OnePlus is making it a lot easier to pick up a long-lasting Wear OS smartwatch right now. The OnePlus Watch 3 43mm, known for delivering some of the best battery life you’ll find on a Wear OS device, has dropped in price—making it a strong option for anyone who wants reliable fitness tracking, smart features, and fewer trips to the charger.
The OnePlus Watch 3 43mm originally launched in July 2025 for $299.99, but it’s currently selling for $249.99. That’s a $50 discount (about 17% off). The deal applies to both Black Steel and Silver Steel finishes, and it’s available through major retail channels as well as OnePlus directly.
What makes this smartwatch stand out is battery life. Many Wear OS watches struggle to last much more than a day, but the OnePlus Watch line is designed to go much longer. This 43mm model is rated for up to 60 hours (around 2.5 days) in smart mode. If you push it harder, OnePlus says you can expect up to 36 hours in heavy usage mode. Switch to power saver mode and it can stretch up to 7 days. Fast charging is also part of the package, with a 10-minute top-up delivering up to a full day of use.
The Watch 3 43mm features a 1.32-inch AMOLED display with a 466 x 466 resolution and a 60Hz refresh rate, all housed in a 43mm stainless steel case. Under the hood, it runs on the Snapdragon W5 Gen 1 paired with a BES2800BP low-power chip, along with 2GB of RAM and 32GB of storage for apps and files. It ships with Wear OS out of the box, so you get access to the familiar Wear OS experience and compatible apps.
On the health and fitness side, the OnePlus Watch 3 43mm covers essentials and then some. It can track heart rate (including variability), blood oxygen, and respiratory rate, while also offering sleep tracking, stress monitoring, fall detection, menstrual cycle tracking, and more. For workouts, it supports tracking for over 100 sports and activities, with auto-recognition for six of them. It also provides more detailed tracking for activities such as tennis, skiing, and swimming.
Durability and daily convenience are well covered too. The watch is rated 5ATM for water resistance and carries an IP68 rating for dust and water. It includes a microphone and speaker for Bluetooth calling, NFC for mobile payments, camera remote control, a barometer, Bluetooth 5.2, and dual-band Wi‑Fi.
Overall impressions of the OnePlus Watch 3 43mm tend to highlight its battery life, activity tracking, and broad smartphone compatibility as key strengths. The biggest potential concern is software support. OnePlus has promised three years of software upgrades and three years of quarterly security updates through 2027. However, the watch is still on Wear OS 5, and while OnePlus has said Wear OS 6 is planned for release this year, there hasn’t been much recent news on timing.
For shoppers who prioritize battery life in a Wear OS smartwatch—without giving up modern health tracking and everyday smart features—the OnePlus Watch 3 43mm at $249.99 is positioned as a compelling value.
