About the OnePlus Watch 2

After a hiatus of several years, OnePlus has made a triumphant return to the smartwatch scene with the OnePlus Watch 2, a significant leap forward from its predecessor. A standout feature is its dual-engine chip architecture, comprising two chipsets collaborating seamlessly. This innovative design allows the smartwatch to switch between two operating systems, optimizing user experience while efficiently managing battery consumption. The more potent chipset engages only when necessary, ensuring the watch operates with impressive efficiency.

The OnePlus Watch 2 boasts an elegant aesthetic reminiscent of premium wristwatches and vintage cars, offered in two striking finishes—Black Stainless Steel and Silver Radiant Steel—accompanied by a 22mm interchangeable band. It meets rigorous durability standards, earning military-grade certification, as well as IP68 and 5ATM water-resistant ratings. This robust construction permits safe use in the shower or during freshwater swimming. The device features a main function button and an action button for quick access to workouts.

What distinguishes the OnePlus Watch 2 is its dual-chipset setup, allowing it to handle background tasks and more complex applications separately. This ensures a seamless user experience while effectively conserving battery life.

The OnePlus OHealth app provides a comprehensive overview of daily statistics and trends, offering customization options for watch faces, sync preferences, and notification settings. The smartwatch also enables on-screen responses to emails, control of music playback, interaction with Google Assistant, and even gaming experiences like Simon and Mini Soccer.

Tracking essential vitals, exhibiting a durable design, and running on the familiar WearOS 4 operating system, the OnePlus Watch 2 positions itself as a formidable competitor in the premium smartwatch market. Compatible with Android phones, our testing with the OnePlus 12 and Google Pixel 8 demonstrated seamless performance on both devices.

Flagship-level design

While the initial OnePlus Watch lacked refinement, the OnePlus Watch 2 emerges as a stylish timepiece that distinguishes itself from other smartwatches. Available in two appealing finishes—Radiant Steel and Black Steel—the stainless steel chassis exudes a flagship-tier look and feel. Notably, the digital crown and action button slightly protrude from the chassis, a design choice that not only enhances aesthetics but also serves to prevent inadvertent button presses.

However, the elegance of its appearance doesn’t compromise its durability. The OnePlus Watch 2 is well-equipped for rugged activities, boasting the same MIL-STD-810H durability rating often found on top-tier Garmin watches designed for outdoor sports. With an IP68 water resistance rating and the ability to withstand water pressure up to 50 meters, it is suitable for swimming. The display is crafted from sapphire crystal, a premium material also used in high-end watches like the Garmin Epix Pro and Apple Watch Ultra, which typically come with a significantly higher price tag.

Wear OS 4 software

Rather than persisting with its own RTOS, OnePlus has opted for Google’s Wear OS software, a choice seen in many leading Android smartwatches. While bearing similarities to the Samsung Galaxy Watch, the OnePlus Watch 2 retains certain proprietary apps and functions, resulting in a hybrid Wear OS 4 + RTOS experience driven by a dual set of adaptive chipsets.

The incorporation of Google apps significantly enhances the OnePlus Watch 2’s utility. From my wrist, I seamlessly accessed Google Calendar to check my meeting schedule, utilized Google Maps for transit directions to the meeting venue, and employed Google Pay for my subway fare. While there are additional third-party apps accessible through the Google Play Store, I found that the pre-installed ones effectively addressed the most common smartwatch requirements.

Impressive fitness tracking

Historically, I haven’t associated OnePlus with health-focused technology in the same way as Apple and Samsung, so my expectations for the fitness tracking capabilities of the OnePlus Watch 2 were initially modest. However, it pleasantly surprised me with robust support for numerous sports types and an intuitive activity-tracking app, simplifying the monitoring of daily movement, including step count. The sleep- and stress-tracking features offer additional wellness insights that can be conveniently accessed either from the wrist or through the companion OHealth app for Android.

In a comparative analysis, I pitted the heart rate sensor of the OnePlus Watch 2 against that of the Google Pixel Watch 2, known for its highly accurate sensor. Notably, the readings from the OnePlus Watch 2 closely matched those of the Google Pixel Watch 2. While I personally favor the fitness metrics delivered by Google’s Fitbit, the OnePlus Watch 2 also provides advanced insights for specific sports, such as running, encompassing vertical amplitude, ground contact time, stride length, cadence, pace, and VO2 max.

Great battery life and fast charging

OnePlus asserts that its second-generation smartwatch can endure up to two weeks in power saver mode and up to 100 hours in normal ‘smart’ mode. During my usage, involving occasional GPS activation for navigation or workout tracking using Google Maps, I found the need to recharge just under every three days. This still represents significantly longer stamina compared to most flagship smartwatches, such as the Galaxy Watch 6 and Google Pixel Watch 2, which typically require daily charging.

OnePlus: Never Settle

In terms of charging, the OnePlus Watch 2 impresses with its quick recharge capabilities. A mere 10 minutes of charging provides enough power for a full day, and a complete battery recharge takes just one hour. The proprietary charging base, equipped with a USB-C cable and OnePlus charging brick, facilitates fast charging. While utilizing the provided charging brick is recommended for optimal speed, the option to use a USB-C cable with the base offers a unique advantage, allowing for potentially fewer cables to carry while traveling. This sets the OnePlus Watch 2 apart from most smartwatches, which typically have an integrated charger with a fixed cable.
