OnePlus is expanding its wearable portfolio with the launch of the Watch 3 43mm, a compact smartwatch designed to offer flagship features in a smaller, lighter form. Scheduled for release on 8 July 2025, the Watch 3 43mm is part of a series of new devices aimed at meeting the needs of users who prefer a more discreet smartwatch without compromising on functionality. Building on the success of the larger OnePlus Watch 3, this new model brings a similar range of health, wellness, and design features to a wider audience.
**Compact Form Without Compromise**
Traditionally, smaller smartwatches have sacrificed features for a smaller size. However, OnePlus has taken a different approach with the Watch 3 43mm, delivering a full-featured experience in a compact design. The device boasts a 1.32-inch display housed in a stainless steel body, weighing just 37.8 grams. This makes it the most compact smartwatch from OnePlus to date, designed for comfort throughout the day, whether during workouts, sleep, or daily wear.
Despite its reduced size, the Watch 3 43mm does not compromise on performance or usability. It retains the core features of its larger counterpart, including comprehensive health tracking, long battery life, and a premium build. The goal is to provide a smartwatch that suits users with smaller wrists or those who prefer a more understated device, without sacrificing the functions expected from a modern wearable.
**Design: Blending Classic and Modern Aesthetics**
Continuing OnePlus’s minimalist design philosophy, the Watch 3 43mm merges the visual appeal of traditional watches with modern technology. The watch face is protected by a 2.5D micro-curved crystal, offering a seamless transition between materials and a smooth, tactile experience. With screen-printed 12-hour indices, the device pays homage to classic watch design while ensuring easy readability.
Available in Silver Steel, the Watch 3 43mm features a metallic texture that enhances its understated appearance. The overall aesthetic is one of refined simplicity, appealing to users who value both style and substance in their wearable devices.
**Advanced Mind and Body Wellness Features**
Health monitoring is a key focus for the Watch 3 43mm, with OnePlus emphasizing a holistic approach to physical and psychological well-being. The enhanced ‘Mind & Body Evaluation’ system stands out, providing users with a detailed understanding of their health status.
**Real-Time Fatigue and Stress Tracking**
An impressive feature is the real-time barometer that assesses the body’s fatigue levels every 30 minutes. This data offers insights into the user’s mental state, helping them identify stress or tiredness patterns. The watch also tracks daily stress patterns, providing a more comprehensive view of overall well-being.
**Guided Breathing and Personalised Prompts**
To support mental health, the Watch 3 43mm includes a one-minute guided breathing session with real-time feedback on relaxation techniques. Users receive daily and weekly summaries of their mind and body status, along with personalized prompts to reduce stress and encourage healthier habits.
**Comparison with the Larger OnePlus Watch 3**
Compared to the larger OnePlus Watch 3, the 43mm model retains many of the same appealing features in a size better suited for smaller wrists. The main differences lie in size and weight, with the 43mm model offering a more discreet and comfortable fit. Both devices share core health and wellness features, ensuring users do not have to compromise on functionality.
**Broader Product Launch**
The Watch 3 43mm is part of a coordinated release with four other OnePlus devices: the Nord 5, Nord CE 5, Buds 4, and Pad Lite. This launch showcases OnePlus’s commitment to offering a diverse range of devices to cater to various user preferences and needs.
**Conclusion**
The OnePlus Watch 3 43mm is positioned as a feature-rich smartwatch in a compact, lightweight design. It overcomes the limitations often associated with smaller wearables by providing advanced health and wellness tracking, a refined aesthetic, and a comfortable fit. By maintaining the core features of the larger Watch 3, OnePlus ensures users do not have to compromise between size and functionality.
For those seeking a smartwatch that balances style, comfort, and comprehensive health monitoring, the Watch 3 43mm is a standout choice. Its focus on physical and mental well-being, combined with a minimalist design, makes it a practical option for users who value both function and appearance.
