Oppo Watch X3 clears certification with Android, LTE and eSIM support
A new Oppo smartwatch with model number OWW261 has received network access certification in China. This is widely expected to be the Oppo Watch X3, and it may debut alongside the Find N6 foldable.
Certification activity confirms imminent release
The certification was published by China’s Ministry of Industry and Information Technology. It confirms the OWW261 model name and references the device as a TD-LTE wireless terminal with Android OS.
The filing also mentions eSIM support, voice functionality and a single-antenna LTE design. The certificate was issued to Oppo Guangdong Mobile Communication Co., Ltd., with validity stretching through late 2027.
The location of manufacture is Dongguan City in Guangdong Province. Which ties in with Oppo’s typical smartwatch supply chain. This adds weight to speculation that the Watch X3 is entering final launch preparations.
Tipster @experiencemore claims the Watch X3 will switch from Oppo’s proprietary charging connector to USB-C. If accurate, this would be a welcome change, streamlining charging with a standard cable and removing the need for specialized hardware. Most Android phone owners already have USB-C cables on hand, which would simplify everyday use.
What the previous model tells us
The Oppo Watch X2 launched in China in February 2025. It packs a 1.5‑inch AMOLED display pushing up to 2,200 nits of brightness, a sapphire crystal mirror for protection and a titanium alloy bezel. The device stands out with a semi‑conical rotating crown and a secondary function button that also works as an ECG sensor.
Health tracking includes an 8‑channel heart rate sensor, a 16‑channel SpO2 sensor, wrist temperature tracking. Also available is a quick 60‑second physical exam feature that gathers key vitals. On the more novel front, Oppo debuted long‑term blood pressure monitoring in the X2, requiring consistent wear in full smart mode to activate risk alerts.
Battery life is good for up to 5 days in full smart mode and up to 16 days in light mode. This is supported by VOOC fast charging. Dual‑frequency GPS was included for more accurate outdoor tracking.
Watch X3 should build on this mix of robust health sensors, long endurance and smart features while adding USB‑C charging and full eSIM with LTE voice support. If it gets some healthy upgrades, it could shape up as a more self‑contained and practical watch for users who want network independence without carrying a phone.
Launch timing and expectations
Multiple sources suggest the Watch X3 will debut alongside the Oppo Find N6 foldable. With both devices likely targeting high-end users, a joint release makes sense. No exact launch date has been confirmed yet, but Oppo’s recent certification history points to an announcement within weeks. Most likely at the start of 2026.
