Display — 3000 vs 2200 nits
The watches have the same display size of 1.5 inches and identical resolution of 466 × 466 pixels. In everyday use, the screens look very similar — colors are vibrant, blacks are deep, and viewing angles are wide.
The key difference is brightness. The OPPO Watch X3 reaches 3000 nits, which is 36% more than the 2200 nits in the older model. In comparison, the display of the OPPO Watch X2 vs X3 is one of the more noticeable aspects — especially under bright sunlight while running, cycling, or walking around the city in summer.
The Watch X3 uses a next-generation LTPO OLED panel, while the Watch X2 uses LTPO AMOLED. Both support Always-On Display (AOD — continuous display of time and selected information on the screen), but the newer model should be slightly more energy-efficient due to the updated display technology.
Tip: If you primarily train indoors or in the evenings, the difference in screen brightness won’t be crucial for you. 2200 nits in the Watch X2 is still a very good result — more than in most competing smartwatches.
Design and materials — titanium vs steel
This is one of the biggest changes between generations. The OPPO Watch X3 has a case made entirely of aerospace-grade TC4 titanium, while the Watch X2 combines stainless steel with a titanium frame.
What does this mean in practice?
- Weight — The Watch X3 weighs 43 g without the strap (vs 49.7 g). The difference of 6.7 g is about 13% less. You will definitely feel this on your wrist, especially during sleep and training.
- Thickness — The newer model is 11.0 mm thick (vs 11.75 mm). The watch hides better under a shirt cuff and protrudes less on a slim wrist.
- Durability — Both have sapphire glass and MIL-STD-810H certification (military-grade durability standard). However, the Watch X3 adds IP69 (resistance to high-pressure hot water jets), which its predecessor lacks.
Both models have two buttons on the right side — the upper one serves as a rotating crown. The Watch X3 offers three color variants: Gravity Black, Global Star Orange, and Infinite Titanium.
Regardless of which model you choose, it’s worth investing in additional screen protection. At homescreen.pl you will find GrizzGlass HybridGlass hybrid glass and GrizzGlass CeramicFilm ceramic film for OPPO Watch X2 starting from 12.99 PLN.
Performance — Snapdragon W5 Gen 2 vs Gen 1
OPPO Watch X3 runs on the newer Snapdragon W5 Gen 2 with an ARM Cortex-A53 processor up to 1.7 GHz and Adreno 702 GPU. It is supported by the Qualcomm QCC5100 coprocessor. Watch X2 uses the Snapdragon W5 Gen 1 with the BES2800BP coprocessor.
In everyday use, the difference in smoothness is not dramatic — both smartwatches handle navigation through the menu, notifications, and apps efficiently. However, the newer chipset in Watch X3 should provide:
- Better energy efficiency — the same battery life with increased screen brightness and new sensors.
- Faster processing of health data — crucial for continuous monitoring of glucose, blood pressure, and ECG.
- Smoother animations — particularly noticeable when switching between watch faces and apps.
Both generations have 2 GB of RAM and 32 GB of internal storage, so in this respect, nothing changes. 32 GB is enough for offline maps, music, and several dozen apps.
Battery and charging — OPPO Watch X3 vs X2
The battery capacities are nearly identical — 646 mAh in the Watch X3 vs 648 mAh in the Watch X2. The declared usage times (according to the manufacturer) also match:
- Smart mode — up to 5 days
- Intensive usage — about 3 days
- Power saving mode — up to 16 days
So where is the difference? The Watch X3 achieves the same battery life despite a brighter screen and additional sensors, indicating better energy optimization of the new chipset and display.
The OPPO Watch X3 charges fully in about 75 minutes, while the Watch X2 takes about 60 minutes with the 10W VOOC charger. The newer model compensates for the longer charging time with a quick „emergency” charging feature — 10 minutes provides power for 24 hours. Useful when you discover a dead watch in the morning before your workout.
Note: Both models only charge with dedicated magnetic chargers — they do not support the Qi standard. Before purchasing, make sure you have the original charging accessory.
