OnePlus Watch 3 Review: The Most Stylish and Long-Lasting Wear OS Smartwatch Yet

Introduction & Unboxing

The OnePlus Watch 3 enters the scene with a polished evolution of its predecessor, the much-loved OnePlus Watch 2. Known for its bold asymmetrical design and stellar battery performance, the Watch 2 set the bar high. Now, OnePlus has refined that formula with slimmer bezels, a larger and brighter LTPO AMOLED display, and a bigger 610 mAh battery — all wrapped in a premium titanium and stainless steel body.
Unboxing reveals a familiar package: the watch itself, a USB-A to USB-C cable, and a four-pin magnetic charging cradle. While we still prefer wireless pucks that don’t require perfect alignment, the cradle does the job effectively.
At $350 / €300 / £300 (often available at a discount), the OnePlus Watch 3 comes in Obsidian Titanium and Emerald Titanium, both available in a single 46mm size with Bluetooth and Wi-Fi only (no eSIM).
Design & Build Quality

If style is a dealbreaker, the OnePlus Watch 3 delivers. With its brushed titanium bezel, sapphire crystal display, and MIL-STD-810H certification, it balances aesthetics with rugged durability. IP68 and 5ATM ratings further reinforce its resistance to water and dust.
At 49.7g (case-only), it’s on the heavier side — but it feels robust, not bulky. The 1.5-inch LTPO AMOLED display boasts 2200 nits of brightness, offering superior visibility even under harsh sunlight. The rotating crown now supports smooth scrolling, and the flush side button leads straight to workout modes.

Available straps include Black, Green, and Nordic Blue — sadly, no signature OnePlus Red strap.
Performance, Wear OS & Health Tracking

The dual-chip setup remains a highlight: Snapdragon W5 Gen 1 for full Wear OS and a BES2800 low-power processor for power-saving mode. You can toggle between Smart Mode and Power Saver Mode, the latter extending battery life by limiting features without gutting usability.
Navigating the UI is smooth: crown press for apps, side button for workouts, and intuitive swipe gestures. Over 100 sport modes are available (11 “professional” ones), with automatic detection for common activities. Dual-band GPS (L1+L5) delivers reliable accuracy on par with top-tier competitors.
Sleep tracking is improved, offering detailed insights into sleep stages, skin temperature, breathing rate, and blood oxygen levels — even snoring detection via smartphone.
Battery Life & Charging

Battery life is phenomenal — arguably the best on any Wear OS smartwatch. Expect up to 4 full days with AoD, daily workouts, and sleep tracking enabled. That’s double the endurance of rivals like the Galaxy Watch6 Classic. Charging is quick too, taking less than an hour to full.
Verdict

The OnePlus Watch 3 is a compelling all-rounder. With class-leading battery life, luxurious materials, and refined Wear OS integration, it checks almost every box. It's not the cheapest option, and its size may not suit everyone, but it offers unbeatable value if you love bold, premium design and long-lasting power.
If you're after a stylish, reliable, and durable smartwatch that doesn’t force daily charging, this might just be the best Wear OS watch of 2025.
