OnePlus Watch is the first smartwatch from OnePlus that, as we told you in our first impressions, debuts in style with a premium design and finishes.

However, knowing the modus operandi of OnePlus and its desire to improve its products based on subsequent updates, we have decided to give it a reasonable time to assess whether this OnePlus Watch is in a more relaxed analysis.

Robust as steel and with a bright screen

One of the keys of the OnePlus Watch is the quality of its materials and its good construction based on a 316L stainless steel and polymer case for the lower area.

With a diameter of 46.4 mm and 76 grams of weight, it is not a particularly bulky or heavy smartwatch, but the choice of steel to make it more robust makes it somewhat heavier than other models made of plastic. It's an affordable tool in exchange for greater durability.

The model we have been testing sports a Midnight Black finish that features interchangeable 22 mm straps made of fluoroelastomer (a type of hypoallergenic silicone) in black with a discreet and attractive striated finish.

It's also available in Moonlight Silver, for those who prefer a lighter shade, and a limited edition Cobalt that employs even more premium materials.

The straps are appreciated of very good quality and fit perfectly to the wrist. They use a standard system of pins that do not need tools for disassembly, which opens the door to using third-party straps.

In our first impressions, we pointed out that the closing system, very similar to that of the Apple Watch, did not seem the most comfortable. As we sensed, our opinion has changed on the matter and after some practice, it is easier to put it on.

In addition, since the leftover end of the strap is hidden on the inside, it does not engage with clothes when playing sports.

At the bottom, we find the blood oxygen saturation sensors (in the center of the sphere) and heart rate (on one side) as well as the loading contacts.

The box features two right-aligned buttons that stand out just a millimeter and offer a short, solid press. OnePlus wanted to leave its particular style mark by engraved the brand name on the top button.

The function of the top button is assigned to display a list with all the options and functions of the clock, while the bottom button can be customized to launch a certain function. In our case, we have chosen to launch a quick selection of exercises to start the workouts as quickly as possible.

The screen is the most important element in a smartwatch. In this case, your choice has been a success both at the level of the hardware and the type of sapphire crystal chosen to protect it, which curves gently to cries in the box. Four months of use later, the glass looks pristine like the first day.

If we talk about the screen itself, we are facing around an AMOLED screen of 1.39 inches with a resolution of 454 x 454 pixels and a density of 326 dpi.

These values guarantee an excellent definition of texts and graphics on the screen, something to which the 775 luxes of brightness that we have measured also contributes. The watch has a brightness sensor, so it will adapt the intensity of the screen to ambient light, offering excellent visibility even in full sun.

In addition, it also has an always-on screen with several optimized dial options for those who do not want to lose sight of the time. The OnePlus Watch allows you to turn on the screen by pressing the top button or activating the wrist lift gesture to save a little more. A gesture that he quickly recognizes.

The touch behavior of the screen is really fluid and, from the main sphere, allows you to slide the different screens to access different information.

For example, swiping down displays the quick icon panel from which, in addition to setting the auto-brightness modes, you can also change it manually, activate the flashlight or set an alarm easily.

If you swipe up you will access the notifications area where you can find all the notifications and messages coming from your smartphone.

These messages are displayed briefly with a couple of lines of text, but by clicking on them they are displayed to show all the content and even, in certain apps such as WhatsApp, respond with a series of predefined responses.

We would have liked the number of applications that allow this function to be wider, or for the user to be able to edit their own predefined answers because these, in addition, contain some errors in their translation.

Among the notifications that are also received is the phone call that, in this case, you can attend from the watch itself without having to take your smartphone out of your pocket since it has a speaker and microphone.

The sound of both parts is conveyed perfectly and, as a curious note, has allowed me to take calls while still writing this analysis without audio problems.

Swiping the screen to the left displays different widgets that display basic information about heart rate, sleep recording, music player. This widget allows you to easily control both the music that is played from the smartphone and that which has been stored in the internal memory of the watch.

The ability to store music is important for a sports watch as it takes a step further in the independence of the smartphone when it comes to going out to train. With a Bluetooth connection, it's possible to pair a Bluetooth headset with your watch and listen to music untethered or take calls with more privacy.

The OnePlus Watch does not allow you to install third-party apps, but it does come very well equipped with useful applications for the practice of a sport such as a stopwatch, timer, altimeter, barometer, weather forecast, compass, and even remote shutter release for the smartphone camera.

, which would have been the icing on the cake that would allow you to go out to do sports being able to leave your smartphone at home without losing functions, or at least not need to take it out of your pocket to make a mobile payment.

110 activities, GPS, SpO2, and training detection

The software section is the one that has certainly evolved the most in the four months that we've been using it and that have made the OnePlus Watch a totally different smartwatch from the device we received after its launch.

An example of this can be found in the more than 110 activities that are currently listed, and that contrasts with the barely 30 that it brought in origin.

OnePlus Watch, review and review

Among them we find all kinds of team and track sports (basketball, football, tennis, volleyball, etc.), gym activities, indoor machines and indoor activities (bodybuilding, treadmill, stretching, yoga, swimming, martial arts, etc.), and many others outdoors (running, walking, climbing, golf, parkour, etc.).

