The accuracy of the Huawei Watch Ultimate's heart rate monitoring is a topic of mixed reviews. Some users and reviewers have found it to be generally accurate, especially for resting heart rate measurements. However, during intense activities like running, the accuracy can vary significantly.
One review noted that the watch's heart rate monitoring was "on point" during general use, but another detailed test revealed significant discrepancies when compared to a chest strap monitor. Specifically, the Huawei Watch Ultimate showed an average difference of 9.8% in heart rate readings compared to a MyZone MZ-Switch chest belt during nine runs totaling 96 km[4]. This suggests that while the watch might be reliable for casual monitoring, it may not be the best choice for precise heart rate tracking during intense workouts.
Additionally, the watch's ability to capture extreme peaks and valleys in heart rate during high-intensity interval training (HIIT) activities is limited, similar to other smartwatches like the Apple Watch[7]. For precise heart rate monitoring during such activities, using a third-party Bluetooth chest belt monitor is recommended.
Overall, the Huawei Watch Ultimate provides a range of health-tracking features, including continuous heart rate monitoring, ECG, and SpO2 tracking, which are generally well-regarded. However, its heart rate accuracy during intense exercise is not as reliable as some might prefer[9].
