Oppo has moved quickly. Less than a month after launching the Watch X3 in China, the company has unveiled the Watch X3 Mini — a more compact version aimed at users who found the 47mm Watch X3 simply too large for their wrist. The Mini doesn't cut corners on hardware to hit a smaller size, which is genuinely worth noting. It's a trimmed footprint, not a trimmed spec sheet.
Summary
- 1.32-inch AMOLED display: 466x466 resolution, 1,000-nit peak brightness, sapphire crystal glass — identical panel specs to many premium full-size smartwatches.
- 43.2 x 43.2 x 11.18mm case: Weighs 40.4g without a strap, available in gold, silver, and brown colorways.
- Snapdragon W5 Gen 1 chip with eSIM, Bluetooth 5.2, dual-band Wi-Fi, NFC, and multi-system GPS support.
- 354mAh battery: Rated for 2.5 days in full smart mode, one week in power saving mode.
- Priced from CNY 1,799 (~$263) without eSIM, and CNY 1,999 (~$293) with eSIM — China pre-orders open now, global availability unclear.
The Display and Build: Small Case, Zero Compromises on Glass
Fitting a sapphire crystal on a 1.32-inch AMOLED panel at this price is not a given — it's a deliberate material choice that pushes the Mini into genuine premium territory. The 466x466 resolution is sharp for a watch this size, and 1,000 nits of peak brightness is enough to stay readable in direct sunlight. The case dimensions — 43.2 x 43.2 x 11.18mm — sit meaningfully smaller than the Watch X3's 47mm footprint, and the 40.4g weight without a strap is light enough to disappear on the wrist during daily wear.
The colorways — gold, silver, and brown — are clearly positioned toward a fashion-conscious buyer. I suppose it's a reasonable assumption that a smaller, more ornate watch appeals to a different demographic, though the hardware underneath doesn't make any concessions on that front.
Sensors: The Full Stack
Nothing is missing here. The Watch X3 Mini carries an accelerometer, gyroscope, geomagnetic sensor, barometer, optical heart rate monitor, pulse oximeter, wrist temperature sensor, and ambient light sensor. That's the same sensor suite you'd expect on a significantly more expensive device. Over 100 sports modes and an AI sports coach round out the fitness credentials. The 5ATM and IP68 ratings cover swimming and general water exposure without issue.
Battery: The Honest Trade-Off
Here's the catch, and it's an obvious one given the smaller case. The 354mAh battery delivers 2.5 days in full smart mode — notably shorter than the Watch X3's multi-day endurance. Always-on display drops that to 1.5 days, and power saving mode stretches it to a week. For a watch this size, those numbers are reasonable rather than impressive. Users who prioritize battery life over form factor should stick with the larger model. Those who want something that actually fits a smaller wrist without compromise elsewhere will find the trade-off acceptable.
The OnePlus Watch 4 Mini Question
It's worth flagging — the OnePlus Watch 4 launched the same day as a rebranded Oppo Watch X3. If that pattern holds, a OnePlus Watch 4 Mini is a plausible product for global markets. Whether it materializes, and at what price, remains to be seen.