Indeed, some of them do not cease to be curious as Walking the dog or that makes distinctions between Taichi and Chinese martial arts. Among these activities, we also find some water sports since the OnePlus has an IP68 certificate and resists 5 ATMs.

In any case, it will be difficult not to find an activity that fits your needs, although to choose one of them you must try it since there are translation errors in their names.

The OnePlus Watch has an automatic activity detection mode that detects that you have started a workout and, after a few minutes, shows you a notification to start recording the activity and, therefore, start GPS positioning if necessary.

In this sense, the OnePlus watch is very efficient detecting and pausing workouts when you stop and achieving excellent accuracy with GPS positioning.

Not so precise has been the step count and distance calculation where the Huawei Watch GT 2e— our usual control device and direct rival that we discuss here— has consistently recorded a hundred more steps and, therefore, a greater distance than the OnePlus Watch.

With the recent updates, the data record has improved and the difference has been reduced, becoming more accurate and closer to the data we obtained with the control device. So developments in this area have been considered and there is still room for improvement.

We've had fewer problems with heart rate and blood oxygen saturation sensors, which have collected data closer to reality. Thanks to the combination of these sensors the OnePlus Watch performs excellent monitoring of sleep and its phases or allows to maintain control of stress levels.

The OnePlus Watch links via Bluetooth 5.0 to the smartphone and syncs all this information with the OnePlus Health app that is only available to Android mobile users, completely excluding iPhone users.

The OnePlus Health app configures most of the watch's features and customizations, such as installing different dial designs from a growing catalog of dials of different styles, which apps will send notifications to the watch, or which music will be saved to the device's internal memory.

In addition to the designs offered in the app, the OnePlus Watch lets you customize the dials to match the color of your clothes or create your own spheres from your photos.

Aesthetically, the app maintains the OxygenOS design, with a minimalist aesthetic in which the only color notes are set by the data graphics. The app is divided into three clear sections located at the bottom.

From the Fitness section, the activity is recorded directly from the smartphone, while in Manage all the configuration settings of the smartwatch are concentrated.

The Health panel is the most important since it accesses different sections with graphs and a history of the health and activity data collected by the OnePlus Watch.

The data is divided into different panels and, when you tap on it, it unfolds to provide a view of the historical series. However, as with other similar watches and bracelets, we believe that the data is not delved into beyond offering the different variables of that measurement.

For example, the activity history displays a summary of distances, times, heart rate, etc., and displays the route on a map. However, that data is not combined to show what heart rate he had at a certain point in the course or how high he was.

It's something that shouldn't be too complicated since the clock records all those variables by showing them separately.

Direct rivals of the OnePlus Watch like Fitbit Charge 4 –analysis– or the Huawei Watch GT 2e we've mentioned before offer those features in their respective apps. One positive point is that one plus watch allows you to send that data to Google Fit.

11 days without worrying about the battery

Autonomy is another aspect in which the OnePlus Watch stands out. According to the brand, your smartwatch can stay active for up to 14 days without having to go through the charger.

We honestly thought that estimate was going to be very optimistic, but having a 402 mAh battery, basic operating system, AMOLED screen and good management of Bluetooth connections in the background make consumption stay under control.

With an approximate use of between three and four sports activities with GPS, activation, and automatic brightness on the screen, and email notifications and messaging apps activated, we have achieved 11 days of use.

If we had limited GPS in sports activities or reduced notifications, we would certainly have reached those announced 14 days without too many problems.

The charging experience goes in the same direction and OnePlus uses the same Warp Charge fast charging technology as on its mobiles. The result has been a load that reaches 50% of its capacity in just 13 minutes and completes 100% of the process in 45 minutes. That is, with 13 minutes of charging, you get about a week of use.

OnePlus has opted for a very compact USB charger that is magnetically fixed on the back of the smartwatch ensuring a good anchor in the charging contacts.

OnePlus Watch, a diamond in the rough that has evolved but has room for improvement

We don't exaggerate in the slightest when we say that the watch we pulled out of its case a few months ago has little to do with the OnePlus Watch we're looking at.

With the latest updates, the accuracy of the interface has been considerably improved thanks to the incorporation of Spanish among the available languages and in available functions.

However, despite having seen first-hand the excellent evolution of this smartwatch in its first months on the market, it seems to us that this policy of OnePlus to finish developing the device in the hands of the user is not the right one. The user pays for a wearable device from day one, not four months later.

That said, what we have left is a clock that, today, offers more lights than shadows, although it still has a lot of room for improvement.

The design and materials are of exquisite manufacture and are comparable to those of any smartwatch that costs 100 or 200 euros more. So the EUR 159 costs are justified.

At the level of functions, it is also very complete and offers an adequate level of accuracy in the records, especially considering that it is not a medical device, so its readings should only be taken as a reference, not as medical data.

Autonomy is one of its strengths and makes you practically forget that you carry a battery-powered smartwatch on your wrist, something to which the immediacy of its fast-charging also contributes.

All in all, the OnePlus Watch is an excellent smartwatch for those looking for premium quality and design without giving up a contained price and maintaining advanced smartwatch features.
