A mi me pasón con un pro 3 ultra después de salir de la piscina y haciendo esto se restableció
(sacado del forum de Mobvoi

1. After wearing the watch again, do off-wrist calibration again (setting-> personalization -> calibration, last item)
2. If off-wrist calibration cannot be performed, restart the watch before performing calibration
3. If restarting off-wrist calibration also does not work, and then reset the watch
Long press the two buttons for 10 seconds, let go when the TicWatch logo appears on the watch, then use the function button (bottom right) to select Enter Ship Mode, and then press the Power button to confirm. At this time, the watch will turn off, and then press and hold the Power button to turn it on to see if it returns to normal.
