OnePlus Watch 3 (43mm) will have a 1.32-inch display, weigh as much as a Pixel Watch

Ahead of its launch on July 8, OnePlus is showing off the smaller 43mm version of its Watch 3 and confirming a couple of key specs.

In a press release, OnePlus says that Watch 3 (43mm) will feature a 1.32-inch display underneath a crystal cover. The watch will have a stainless steel build in “Black Steel” and “Silver Steel” colorways.

Perhaps one of the best changes is in the weight. The OnePlus Watch 3 (43mm) will weigh in at 1.3oz, or roughly 37g. That’s the same weight as the 45mm version of Pixel Watch 3, or just 1g heavier than the original Pixel Watch (which was also made from stainless steel).

OnePlus further says that users can expect an upgrade “Mind & Body Evaluation” feature here, as well as “a real-time barometer, which can evaluate your body’s level of fatigue every 30 minutes.”

OnePlus Watch 3 (43mm) launches in the US and Canada on July 8.

The company’s full press release follows:

OnePlus Watch 3 43mm: Elevating Design, Mind and Body Wellness

New York, New York, June 26, 2025 – Global technology brand OnePlus is launching two new IoT devices on July 8, 2025, including a new, compact smartwatch, the OnePlus Watch 3 43mm. Following the success of the OnePlus Watch 3 46mm earlier this year, the OnePlus Watch 3 43mm integrates flagship features into a smaller design, setting new standards for the smartwatch experience on smaller wrists. A key distinguishing feature of the OnePlus Watch 3 43mm is the “Mind & Body Evaluation” tracking, offering comprehensive health monitoring, making it easier than ever to track wellbeing and cultivate healthy lifestyle habits.

Uncompromised Performance for Smaller Wrists

Traditionally, smaller form factor smartwatches meant significant compromises in functionality. True to OnePlus’ “Never Settle” philosophy, the OnePlus Watch 3 43mm breaks this limitation by delivering a fully featured smartwatch experience in a sleek, lightweight design.

Featuring a 1.32-inch display within a stainless-steel body weighing just 1.3 ounces, the OnePlus Watch 3 43mm is the most compact smartwatch the brand has ever created. Its refined form factor fits naturally on the wrist, ensuring all-day comfort – even during workouts or sleep.

Elegant and Durable Design

The OnePlus Watch 3 43mm features a minimalist design philosophy, blending the elegance of classic watches with the allure of cutting-edge technology.

Its watch crystal boasts a 2.5D micro-curved design, ensuring a seamless transition between different materials and creating an elegantly unified aesthetic, while providing a comfortable and smooth touch. The watch crystal is complemented by a screen-printed 12-hour indices, ensuring a precise time-reading experience, echoing the classic charm of traditional timepieces.

The OnePlus Watch 3 43mm will be available in Black Steel and Silver Steel, featuring a distinctive metallic texture.

Elevated Mind and Body Features for Improved Mental Wellbeing

Health monitoring is a significant feature in smartwatches, enabling users to track health data and support a healthy lifestyle. The OnePlus Watch 3 43mm provides a comprehensive focus on health, encompassing not only physical but also psychological wellbeing via upgraded OnePlus “Mind & Body Evaluation.”

The OnePlus Watch 3 43mm includes a real-time barometer, which can evaluate your body’s level of fatigue every 30 minutes, and by extension what that reflects about your mental state. It also tracks your daily stress patterns and helps you identify key factors affecting them.

To support stress relief, users can initiate a one-minute guided breathing session, with real-time feedback showing how the body responds to the exercise. In addition, the watch provides daily and weekly trends on your mind and body status, along with personalized prompts to help reduce stress and improve overall wellbeing.
