OnePlus Watch 4, 16 Days of Battery Life, Health & Fitness Tracking

Appearance

Titanium. Sharper every glance.

Where engineering meets elegance — an all-Titanium build with distinctive rivet detailing.

Titanium. Lighter every step.

At just 43 g and 11mm, OnePlus Watch 4 is 13% lighter and 6% thinner than its predecessor — full titanium alloy comfort you'll forget you're wearing.

Titanium. Stronger every adventure

Stronger every challenge. Built to MIL-STD-810H military-grade standards with wet-hand touch control and full seawater corrosion resistance — OnePlus Watch 4 handles every environment without hesitation.

Intelligent

Smarter every answer.

Synergy. Seamless every experience

Power meets endurance, smarter. Our Dual-Engine Architecture teams the Snapdragon W5 with the cutting-edge BES2800. Together, they deliver elite performance for your active life and significantly extended battery life, so you can do more, for longer.

Get Help from Google Gemini on the Go

Get help from Gemini on OnePlus Watch 4. Just say “Hey Google” to send a quick message or complete tasks on the go, and keep your phone tucked away. Gemini can handle tasks across apps, answer questions, and recall important details, so you can get more done from your wrist.

Professional sports modes

Performance. Elevated every metric.

Extensive dedicated modes — from professional running to court-ready tennis — delivering granular data on pace, posture and stroke for serious athletes. Whether you're chasing a personal best or refining your form, 100+ sports modes deliver the granular biomechanical data serious athletes depend on — pace, posture, stroke, fat burn and beyond.

Professional Running

Pace. Guided every stride.

A built-in pace assistant tracks your gap to target in real time, guiding form and effort so you can focus on running — not constantly checking your wrist.
