Huawei Watch GT 7 Pro - Full Scientific Review!
In a Nutshell
The Huawei Watch GT7 Pro delivers excellent heart rate tracking (99/100 score) across most exercises except weightlifting, where performance drops significantly. Sleep stage tracking shows improvement over previous generations but remains only average (64/100), with poor REM sleep detection. GPS performance appears good based on limited reliable data, though the watch's premium build and features don't justify the €429 price over more affordable Huawei alternatives with similar data quality.

Huawei announced the Huawei Watch GT7 and GT7 Pro with early access provided for testing. The focus is on the GT7 Pro series with the normal version to be discussed in a future video. Many testing results are expected to translate to the non-pro version due to mostly identical sensor sets. The video covers heart rate tracking during exercise, sleep stage tracking performance, and GPS tracking with some testing problems encountered.

Indoor cycling represents the easiest exercise to track due to minimal movement, lack of bumpiness, and minimal wrist tension. Testing against the Polar H10 ECG chest strap reference shows excellent performance. Points align closely to the blue reference line with a correlation of 0.99, approaching the maximum correlation of 1.00. Example sessions demonstrate the GT7 Pro (red) overlapping very well with the reference (blue-green) across all tested sessions. The watch calibrated initially but showed super good performance overall, matching the expected Huawei performance level.
Running shows a small code bug causing slight alignment issues in plots, requiring manual correction of correlation values based on good alignment. Overall performance remains very good with most points on or close to the blue line and correlation still at 0.99. Example plots reveal some moments of deviation, particularly in the beginning of runs. Performance is slightly less optimal for running compared to indoor cycling, though deviations are very minor.
