The OnePlus Watch is a great first smartwatch from OnePlus, blowing pricier rivals away in a couple of key areas, with sleek looks and week-long battery life. However, with a bespoke operating system it can’t load more than the preinstalled selection of basic apps, and its companion smartphone app is only available on Android at launch. Despite a few software glitches betraying its first-gen status, the OnePlus Watch is good value for the price, which is notably lower than Samsung and Apple competitors.

We might have a better opinion of the OnePlus Watch if we waited until six months after it launched. We gave OnePlus a few weeks and a couple of updates to fix a few glaring problems, because we like to review new tech at Stuff, not gadgets half-way to the retirement village. OnePlus added a few features, no doubt squashed some bugs. But the main one remains. The OnePlus watch cannot reliably track outdoors exercise thanks to dodgy GPS execution and fumbled handling of the data it does record, compounding the problem. The Huawei Watch GT2, or its cheaper sibling the Huawei GT2e, are better buys.

On the surface, the OnePlus Watch is a premium smartwatch in design and hardware at an affordable price. However, it’s severely let down by its frankly unfinished software.

Unfinished software; Unreliable tracking; No smaller size;

The frustrating thing about this watch is that it just feels unfinished. Sure, it looks pretty enough and battery life is great, but it's incredibly unreliable as a fitness tracker - so, at launch, not fit for purpose.

OnePlus has new phones on tap for next week's product launch, but YouTube channel Unbox Therapy has details about another device on the agenda—a smartwatch. Unbox Therapy tweeted the first full image of the device. It looks pretty similar to other smartwatches on the market, with a round watch face, at least two side buttons, and a rubber or silicone band. Tweet OnePlus responded to the image by inviting everyone to attend its March 23 event, where the smartwatch will launch alongside the OnePlus 9 flagship phones. (Stay tuned for our coverage.) On Wednesday, OnePlus CEO Pete Lau also teased details about the upcoming watch, which he says has been the most requested device from the company’s customers. “Our priority for devices that are part of the OnePlus ecosystem is to offer fashionable designs, provide seamless connectivity and deliver a best-in-class user experience. And the new OnePlus Watch is no exception,” he wrote in a forum post.  He stressed the product will arrive w...

OnePlus' first attempt at a smartwatch is designed to be affordable and useful for fitness tracking. Time will tell if it's hit the spot.
