Features - Both with GPS, only one with ambient light sensor and always-on mode

The Watch S Pro is a round smartwatch with a scaled bezel, the Watch 2 Pro follows the rectangular design founded by Apple. Beyond that, other differences are already noticeable in the design: While the Watch 2 Pro has only one button for operation, the Watch S Pro has two, but the lower one is permanently assigned to the training app. The straps are made of silicone on both, but only on the Watch 2 Pro realme sets an accent with the slogan "Dare to Leap". Translated, it means something like "Dare the jump"; a motivation to try something new.

Less obvious are the dissimilar materials: On the Watch S Pro the case and strap buckle are made of an aluminum alloy. On the Watch 2 Pro both are made of plastic, which realme conceals with a metallic look. On the scales, the aluminum alloy increases the weight to 44 g (~1.55 oz, without strap) compared to 40 g (~1.41 oz) for the Watch 2 Pro. The thickness of both is the same at about 13 mm (~0.5 in) despite the different dimensions due to the design.

The protection against water penetration is sufficient for the Watch S Pro 5 ATM is sufficient for swimming, while the Watch 2 Pro on the other hand, is only certified according to IP68. Thus, the smartwatch can be worn while exercising and washing hands, but should be taken off before showering or swimming.

Display

Only the Watch S Pro has an AMOLED display, which stands for better contrasts, among other things. However, the LCD of the Watch 2 Pro also surprised with a good contrast. The luminance of AMOLEDs cannot be directly compared with that of LEDs. Therefore, the 450 cd/m² of the Watch S Pro reported by the manufacturer should not be seen as a disadvantage compared to the 600 cd/m² of the Watch 2 Pro. However, the ambient light sensor, which only the Watch S Pro has to automatically adjust the brightness, is relevant in practice.

It also has a compass and a gyroscope. Both wearables support localization via two satellite navigation systems (dual-frequency GPS).


Software - Watch 2 Pro more flexible than Watch S Pro

The app portfolio is almost identical. In particular, both control the smartphone's music player and camera on demand. However, the latter depends on the smartphone in individual cases; and under certain circumstance not every manufacturer supports remote control of its smartphone camera. Both signal incoming calls and display messages from social networks, but not emojis. We find smaller differences in the alarm clock, for example: The Watch S Pro supports up to 10 alarms, the Watch 2 Pro a maximum of 5. Both signal the alarm via vibration, and the strength can be adjusted in three steps. On the Watch S Pro realme uses the geomagnetic sensor for a compass app.

In terms of the display of the apps and widgets, the Watch 2 Pro is more flexible: You can change the order of the apps and widgets via the realme Link app and hide those that are not needed. In addition, you can change the order of the apps and widgets on the Watch 2 Pro, you can choose between grid and list, while the Watch S Pro always presents the app selection as a grid.

Of course, both use the same realme Link app. In the test, we were able to pair both with the iPhone at the same time. However, the app manages the wearables and their data in separate areas. It therefore does not consolidate data such as training minutes.

Health and activity tracking - Watch 2 Pro with more sports, Watch S Pro with more details

Both regularly measure the heart rate, but the blood oxygen saturation is only measured manually. The PPG sensor estimated it comparatively reliably for both in the test. During the course of the day, they count the steps as well as the active training minutes and determine the calories burned in combination with the personal information about age, height and weight.

The app displays the daily statistics in roughly the same way, details of which can be found in both tests. As far as differences are concerned, the activity display of the Watch 2 Pro also shows the number of training minutes.

Training and analysis

When comparing the sports functions of the two fitness trackers, it initially seems as if the Watch 2 Pro is better suited for training than the Watch S Pro: Among other things, this is supported by a VO2max test, which concludes cardiovascular fitness from an analysis of performance and maximum oxygen uptake in combination with personal data (more on this in the Review of the Watch 2 Pro). In both sports trackers, the training app provides a choice of 15 sports, but you can only change the selection on the Watch 2 Pro where you can choose from 90 different sports.

The the Watch 2 Pro almost always builds the protocol for the many different sports in the same way. The Watch S Pro, which has a gyroscope, adds the number of swimming strokes and the resulting SWOLF value when swimming. In addition, only the Watch S Pro provides details about the heart rate during training, at least on the wrist. On the smartphone, the log for both turns out meager when compared with those of the Xiaomi Mi Watch or the Amazfit GTS 2e.

For swimmers, it should also count that the training app of the Watch S Pro offers swimming thanks to its better water protection (5ATM compared to IP68), the Watch 2 Pro does not, despite its overall larger selection of sports.

The following screens first show a running log of the Watch 2 Pro and then one of the Watch S Pro. While the output on the smartphone hardly differs, the recording on the Watch S Pro is more detailed than on the Watch 2 Pro.

GPS accuracy

Both wearables potentially increase their reliability with dual-frequency GPS in areas where high mountains or urban canyons affect the reception of satellite signals. In the test, both were often off track due to slight lurching, the Watch 2 Pro more than the Watch S Pro. Overall, however, the deviations remained within limits. In the end, the Watch S Pro determined a distance that was 100 meters (~109 yards) shorter than the actual distance run, while the Watch 2 Pro was about 150 meters (~164 yards) longer.

Battery and runtime

Both wearables target a runtime of up to 14 days. Because the Watch S Pro has a higher resolution of 454 x 454 px than the Watch 2 Pro (320 x 385 px) and the display is one of the strongest consumers of a smartwatch, realme has dimensioned the battery of the Watch S Pro at a larger 420 mAh compared to the Watch 2 Pro (390 mAh). If you activate the Watch S Pro always-on display, the battery runs out faster; however, we still managed an endurance of 5 days in the test even with a specifically high load on the resources.

Verdict

With a clear price difference of over 50 Euros (~$59), it is surprising that the Watch S Pro is not also clearly the better one. Besides the higher-quality aluminum casing, the always-on AMOLED display that independently adjusts its brightness thanks to the ambient light sensor is one of its advantages.

The Watch 2 Pro attempts to rise beyond the cheaper price with its flexibility in selecting and arranging apps and widgets, which can be quite practical for daily use.

Those who want to leave the realme Watch on in water should reach for the more expensive Watch S Pro due to the better case protection.

Athletes who also want to use the smartwatch for their workouts might get into a quandary: The Watch 2 Pro scores with VO2max test and considerably more sports profiles, the Watch S Pro offers more comprehensive analyses and has a gyro sensor that enables additional tracking functions, such as counting swimming strokes. However, water rats should find the decision easier anyway, since the Watch 2 Pro is only protected against water to a limited extent and does not even offer swimming as a sport.

In summary, the decision is between an inexpensive smartwatch with many sports profiles and user-friendly personalization, and a higher-quality smartwatch with a self-regulating always-on display and more detailed sports tracking.

Price and availability

The price difference is not small: At €74.99 (~$89), the RRP of the Watch 2 Pro is far below the RRP for the Watch S Pro (129.99/~$155). Some online retailers offer the Watch 2 Pro for about 5 Euros (~$6) less, but then add the savings to the shipping costs. Among others, you can get it from Amazon (DE) for €75.99 (~$90).  The daily price for the Watch S Pro fluctuated in the reviewed period. While it was still about 12 Euros (~$14) below the manufacturer's recommendation at the end of the test, it even climbed above the RRP at Amazon with 137.90 Euros (~$164) at the time of the comparison.
