OnePlus Watch 3 Now Comes in a Compact 43mm Size

OnePlus has officially added to its smartwatch series a smaller version of its flagship smartwatch the OnePlus Watch 3 (43mm). First launched in February 2025 with a 46.6mm case, the smartwatch is now joined by a smaller, more affordable 43mm version, appealing to those who want a streamlined wrist. It's not all about dimensions, however. The OnePlus Watch 3's latest variant comes with some changes that differentiate it from its older sibling, providing an excellent blend of fashion, smartness, and performance.

OnePlus Watch 3 Display Quality

The highlight of the change in the new model is, naturally, its dial size of 43mm compared to the 46.6mm version. The screen has also been resized accordingly. The Watch 3 (43mm) features a 1.32-inch AMOLED screen providing a crisp 466 x 466 resolution, 352ppi pixel density, and 2.5D curved glass protection. Although a little smaller than the 1.5-inch screen of the big model, it still shows rich colors and clear details, providing an experience of premium quality on the wrist.

Driven by Snapdragon W5 Gen 1 Chipset and Wear OS

Internally, the OnePlus Watch 3 (43mm) features the same robust Snapdragon W5 Gen 1 processor, ensuring seamless functionality and multitasking. It comes paired with 2GB of RAM and 32GB of internal storage, enabling users to download apps, save music, and so on. The presence of Google's Wear OS guarantees Play Store access, Google Wallet, Maps, and voice assistant support, while the low-power real-time activities are efficiently managed by RTOS integration. OnePlus has also added a BES2800BP MCU to offload normal tasks to enable longer battery life.

Stainless Steel Construction

Even with its smaller size, the OnePlus Watch 3 doesn't compromise on build quality. It has a top-of-the-line stainless steel case, so it looks and feels great while being strong enough to stand the test of time. For individuals worried about use outdoors or during workouts, the smartwatch has an IP68 rating, which means protection from dust and water. The Watch 3 (43mm) comes in two fashionable colors Silver Steel and Black Steel that work for both casual and formal occasions.

Rich Connectivity and Smart Features for Everyday Use

OnePlus Watch 3 (43mm) features a strong suite of connectivity features like Wi-Fi, Bluetooth, NFC, and GPS. Users are able to avail Bluetooth calling, conduct contactless transactions through Google Wallet, and discover more than 100+ customizable watch faces to make their experience more personalized. It also enables music and control for playback, remote shutter for the camera (for OxygenOS 15 or later devices), and even Short Video Control an exclusive feature for newer generation OnePlus smartphones.

Fitness Tracking for over 100 Sports and Health Tracking

In keeping with OnePlus' emphasis on fitness and health, the Watch 3 (43mm) features an extensive array of fitness tracking capabilities. The watch supports more than 100 sports modes, such as Skiing, Tennis, Badminton, Swimming, Cycling, Elliptical, Rope Skipping, and many more. Whether a serious athlete or a hobbyist fitness buff, this watch has you covered. It also provides 24/7 monitoring of heart rate, SpO2 monitoring, sleep analysis, snoring risk detection, blood oxygen levels when sleeping, and fall detection to provide a comprehensive health tracking experience.

Smaller Battery, Impressive Endurance

Another change in the new model is the battery size. The OnePlus Watch 3 (43mm) uses a 354mAh battery, which is roughly half of the 631mAh battery used in the 46mm variant. But with the optimized software and the dual-chip design, OnePlus boasts of a battery life of 60 hours on a single charge. The phone is also capable of fast charging and can provide up to 24 hours of use with a 10-minute charge, making it a great travel buddy for users.

Global Pricing and Availability

The OnePlus Watch 3 (43mm) has been launched at $299.99, which works out to approximately ₹25,800 in India. This makes it a bit of a budget offering over the 46mm variant that debuted at $349.99 (approx ₹30,100). The smartwatch is available for sale through the OnePlus website, and there are the Silver Steel or Black Steel variants to pick from.

With the OnePlus Watch 3 (43mm), OnePlus has made a thoughtful gesture towards giving users a form factor choice without having to sacrifice the features and performance the Watch 3 series is so famous for. From its sleek design and strong health monitoring to Wear OS capabilities and fast charging, this small smartwatch delivers a big punch. Whether you're upgrading from an older generation or are new to the OnePlus universe altogether, the new Watch 3 (43mm) is definitely worth considering particularly if you like aesthetics that are more streamlined and wrist-friendly.
