The TicWatch Pro 3 Ultra GPS has a host of sensors. Heart rate monitor, oximeter, GPS, gyroscope, accelerometer and barometer are therefore included.
Let’s start with the GPS, whose presence is honored in the name of the model. This one offers faithful results. The plots are realistic and allow consistent tracking of its output. Compared to a smartphone, this solution will be a little more precise.
On the heart rate monitor side, the results are also convincing. During a gentle ride, without much variation in heart rate, the curves offered are very close to that of the Polar H10 chest strap which serves as our reference. The difference between the two is less than 1%, and is therefore around a beat. Even during an interval session, where the heart rate variations are numerous and significant, the watch manages to follow without too much problem. Only the very rapid variations at the very beginning of the session are not always identified. After the first five minutes, the curves – a little less precise than those of a chest strap – remain realistic. The differences in heart rate remain around 1 or 2%, ie three or four beats maximum. Nothing to say on that side.
The TicWatch Pro 3 Ultra GPS also offers sleep and blood oxygen saturation tracking. So many metrics that we are not yet able to assess, due to the lack of a dedicated test protocol. We must therefore content ourselves with telling you that their data seem consistent with our observations.
