Nice watch

This is a simple and effective smart watch. It works very well with my Nothing Phone 3, and is easy to use and navigate itself. The weight feels right for a watch of its size and it isn't fatiguing or uncomfortable to wear; in fact, it's the only watch I've ever been able to comfortably sleep wearing. Usually I'd take mine off at bedtime, but I don't really notice I'm wearing it. Battery life is also good so far. As of writing this, I'm at about 48 hours of use since my last charge and the battery is 83%. I don't have always on display enabled, which probably helps a bit too. If you enjoy a minimalist style and don't need the frills of the more expensive Garmin smart watches this will probably be a good fit for you. Read more

Great Watch, But Doesn’t Sync with Apple Fitness Rings

The watch itself is actually really nice. it feels well-built, comfortable fit to wear all day, and looks great on the wrist. For the price, I think it's a solid value in terms of hardware and overall design. The item works fine with the Nothing App, and my workouts show up correctly in both that app and Apple Health. However, the Exercise ring in the Apple Fitness app doesn’t update, even though the workouts meet all the usual criteria. Permissions are set, and other activity like walking is tracked with no issues. If you’re someone who relies on closing your Apple Fitness rings, this might be a dealbreaker. I really hope they fix this in a future update, because the watch itself is great otherwise and definitely worth the money. Read more

Great smart watch

I’ve been using this watch for about one week, and honestly it’s one of the best value smartwatches I’ve tried. The screen is bright and sharp, the battery easily lasts several days, and the interface feels smoother than I expected at this price. The health tracking seems accurate enough for daily use, and the watch face options are surprisingly good. My only complaint is that some notifications can feel a bit delayed, but nothing deal-breaking. For the price, this thing punches way above its weight. Read more

Great Design, Smooth Performance, and Amazing Value

I’m really impressed with this smartwatch. The design is clean, lightweight, and very comfortable to wear all day. The screen is bright and easy to read, and the interface runs smoothly. Heart rate tracking, sleep monitor, and GPS are all accurate, and I love that it supports Bluetooth calling as well. The battery life is surprisingly good, easily lasting a couple of days with normal use. For this price, the features and overall quality are excellent. It’s a great value and works perfectly with my phone. Highly recommended! Read more

Great App, Great Battery, Great All-Around Performer

I've been a huge fan of Nothing for a while now, so I wanted to check out this watch from their CMF division. After using this Watch 3 for a while now I’m honestly impressed with how good it is for the price. The design is modern, lightweight, and comfortable enough to wear all day, even when sleeping. The display is bright and sharp, making it easy to see outdoors, and the menus are smooth with no lag. The Energy Score feature has been really helpful, it combines your sleep, activity, and recovery into one easy number, which actually makes it easier to understand how your body is doing day-to-day. Heart rate tracking, sleep monitoring, and GPS all work well and feel reliable, especially during workouts. Bluetooth calling is clear, and it’s surprisingly convenient to answer calls hands-free. And the companion app is clean, easy to navigate, and shows your health stats in a way that’s simple to understand without being overly complicated. It syncs quickly too, which is a big plus. Battery life has been excellent, easily lasting multiple days per charge. With 130+ sport modes and compatibility with both Android and iOS, it offers a ton of flexibility. If you want a smartwatch that looks great, performs well, and doesn’t come with a heavy price tag, this is a fantastic choice. Highly recommended! Read more
