Oppo Watch X3 goes official with titanium build and glucose tracking
Oppo has officially unveiled the Watch X3 alongside the Find N6, confirming a slimmer 47.4mm body, a 3,000 nit display and a new glucose monitoring feature. The watch builds directly on earlier teasers and leaks, bringing a titanium case, upgraded sensors and the same large 646mAh battery.
A true titanium unibody and refined design
One of the headline changes is what Oppo calls an “integral titanium” build. The Watch X3 uses a monoblock TC4 titanium chassis rather than a hybrid structure. In simple terms, this means the structural frame is carved from a single piece of titanium instead of combining metal with internal plastic or composite layers.
That is not a trivial shift. Titanium is harder to machine than aluminium or steel, so moving to a full unibody design suggests a more complex manufacturing process. The result is a watch that comes in 16% lighter and 6.4% thinner than its predecessor, despite using a tougher material.
The case measures 47.4mm across and 11.0mm thick, weighing 43g. The design also introduces a 12-sided bezel, giving the watch a slightly more angular look. Interestingly, the Gravity Black version keeps a fully circular appearance, setting it apart from the other finishes.
Durability remains a strong point. The watch carries IP68, IP69 and 5ATM ratings, along with MIL-STD-810H certification. Sapphire glass protects the display, which now reaches up to 3,000 nits under specific conditions such as outdoor workouts in bright sunlight.
Strap redesign and improved ergonomics
Oppo has also reworked the strap system. The new “bamboo joint” design uses segmented fluororubber with metal connectors, which allows for more flexibility and airflow. It is a small detail, but one that should improve comfort during longer wear.
The Watch X3 supports standard 22mm straps, which opens up more third party options. At the same time, the proprietary fit has changed, so older straps from previous Oppo or OnePlus models will not work with this generation.
Glucose monitoring and deeper health tracking
The most notable upgrade on the health side is continuous glucose monitoring. The watch can provide real time readings and flag unusual patterns. It also adds blood pressure tracking and hypertension risk assessment.
And while this sounds impressive, it is yet to be seen how this works in real life. At the moment, there is still no smartwatch that can reliably measure blood sugar. The situation is not very different for blood pressure measurements – these are estimates at best.
Those features sit alongside an already extensive sensor package. The Watch X3 includes ECG, vascular health analysis, heart rate tracking, SpO2, sleep monitoring with apnea detection and wrist temperature sensing.
Dual-chip system and sports features
Under the hood, Oppo continues with its dual-motor architecture. A low power BES2800 chip handles background tasks, while a Snapdragon W-series processor takes care of more demanding workloads. Oppo has confirmed this is not the newer high-end “Elite” variant, although the exact version remains unclear.
The watch includes 2GB of RAM and 32GB of storage, running ColorOS 16 in China with updated visuals and haptics powered by a new X-axis motor.
Fitness tracking remains comprehensive. There are over 100 sports modes, along with metrics such as VO2 Max, lactate threshold, recovery time and aerobic training effect. Dual-band GPS with support for L1 and L5 is included, alongside BeiDou, Galileo and GLONASS.
Battery life, charging and connectivity
Despite the slimmer build, battery capacity stays in the same range as before. The watch delivers up to 3 days under heavy use, around 5 days with typical usage and up to 16 days in power saving mode.
Charging is handled via magnetic pins, with a full charge taking around 75 minutes. A short 10 minute charge can provide roughly a day of use.
Connectivity includes Bluetooth 5.2, dual-band Wi-Fi and NFC. The Chinese version supports standalone eSIM, while global support remains unconfirmed. Oppo has historically limited eSIM availability outside China, so this is something to watch.
Pricing and availability
The Watch X3 is available in Global Star Orange, Gravity Black and Infinite Titanium. Pricing starts at CNY 2,600, with early bird offers lowering it to CNY 2,210. Higher end finishes come in at CNY 2,800, discounted to CNY 2,380 during pre-orders.
Sales in China begin on March 20, with international availability expected to follow.
