The watch is on another level considering its price, it is the best you can get on the market right now.
The minor issues it has are that you cannot connect two watches from the same company to the same phone and that recent calls are not deleted from the watch.

5 and that's not even enough!
There is nothing better in its price category, and it's better than many watches with a higher price. I replaced my Amazfit with this after extensive market research and comparisons, because I wanted Wear OS (for real NFC) and calls. It lacks absolutely nothing, even Google Maps works. Absolutely customizable (you can even disable Sleep Mode, which I saw mentioned somewhere) thanks to the Play Store, it lacks absolutely nothing. The OHealth app could be improved, but it's still just fine!
PS: Purchased at €209.

The best! It has nothing to envy from any other band. Fast payments, calls as if you're talking from a mobile phone, and perfect appearance!

1 month owner, amazing as a watch. Functionally I have no complaints, it does everything. Speed, screen under the sun, recordings in general. Perfect. If it lasted 2-3 days on battery it would be a steal at this price.

I will start with the negatives
I did not buy it for myself
It is a gift for the godfather of the younger of my two boys

Now for the positives
Appearance, 11 / 10

Feel in hand, 10 / 10

Response speed, 10 / 10

Charging time, 10 / 10

Battery life, 9 / 10

Price, unjustifiably low for what it offers!

All that remains is to buy another one for myself and return with updates to the current review.

The best, much superior to more expensive models in the category, very satisfied with the purchase!!

Overall satisfied, I would like the battery to last longer. Attention: it does not work with iOS

I've had it for about 1.5 months and I have one thing to say... The watch is 100% worth its money and even more... The battery, with continuous connection to my phone and all notifications active, sometimes even talking through the watch, easily lasts 4 days... Also, the durability of its material is incredible... The glass is truly scratchproof and the titanium is top-notch... At this price, with eyes closed, there is simply nothing comparable... I also got the extra bracelet which fits it perfectly...

if you get used to the battery that lasts 5 days with continuous heart rate monitoring, it is very good. not perfect compared to many models I had from amazfit but it stands respectably next to them. the app needs improvements.

big watch, with many apps and functions, I think good measurements. for its price I would say it's a good deal. 4 stars because I generally keep 5 for something truly amazing.

It arrived on time! It is very good for its price! Very efficient! Very nice color, as shown in the photo for a man's hand. On a woman, it looks a bit big.

What can one say about this watch... You look for something negative and you can't find it. The screen and resolution are flawless, as is the touch response. Accurate measurements, NFC and Google Pay for payments, and of course the Play Store. The button with the crown is very convenient and practical, health measurements and ECG which most watches don't have... But the most important thing for me, and the reason I chose it over the Galaxy Watch from Samsung, is its battery... It lasts 4-5 days and you never worry about it running out of battery... With the Galaxy Watch, along with your phone, you had to charge the watch too, it never lasted more than 2 days. Not to mention always on display and workouts. There, it might not even last a day. All these problems were solved with the OnePlus

The watch is awesome guys... fast charging, satisfactory battery life, supports many apps (Spotify, email, SMS, browser, YouTube...)... it's like having a mobile phone on your wrist with somewhat limited capabilities! You can reply to all the messages you receive... you can listen to music from YouTube-Spotify, it has GPS, the NFC works perfectly, it has countless watch faces if you download its app on your phone, you can also receive calls and talk from the watch, it has a satisfactory speaker and others hear you crystal clear from what I've been told... one last and important thing, it has Google Assistant inside, Gemini, you talk to it and it opens apps and whatever else you want by itself! That's all from me! It has many measurements for workouts, sleep, health, but I haven't checked those yet!

Coming from the Samsung Galaxy Watch Ultra, I switched to this one but went back again.
Its positives are its autonomy and charging speed; from 10% or 15% it charges to 100% in 35 minutes.
However, its positives stop there. The customization from OnePlus is lacking a lot. Even when you have always-on display enabled and use various functions, a kind of screen lock appears and shows the time on a mosaic-style colored background. Also, when you sleep and wake up, the watch automatically enters a kind of sleep mode and you have to press a button and select 'end' to exit. And finally, in the stopwatch app, the location does not work even though it is selected, and it does not show the distance statistics.
In summary, the software needs a lot of work to reach the level of what you can do with wrist gestures, as well as within the menu and in functionality.

