Question about Huawei GT5 Pro

The Huawei GT5 Pro (46 mm) has a barometer that serves as an altimeter. It automatically measures altitude and atmospheric pressure at the current location and offers a calibration function for more accurate altitude readings. The altitude measurement is based on the barometer sensor, but this can occasionally be inaccurate and calibration in an open outdoor area is recommended. The watch displays barometric pressure and altitude and supports calibration via the barometer app or through outdoor training with a GPS signal. It therefore has an altimeter similar to other Huawei smartwatches.