Health and Sensors — the Biggest Advantage of the Watch X3
This is an area where the OPPO Watch X3 clearly outpaces its predecessor. Both models offer:
- 24/7 heart rate monitoring
- Blood oxygen saturation measurement (SpO2)
- ECG (electrocardiogram)
- Blood pressure measurement
- Skin temperature measurement
- Sleep analysis with phases (light, deep, REM)
Watch X3 adds a blood glucose sensor — a feature that the Watch X2 lacks. The watch uses non-invasive optical technology for continuous monitoring of sugar levels. This is particularly useful for people with type 2 diabetes or prediabetes, but also for athletes tracking the impact of diet on training results.
It is worth noting that non-invasive glucose measurement from the wrist does not replace a professional glucometer. This technology is still developing and is more suited for observing trends rather than for precise medical measurements. Nevertheless, continuous glucose monitoring is a feature that most competitors in this price range do not offer — including Samsung Galaxy Watch and Huawei Watch GT.
In the showdown between OPPO Watch X2 vs X3, it is the sensors that make the biggest difference. The rest of the health features are identical.
Sports and Navigation
Both smartwatches support over 100 sports modes and GPS with dual-band L1 + L5 signal, ensuring precise route tracking in urban areas with tall buildings.
Watch X3 uses five satellite navigation systems (GPS, GLONASS, BeiDou, Galileo, QZSS), while Watch X2 uses four (GPS, GLONASS, Galileo, QZSS — without BeiDou). In practice, the additional system can improve positioning accuracy in difficult conditions — e.g., in dense forests or narrow streets of old towns.
Both models have eSIM with LTE support, allowing you to receive calls and messages without a phone. Useful when running or cycling, when you don’t want to take your smartphone with you.
In the context of sports, it’s worth mentioning the analysis of gait and posture while running — a feature available in both models. The watch monitors cadence, ground contact time, and vertical oscillations, providing runners with specific data to improve their technique.

Operating System — Wear OS vs ColorOS Watch
Here lies an interesting change and one of the key elements in the comparison of OPPO Watch X2 vs X3. Watch X2 runs on Wear OS 5.0 with the ColorOS Watch 7.0 overlay, which means access to apps from the Google Play Store — Google Maps, Spotify, Strava, and many others.
OPPO Watch X3 has transitioned to ColorOS Watch 16.0 as a standalone system. In China, Wear OS is not widely used, so OPPO opted for its own solution with better energy optimization. The question is: what system will the global version of Watch X3 receive?
If OPPO decides on Wear OS for the international version (as was done with Watch X2), the difference will be smaller. However, if the global version retains ColorOS Watch 16.0, access to applications will be limited to the OPPO ecosystem and selected partners.
Tip: If you care about the Google app ecosystem (maps, Spotify, Google Wallet), Watch X2 with Wear OS 5.0 is a safer choice — at least until we learn the details of the global launch of Watch X3.
Price and Availability — OPPO Watch X2 vs X3 in Poland
OPPO Watch X3 debuted in China at the following prices:
- Gravity Black — 2599 yuan (approx. 1400 PLN)
- Global Star Orange / Infinite Titanium — 2799 yuan (approx. 1510 PLN)
OPPO Watch X2 at launch cost around 1300–1500 PLN depending on the variant. It can currently be found at lower prices, making it an attractive option for those looking for a flagship OPPO smartwatch at a more affordable price.
The global premiere of the Watch X3 has not yet been officially confirmed, but the OPPO Watch X2 hit the international market (including Poland) a few months after its Chinese premiere. A similar scenario can be expected — it’s worth following the official OPPO website for updates.
OPPO Watch X3 Mini — a smaller version is coming
OPPO is also preparing a compact variant, the Watch X3 Mini, which is expected to be released in April 2026. Information about this model has appeared in several leaks, but the official specifications have not yet been revealed.
If the standard 47-millimeter size of the Watch X3 is too large for you — for example, you have a slim wrist or prefer smaller watches — it’s worth waiting for this model. The Watch X2 Mini turned out to be a popular alternative, and the Watch X3 Mini will likely follow the same path.
Current accessories for the smaller model are available — check out the GrizzGlass hybrid glass for OPPO Watch X2 Mini in our store.
Who is the OPPO Watch X3 for, and who is the Watch X2 for?
