The OnePlus Watch 3 brings refinements over its predecessor in several key areas. While it may look like the Watch 2, the new wearable features a larger 1.5-inch LTPO AMOLED display with a titanium bezel and sapphire glass cover. The panel sports 2,200 nits peak brightness which should make it easily legible outdoors.
The other new addition is the new crown element, which can be used to navigate the UI, unlike the one on the Watch 2, which was just there for looks. OnePlus Watch 3 comes in a single 46mm size and two color options – Emerald and Obsidian Titanium. The frame is still made from stainless steel just like last year’s Watch 2.
Watch 3 is 5ATM waterproof, IP68 water and dust resistant and features a MIL-STD-810H rating. Like last year’s model, this will be a Wi-Fi/Bluetooth-only wearable with no cellular connectivity option.
On the software side, OnePlus Watch 3 dual boots Google’s WearOS 5 with its extensive app ecosystem and a custom RTOS for less demanding tasks. You get the same Snapdragon W5 chipset which is joined by a custom BES 2800 co-processor and 32GB storage.
Watch 3 gets an 8-channel optical heart rate sensor, and a 16-channel blood oxygen sensor for health tracking. You also get the standard, sleep, stress and activity metrics as well as ECG measurements which are coming in Q2 2025. There’s a new 60-second Health Check-In which gives you a snapshot of your key health metrics. Activity tracking will benefit from the updated dual-frequency GPS receiver.
OnePlus fitted a 631mAh battery rated at up to 5 days of endurance with regular use and up to 3 days with intensive use. The power saver mode should extend the total use time to over 16 days.
OnePlus Watch 3 is priced at $329/€349/£319. Pre-orders are eligible for a $50/€50/£50 coupon and a free pair of OnePlus Buds 3/Pro 3. Watch 3 will start shipping on February 25.
