery life), not Wear OS or Apple's watchOS. That's intentional — it's why the battery lasts 13 days — but it does mean the watch has real limitations in terms of what apps and features it can support.
If those features matter to you, you're looking at a different budget — something like the Samsung Galaxy Watch or Apple Watch Series — and a very different price tag.
