In this video I’m unboxing and fully reviewing the brand new OPPO Watch X3, which a lot of people are calling the king of Android smartwatches. I’ve been using it for some time, so this isn’t just a quick first look — I’m talking real comfort, real features, and what actually stands out day to day. Straight away, the design is a big win for me: aerospace-grade titanium alloy, sapphire crystal cover, and that 12-sided titanium bezel that looks smoother and more rounded in person. It’s also noticeably slimmer and lighter than the previous model, and at 43g with a soft strap, it genuinely sits on the wrist with no pressure. Health tracking is where OPPO really went all-in. You’re getting an 8-channel heart rate sensor, 16-channel blood oxygen sensor, ECG, vascular elasticity and vascular age estimates, plus sleep apnea risk detection — which I think is a seriously important feature. I also show the 60-second AI health check that gives me a quick overview across 14 indicators, and the hypertension risk assessment system that doesn’t just warn you, it actually suggests practical improvements based on multiple factors tracked over seven days. For fitness, there are 100+ sports modes, dual-frequency five-star GPS (my route tracking was very accurate), and an AI sports coach that adapts to your level. Add Fluid Cloud, dual-watch iPhone notification sync, pinch gestures, and battery that hits around 5 days in smart mode (up to 16 days long mode) with a 10-minute charge for a full day — and honestly, it’s one of the most complete Android smartwatch packages I’ve tested. Pricing starts at 2599 yuan, roughly £281 in the UK.
