The Watch GT2 Pro has the same sensors as the Watch GT 2e, namely a heart rate sensor, a barometer, an altimeter, a gyroscope, an accelerometer as well as an integrated GPS. Overall, the performance offered by this gear is good.
GPS, first of all, proves accurate most of the time. Some deviations are to be noted, but they are quite rare and sufficiently spectacular to understand that there is an error. Sometimes it takes a very long time to calibrate, up to a minute. What frustrates when we want to start the session. Note that if you want to start the session without GPS, the Watch GT2 Pro will attempt to measure the distance traveled with the accelerometer and the gyroscope. An unconvincing method since we face differences of about 2 kilometers for 10 kilometers.
The heart rate monitor of this Watch GT2 Pro is relevant. Interpreted by the TrueSeen 4.0 algorithm, it ensures very relevant results on a smooth endurance output. Under these conditions, we note a margin of error of around 5% compared to the Polar H10 chest strap which we consider to be very reliable. This corresponds to a difference of approximately 10 beats per minute between the two measurements. During interval training, the results differ more. Thus, the margin of error increases to 15%, or 20 to 25 beats apart. The curve remains consistent.
Like many watches, the Watch GT 2e is able to track the user’s sleep. And like many other watches, it is extremely easy to trick it. For example, just lying in bed using your smartphone will make the Watch GT 2 think you’re still asleep.
To assess the performance of the Watch GT 2 Pro, we compared its results with those of the Polar H10 chest strap, which we consider to be very reliable when it comes to measurements. We measured the running by doing a series of laps on a 1.9 km circuit.
