A Compact Powerhouse from OnePlus
On July 8, 2025, OnePlus will unveil the Watch 3 43mm, a smaller, lighter version of its flagship smartwatch, at the OnePlus Summer Launch Event. Designed for users with smaller wrists, this 37.8-gram wearable combines a sleek stainless steel chassis, a 1.32-inch AMOLED display, and advanced health monitoring, including the innovative Mind & Body Evaluation feature. Launched alongside the Nord 5, Nord CE 5, Buds 4, and Pad Lite, the Watch 3 43mm strengthens OnePlus’s ecosystem with seamless connectivity and premium functionality. This article explores its design, features, pricing, and role in OnePlus’s wearable strategy.
Design: Compact Elegance Meets Durability
- Build and Weight: The Watch 3 43mm features a stainless steel case weighing just 37.8 grams, making it OnePlus’s most compact smartwatch, ideal for all-day wear, including during sleep or exercise.
- Display: A 1.32-inch AMOLED with 466×466 resolution, protected by 2.5D micro-curved glass for a seamless, elegant look. Screen-printed 12-hour indices add an analog aesthetic, enhancing readability.
- Color and Style: Available in Silver Steel, with a refined metallic finish inspired by classic watches, balancing modern tech and timeless design.
- Durability: IP68 and 5 ATM water resistance, plus MIL-STD-810H certification, ensure resilience against water, dust, and extreme conditions.
The compact design caters to users seeking comfort without sacrificing premium build quality, making it versatile for work, workouts, or casual settings.
Mind & Body Evaluation: Holistic Health Tracking
The standout feature of the OnePlus Watch 3 43mm is its Mind & Body Evaluation, which monitors both physical and mental well-being:
- Real-Time Monitoring: A barometer assesses physical fatigue every 30 minutes, analyzing its impact on mental health. It tracks stress, heart rate variability (HRV), resting heart rate, and activity intensity to provide daily and weekly reports.
- Stress Management: The watch detects stress triggers and offers one-minute guided breathing exercises with real-time physiological feedback to promote relaxation.
- Emoji Feedback: An emoji on the watch face dynamically reflects your mental and physical state, making health insights intuitive and engaging.
Additional health features include:
- Sleep Tracking: Detailed analysis of sleep cycles, SpO2, and snoring risk, with long-term data to identify trends.
- Fitness Tracking: Supports over 100 sports modes, including 11 professional modes (e.g., running, swimming, tennis), with dual-frequency GPS for precise tracking.
- Health Sensors: Includes optical heart rate, SpO2, temperature, accelerometer, gyroscope, and geomagnetic sensors.
Note: ECG and 60-second Health Check features, available in some regions, are not active in Italy due to regulatory restrictions.
Performance and Battery Life
- Chipset: Powered by Qualcomm Snapdragon W5 Gen 1 and BES2800 MCU dual-chip architecture, ensuring efficient performance and power management.
- Software: Runs Wear OS 5, offering seamless integration with Google Play apps like Spotify, Strava, and Google Maps, plus customizable watch faces and widgets.
- Memory: 2GB RAM and 32GB storage for smooth operation and app storage.
- Battery: A 345mAh battery delivers up to 72 hours of use (compared to 100 hours for the 47mm model’s 631mAh). Fast charging provides a day’s use in 10 minutes.
The dual-OS approach (Wear OS for smart features, RTOS for low-power tasks) makes it more efficient than pure Wear OS smartwatches.
Ecosystem Integration
The Watch 3 43mm integrates with OnePlus’s ecosystem, enhancing connectivity with devices like the Nord 5 and Buds 4. Features include remote camera control, short video navigation, and seamless app syncing without resetting when paired with a new phone.
Pricing and Availability
- Launch Date: Set for July 8, 2025, at 10:30 AM IST, during the OnePlus Summer Launch Event, streamed live on YouTube.
- Price: While exact pricing is unconfirmed, it’s expected to be slightly lower than the standard Watch 3’s €349 (~$370), likely around €299–€329 (~$315–$350), based on its compact size and reduced battery capacity.
- Promotions: Launch offers may include bundles with Buds 4 or Nord Buds 3 Pro, similar to the standard Watch 3’s deals (e.g., €50 off or free accessories until April 30, 2025). A 10% student discount is also available with email verification.
Fan and Industry Reactions
Social Media Sentiment
Fans are excited about the compact design, praising its suitability for smaller wrists. Users noted its Pixel Watch-like weight and highlighted its health features, though some await global pricing details.
Industry Insights
The Watch 3 43mm has been lauded for its balance of style and functionality, with the Mind & Body Evaluation feature seen as a game-changer for wellness-focused users.

The Bigger Picture: OnePlus’s Wearable Strategy

It builds on the standard Watch 3’s success, which was praised as the best non-Google Wear OS smartwatch, offering up to 100 hours of battery life and premium materials like titanium and sapphire. With over 100 sports modes, advanced health tracking, and ecosystem integration, the 43mm model targets a broader audience, from fitness enthusiasts to those prioritizing mental wellness. Its launch alongside other devices strengthens OnePlus’s cohesive tech ecosystem.
