A new leak from tipster TECH INFO on X suggests the Oppo Watch X3 will feature a titanium body and a 632mAh battery. The information surfaced on social media, detailing a March 17, 2026, China launch, standalone eSIM support via an eUICC chip, and a smaller Oppo Watch X3 Mini variant.
The Oppo Watch X3 Leaked Specs
Oppo officially teased a new smartwatch earlier this March, but the real details are already spilling out online. This drop isn’t just a blind guess. It paints a clear picture of a wearable designed to fix the minor annoyances of the previous generation.
- Build & Display: The design sticks to a circular dial, complete with a side-mounted rotating crown for navigation. The big news? The chassis is being upgraded to titanium.
- Internals: You are looking at 2GB of RAM and 32GB of internal storage.
- Power: A massive 632mAh battery backed by 10W charging.
- Connectivity: True independence. The watch includes an independent eUICC chip for eSIM support. You can make calls and pull data without a smartphone in your pocket.
- The Sibling: A smaller Oppo Watch X3 Mini is officially in the works.
- Global Release Strategy: A OnePlus-branded watch carrying the model number OPWWE261 has also been spotted. History tells us this hardware will hit global markets eventually as the OnePlus Watch 4.
- Colorways: You get Gravity Black, Infinite Titanium, and Cosmic Orange options.
You have to look at the predecessor to see why this matters. The February 2025 Watch X2 shipped with a heavy stainless steel frame and a 500mAh battery. Shifting to titanium cuts the bulk while taking a beating. Bumping the battery capacity by over 130mAh is a massive engineering feat for a wrist wearable. That 32GB of storage remains identical to the last generation, but honestly, that is plenty of space for offline Spotify playlists.
Oppo already teased its upcoming flagship watch in early March. The March 17 launch date in China aligns perfectly with the brand’s usual spring release cycle. Also, the cross-pollination with OnePlus is standard operating procedure for BBK Electronics. We saw the exact same shared-hardware strategy with the previous generation.
I honestly think this is the battery upgrade we have been begging for. The smartwatch market is entirely stagnant right now. Companies keep giving us new software gimmicks that drain our batteries faster. A 632mAh cell actually changes how you interact with the device. You stop nursing it on a charger every single night.
The titanium shell on the standard Oppo Watch X3 is great, but the Oppo Watch X3 Mini is the actual hero of this leak. I despise the trend of strapping huge, heavy 46mm hockey pucks to our wrists. People with smaller wrists have been completely ignored by the “Pro” smartwatch sector for years. Releasing a Mini variant proves someone in the design lab is finally paying attention to basic human anatomy.
The physical rotating crown is another detail I am thrilled to see confirmed. Relying entirely on a tiny touchscreen with sweaty fingers is a miserable user experience. A physical crown gives you precise scrolling.
I am highly skeptical about the 10W charging speed, though. When you cram a battery this big into a watch, 10W is going to feel painfully slow when you need a quick 15-minute top-up before hitting the gym. But if the overall battery life pushes comfortably past the two-day mark, I can forgive a slower charge time.
Should you wait for this launch? If you are rocking an older Wear OS device and suffer from daily battery anxiety, absolutely. The leap to titanium alone makes it worth keeping your credit card in your wallet right now. The inclusion of the eSIM means runners can finally leave their heavy phones at home without dropping off the grid.
Keep in mind, if you live outside of China, you will probably end up buying this exact same hardware disguised under the OnePlus Watch 4 moniker later this year. But no matter the branding, the core hardware looks fantastic. Get your wrists ready for the Oppo Watch X3.
