If you want a smartwatch to pair with your Android phone, you've got a lot of options. There are Wear OS watches from a billion different manufacturers, plus Fitbits, Samsung's Galaxy Watch devices, and plenty more niche picks. This month, OnePlus tossed its hat in the ring with the creatively named OnePlus Watch. For $159, it offers quality hardware and great battery life — but crappy custom software makes using it a miserable experience.

The Good

Fit and finish The OnePlus Watch's stainless steel case and Apple Watch-style band are very nice.
Battery life Really exceptional. Expect to go a week or more between charges.

The Not So Good

No always-on display Baffling decision. Kind of limits its usefulness as a watch.
Step tracking Pretty accurate, except when it's not.
Incomplete features Doesn't fully support sleep or activity tracking at launch.
Unpolished software Feels like a rough draft. No 12-hour digital watch faces. Some typos.

Design, hardware, what's in the box

The OnePlus Watch makes a great first impression. Its round, 1.39-inch, 454 by 454 OLED screen is bright and colorful, and it's nestled in a stainless steel case, which gives the watch a nice weight. The included band is textured silicone with a clasp that's pretty obviously inspired by the Apple Watch's Sport Bands — if you're not into it, you can swap it out for any standard watch band that'll fit. Overall, the watch is a touch bigger than I'd like, but it presents as surprisingly high-quality for its price, and it feels very nice on the wrist.

There are two buttons on the side: one featuring a debossed OnePlus wordmark that functions as a power and home key, and another that can be programmed to perform a number of functions. The lack of a rotating crown is a bummer, but even without it, the OnePlus Watch sports some of the nicer hardware you can get in an Android-compatible wearable.

In the OnePlus Watch's very red, very long box, you get the watch itself, the necessary literature, and a magnetic charger.

Software, features, and battery

Unfortunately, the software here is not nearly as well formed as the hardware. The OnePlus Watch is running a custom OS that actually looks and acts a whole lot like Google's Wear OS: from the home screen, you can swipe down to access quick settings, up to see notifications, and left to get to a series of customizable tiles (swiping right, which would open the Google Assistant panel on Wear OS, doesn't do anything). Long pressing on the home screen will bring up your installed watch faces.

The selection of watch faces is, I think, fine. There are plenty to choose from in a variety of styles, and a lot of them provide easy access to additional information, like your watch's battery level and how many steps it's recorded. My biggest problem with OnePlus's faces is that all of the digital options are only viewable in 24-hour format. I know most of the world reads digital time that way, but some places don't. OnePlus says it aims to add a 12-hour option sometime this month, but that's really a feature that should have been ready before launch — a 12-hour toggle seems like it ought to be trivial to implement.

Like any smartwatch, the OnePlus Watch delivers notifications — but the way it does so is just not good. Dismissing a notification on your watch won't dismiss it on your phone, and vice versa. If you get multiple notifications from a single app (texts from two different people, for example), you sometimes can't read their contents. Replying to notifications is limited to certain apps, and you can only send canned responses. The Watch doesn't make any attempt to provide relevant options — you're limited to the same four auto-replies for every incoming message. You can't dictate or type your own, either.

The OnePlus Watch also tracks a number of health metrics, like activity and sleep duration and quality. Every edge of this functionality is rough.

To test the accuracy of the OnePlus Watch's step tracking, I wore the Watch on one arm and a Fitbit on the other for a couple of days. It seemed like it was reasonably close, as I ended the day with just a couple hundred steps more on one arm than the other. Then, as I was sleeping, the OnePlus Watch completely made up that I'd walked 4,000 steps in the span of a single hour. I asked OnePlus about this, and it's yet to provide any explanation.

OnePlus Health recommends getting 11 to 14 hours of sleep per night.

The Watch can track a number of different physical activities (just a handful for now, but a promised update next month will bring many more). It's also supposed to be able to automatically detect some activity, like walking or running, but that doesn't really work right, either. My watch consistently didn't detect that I was walking until I'd been doing it for 20 to 30 minutes, at which point it gave me a broken-English notification that read "The watch recognizes that you are walking, Select the power walking to record." My options were "Outdoor walk," "No more reminder," and "Close." After selecting that I was walking outdoors, the watch showed, among other stats, how far I'd traveled — in kilometers, despite the fact that I'd set it to display distance in miles.

One bright spot in activity tracking: you can set OnePlus Health to share your data with Google Fit, which is convenient if you're already using that platform to log your exercise.


This part of the app doesn't do anything.

If you wear the OnePlus Watch to bed, it'll track your sleep — but, at launch, all it can do with that data is show you on the watch itself how you slept the previous night. You can't view past nights on your wrist, and data isn't imported to the OnePlus Health app, despite there being a section for historical sleep data. With these limitations, sleep tracking is effectively useless. The app also recommends getting 11 to 14 hours of sleep per night, which I think is hilarious.

The watch generated stress data during periods I wasn't even wearing it.

Similarly useless: stress monitoring. OnePlus says the watch reads variations in your heart rate (which it automatically measures throughout the day) and "other physiological factors" to gauge how stressed you are. During my time with the watch, my stress rating has never gone above the "normal" range, which might be true, I guess, but the whole thing smacks of pseudoscience to me. It doesn't help that it generated stress data during periods I wasn't even wearing it.

Worse than all these quirks, though, is that the OnePlus Watch doesn't have an always-on display option. I can't wrap my head around this decision — not being able to consistently display the time is a pretty big flub for a watch. The functionality is "coming in a future update," according to OnePlus. But every competing product in this price range has it. Why on earth was the Watch launched without it? It's certainly got the battery to support AOD: most days, the battery level falls by less than 10 percent. You'd have to put in serious work to try to kill this thing in a week. Even cutting that longevity in half, battery life would still be great.

Should you buy it?

OnePlus Watch
5/10
No. I don't understand how the OnePlus Watch made it to market in its current state. It's a bad product.

Nothing works the way you'd expect it to: notifications are weird, activity tracking is buggy, and sleep tracking is broken. Table stakes features like 12-hour watch faces and always-on display functionality are coming in post-launch updates. There are also no third-party apps and no voice assistant.

Everything about using the OnePlus Watch makes it clear that development was either rushed, careless, or both. And that's an incredible shame, because if it worked the way it ought to, I'd love the thing: a $159 smartwatch with great hardware, great battery life, and functional software would be a definite win. But this is not that.

The OnePlus Watch experience feels like what you'd expect from one of those $30 fitness trackers sold on Amazon by brands you've never heard of: it works, mostly, but so poorly that I'd almost rather go without a smartwatch at all than use this one. After my time with OnePlus's wearable, I'm actually eager to get back to Wear OS.

Buy it if:

  • Hardware quality and battery life are literally all you care about in a smartwatch.
  • You have faith that OnePlus will fix the litany of issues the Watch has with software updates.

Don't buy it if:

  • You have any other smartwatch options (and you definitely do).
  • You expect a good experience out of the box.