Coming from a Samsung smartwatch, I can say that the OnePlus is an amazing watch that does everything automatically by itself without you having to do anything, excellent build quality, perfect in everything, and a large battery

Beautiful smartwatch, in moderate use it seems quite good. Its measurements seem reliable, the GPS as well as the cycling workouts remain to be tested once the weather improves. Overall, a value-for-money smartwatch

A pretty good watch for its price. It sits very nicely and is comfortable on the wrist; I've worn it all day and it doesn't bother me at all. It connects very easily with the phone and I really like its strap, which seems to be of good quality (I have the 46 mm with the black strap). If you want to spend a little more money for a better smartwatch without going over budget, it is definitely one of the best choices, if not the best.

This particular watch, guys, is awesome. It has WEAR OS on it, which is top-notch... and as for battery life, although I was a bit worried, it easily lasts 4 days, maybe even 5... I highly recommend it.

Notable watch, bought it to have contactless payments with Google Pay and the truth is that it works flawlessly, premium build, beautiful and simple for Wear OS, the battery lasts quite a while, the only negative is the few watchfaces

Excellent product, with a premium feel and materials. Battery lasts 5 days if you use it on factory settings, less with AOD, close to 2 weeks if you put it on power saving. It is large and a bit heavy, even though I have a big wrist. Its functions are very good and the measurements are quite accurate. With a metal bracelet it becomes perfect. Beyond that, I remove one star because, although it states that it withstands 5 atmospheres of pressure and immersion in water/swimming, if you have damage from moisture, even due to material failure, the warranty does NOT apply and the company acts ignorant. BIG ISSUE, not that others don't do it too, but it shouldn't be allowed. Also, if you have iOS it is not compatible, so... get something else.

Excellent choice of smartwatch. Battery lasts 5 days and very high-quality construction. Looks nice on the wrist, without appearing large, I recommend it for those who want a watch with WearOS.

By far the best smart watch for this price. It outperforms others that are much more expensive. The battery is superb. If it also had a SIM, it would truly lack nothing.

Vfm phone for what it does compared to its price. Battery ~12-15% per day (without much fiddling but with respiratory problem assessment + AOD off). My issue is that when I answer from the phone, the sound (microphone and speaker) automatically goes to the watch (and you have to route it back to the phone if you want). It's probably an issue with wear os or my phone (Motorola) or incompatibility between the two. I don't know. I would like this to be fixed at some point. What I would like to see in a future model though is a) lte support b) stronger speaker and clearer microphone (indoors it's fine but with noise you have to keep it close to your ear to talk and hear the other person) c) ability to have custom tiles with any app I want (I haven't managed to do it through OnePlus, only with a 3rd party app). Otherwise, as others have said!

A VFM watch. It has a good battery compared to the competition. Because many compare them to the 2 weeks of Huawei, if you put it in safe mode it lasts over 10 days. Safe mode = all the functions that the Huawei GT series also have.
Very good indications and measurements.

Some negatives that cost it the 5 stars are:
Durability in seawater, the manufacturer does not recommend it and so I am forced to take it off every time I dive.
It does not support esim.
It is missing some sports in the activities.
I would like, since it has built-in GPS, for it to recognize my location and not require me to turn on location on my phone for the weather to update, for example.
I would like, since it is Wear OS, to have a corresponding app for Meta's Messenger or Viber as it has, for example, for WhatsApp.

It easily rivals a more expensive watch! It has Wear OS, which is rare at this price, battery autonomy of 4 full days with almost everything turned on! Fast charging from 10-100% in almost an hour! Very good screen under the sun. I haven't tested the waterproofing yet. For YouTube, premium is required, same for Spotify, which is logical and expected. The top button is handy because it's not just decorative, it helps a lot in all the watch menus. Accurate measurements.

Flawless NFC operation, the only thing you need is to add your cards to the watch.

Durable and stylish watch. The battery lasts several days compared to other smartwatches. It needs charging once every 4-5 days. You can connect it to the OnePlus charger for fast charging if you are in a hurry.

Very good choice of smartwatch! It does everything and it's worth it!

From Huawei GT 2 Pro to OnePlus Watch 3. Very good both in running conditions (its measurements are just fine) and in everyday use. Its battery is very good and lasts 5-6 days in full operation.
Finally, it is also very beautiful visually! I recommend!
