Description

Premium Design from Ultimate Titanium and Unmatched Comfort

The OnePlus Watch 4 is where high engineering meets elegance, featuring a body made entirely of premium titanium alloy with distinctive rivet details. Despite its exceptionally robust construction, it achieves an impressively slim profile at just 11mm and a weight that does not exceed 43g (without the strap). It is 13% lighter and 6% slimmer than its predecessor, offering such a light and comfortable feel on your wrist that you will forget you are wearing it, whether you are at a formal business meeting or working out.

Top Dual Processor Architecture Snapdragon W5 & BES2800

Power meets smart energy management through OnePlus's innovative Dual-Engine architecture. The smartwatch is equipped with the powerful flagship processor Snapdragon® W5, which works seamlessly with the advanced BES2800 chipset. This combination allows the device to intelligently switch between demanding processes and low-power functions. As a result, you enjoy an absolutely smooth and fast experience when navigating the menu and apps, without sacrificing your battery life.

Battery Life Up to 16 Days and Smart Features

Forget about the daily stress of charging. The OnePlus Watch 4 offers the best battery life in the full smartwatch category, leaving every competitor behind. In standard Smart Mode, the watch provides up to 5 days of full use with all features active. When you choose Power-Saver Mode, the battery life skyrockets to up to 16 days, while still maintaining Bluetooth connectivity, sleep tracking, and recording your daily workouts.

Google Gemini Digital Assistant Directly from Your Wrist

Keep your smartphone safely in your pocket and let the OnePlus Watch 4 handle everything. With the integration of the smart assistant Google Gemini, a simple voice command "Hey Google" is enough to quickly send messages, get answers to complex questions, or organize your tasks on the go. Google's artificial intelligence can recall important details and execute commands across various apps, bringing productivity and convenience directly to your watch screen.

Military-Grade Durability MIL-STD-810H for Every Adventure

Ready to face any challenge in any environment, the OnePlus Watch 4 is certified with the strict military standard MIL-STD-810H, having successfully passed 16 rigorous tests (extreme temperatures, drops, vibrations, and solar radiation). It features top-level IP68 and IP69 protection for complete resistance to dust and high-pressure water, as well as full resistance to corrosion from seawater. Additionally, the smart Wet-Hand Touch technology allows you to control the screen with absolute precision even with wet hands.

Complete Health and Wellness Overview in Just 60 Seconds

With the 60s Wellness Overview feature, just a one-minute check is enough to receive a complete and comprehensive report of your physical and mental condition. The watch collects and analyzes up to 9 different indicators in real time, as well as historical data. Through the OHealth app, you can monitor your heart health, blood oxygen levels (SpO2), wrist temperature, sleep quality, and stress levels, offering a clear picture of your body and mind.

Professional Tracking for Over 100 Sports Modes

For sports enthusiasts and serious athletes, the OnePlus Watch 4 features over 100 sports modes, with 11 of them supporting specialized professional-level algorithms (such as running, tennis, skiing, mountaineering, and swimming). The watch records detailed biomechanical data, such as racket swing speed, step cadence, and fat burning. Especially for running, the built-in Pace Assistant guides you in real time to help you maintain your target, while your lactate threshold is monitored to optimize your endurance.

    Truly excellent little watch, its battery is unbeatable with Bluetooth on almost every day for 9 hours and it lasted 5 days without charging and still had 15% left. If you have a OnePlus phone, they work perfectly together.
