At its current price £65 this watch represents fabulous value for money. It does not have all the bells and whistles of an Apple Watch but then again it is a fraction of the price and it does come with a strap and works with IOS and Android.I love the round watch face and the general design and the good choice of watch faces available, build quality is superb as with all Nothing products, this watch works very well and battery life for me is about 4 days. A well designed well made product that I am very happy to be using.

One of the best watches for me! Very simple ‘ functionality and comfort! And the price crazy ! All the nothing product are very good for quality! The phone the headphones and the watch until now not disappointment

After really liking the predecessor to this watch, aside from the woeful GPS performance which frankly ruined it as a viable outdoor exercise solution, I was interested to see the watch 3 has improved GPS performance. I have not been disappointed so far – the GPS is fairly quick to lock on, and the accuracy seems to be very good – on par with other watches I’ve owned and used in the past. Connection seems solid, the setup is easy, and the overall suite of functionality is very good for the price point, as well as the style CMF employs. Seems to be a great watch so far 🙂

Much better than my old Fossil smart watch. Good selection of watch faces – I like analogue, and good sensors. The battery seems to last for ever (ok, not forever but for weeks wearing continuously). I changed the watch strap to something more flexible, and these are easily available. And it looks good – I think better than the smart watches that still seem to be designed around the old Casio digital watches for decades ago.

Very nice smart watch. It does everything you need. Stays connected and very light on the wrist.I bought two to use with iPhone 15 Pro Max running iOS26. It also doesn’t feel like an Android OS, it feels quite proprietary to CMF.

Great value. Incredible battery life. Beautiful screen. Only thing that lets it down slightly is the materials as the edge of the bezel on mine has scratched in a couple places already on the edge and I’ve only had it a few weeks but then its only £80! And the actual watch is brilliant. Fast nicely designed UI. Battery literally lasts weeks. Whatever magic they are doing with battery needs to go into phones.

This is a cheap smartwatch. But it does it all. Compared with the previous version, the vibration engine is much more noticeable, the GPS connects in seconds not minutes and the watch keeps connected to your phone as you wander the house. Phone calls, tracking etc work well as they did.BUT THEY HAVE STILL NOT FIXED THE TIMER despite this being only a software change. Alarms buzz repeatedly and use the loudspeaker to chime. The timer buzzes twice. That’s it and it’s easily missed IMHO. Please release an update to the firmware, Nothing 🙏 A Xiaomi S4 is only marginally more expensive..

It’s an okay product. It is a gorgeous watch I was looking to upgrade from my Fitbit to a smart watch with a little more features. I have chosen to return it however as the step count is completely off. I went for a 45 minute walk and apparently only completed 3,000 steps for the entire day, whilst my Fitbit and health app tracked 10,000.

¡Impresionante reloj por este precio!
Llevo varios días usando el CMF Watch 3 Pro y la verdad es que me ha encantado. La pantalla se ve espectacular incluso bajo el sol, el diseño es muy elegante y ligero, y la correa resulta muy cómoda para llevar todo el día.En cuanto a sus funciones, sorprende: todos los modos deportivos incluso el entrenador personal con IA que te aconseja sobre un entrenamiento totalmente personalizado, GPS de doble banda muy preciso, medición de ritmo cardíaco, sueño, oxígeno en sangre y estrés, además de una app sencilla que muestra todos los datos claramente.Muy interesante el control de la música desde el reloj.La integración de todos los datos y mediciones en la nueva app Nothing X es simplemente genial.La batería es otro punto muy fuerte: me ha durado casi 11 días con uso diario, algo que pocos relojes logran.Lo mejor: pantalla, autonomía, diseño y su sistema operativo.En resumen: un reloj completísimo y bonito por menos de 80 €.Si buscas un smartwatch fiable, elegante y con gran batería, este modelo es totalmente recomendable.

Sehr gute Uhr! Großes Lob an Nothing <3
Achtung, um ChatGPT benutzen zu können benötigt man ein Nothing Phone. Meines Wissensstandes reicht eines ab Nothing Phone 2. ChatGPT nutzt dabei den erweiterten Audiomodus, eine manuelle Texteingabe ist bisher nicht möglich. Das funktioniert aber reibungslos und ohne Probleme. Einfach in der NothingX App “Stimme von ChatGPT aktivieren” die Bestätigung setzen und ab sofort erschein ChatGPT dann in der App Liste wenn man die Krone einmal drückt.Jetzt zur Uhr, Akkudauer ist Phänomenal! Die Verarbeitung ist bei der Aluminium Brushed Version 1a, fühlt sich an wie eine richtig schöne Uhr! Das Display ist sehr schön zu bedienen, alles sehr flüssig und haptisch echt gut. Ich kenne keinen Unterschied zur Pixel Watch 3. Das UI ist übersichtlich und sehr gut gestaltet.Ein kleiner Minuspunkt wäre hier lediglich das man “nur” 116 Watchfaces hat.Insgesamt eine wahnsinns gute Uhr, für den Preis 99€ unschlagbar! Wer kein ChatGPT braucht und kein Google kann hier ohne bedenken zugreifen! Habt ihr ein Nothing Phone (so wie ich) dann ist es ein Must have!
