Oppo Watch X3 Mini arrives with eSIM, sapphire glass and luxury styling
The Oppo Watch X3 Mini has gone official in China with a 1.32-inch OLED display, Snapdragon W5 Gen 1 chip and full eSIM support. All of this is packed into a smaller and lighter body than the standard Watch X3.
A smaller watch with premium materials
The new device launched as part of Oppo’s wider April event, which also introduced the Find X9 Ultra, Find X9s Pro, Pad 5 Pro, Pad 5 and Enco Clip 2. While the regular Watch X3 already covers the larger flagship space, the Mini version takes a slightly different route.
It comes with a circular 1.32-inch OLED display with 466 x 466 resolution and a 60Hz refresh rate. Oppo has protected the screen with sapphire crystal glass, which is still something you do not always see even on more expensive smartwatches. At 40.4 grams, the 5 ATM rated device is clearly designed to feel lighter on the wrist than the larger model.
The case keeps a polished look, with the standout option being a high-gloss gold finish made with 18K gold stainless steel. There are also mocha brown and starlight silver versions for those who want something less flashy. The watch uses standard 18mm quick-release straps, which should make replacements and customisation easy.
The styling also leans more toward jewellery than sport watch. Oppo seems to be pushing this as something that works both as a smartwatch and as a design accessory.
Proper smartwatch hardware, not just a fitness tracker
Under the hood, Oppo has used the Snapdragon W5 Gen 1 chipset paired with a BES2800BP co-processor. The watch includes 2GB of RAM and 32GB of storage, along with extra memory for RTOS operations.
It runs on ColorOS Watch 16 and supports eSIM, which means users can make calls and stay connected without carrying a phone nearby. Oppo is also highlighting support for direct calling from the wrist, WeChat replies and more than 100 apps, which helps position this closer to a full smartwatch than a simple health tracker.
There is also NFC support and the watch can function as a remote for your phone, including camera shutter control. So a few extras there.
Battery capacity is 345mAh, with Oppo claiming up to 2.5 days in smart mode and up to 7 days in extended mode. Watch VOOC fast charging is also included, with a 10-minute charge delivering up to 24 hours of use and a full charge taking around an hour.
Health tracking gets proper attention
Health and wellness features are clearly a big part of the pitch. Oppo includes an upgraded wrist temperature sensor, an 8-channel heart rate sensor and a 16-channel blood oxygen sensor.
There is also menstrual cycle tracking with exercise guidance, sleep monitoring and built-in GPS for outdoor activities. Running posture analysis and a professional swimming mode are included as well, so it is not just focused on passive tracking.
Pre-launch teasers also pointed to hypertension risk detection, although Oppo has not fully detailed how that works in the final launch specs. If that feature arrives with meaningful depth rather than just a simple alert, it could become one of the more interesting additions.
Pricing, availability
The mix here is interesting. It suggests Oppo wants the watch to sit somewhere between a fashion-focused wearable and a serious daily health companion.
Pricing starts at 1,799 yuan for the Bluetooth-only starlight silver version, which works out to around $265. The mocha brown and standard starlight silver eSIM versions cost 1,999 yuan, while the high-gloss gold version reaches 2,499 yuan, or roughly $370. No word yet on potential international availability.
