An example of an interval training summary in the Suunto app and the explained problem. Total training was 16k. And I did 4x7min and 1x 4min interval training.

@Igor-Horvat no, they will not, the Suunto 9 and 9 baro are not produced, sold, or developed anymore.

@Pagan29 dans le menu de la montre, il doit y avoir un truc du style connectivité et à l’intérieur il faut virer la connexion à l’ancien téléphone.

@Pierre-L I would try and clean the sensor once more and put a few drops of isopropyl alcohol to displace any residual water and dry it in a warm place. Sometimes drops of water will trap and put pressure on the sensor giving erratic readings.

I would try that before I would say the sensor is bad.

@Rémi-Perrin-0
Are you wearing the watch long time before such activities or you just take it for running?
My idea : if you are just wearing the watch for activity, your body temperature will increase the watch, and thus the baro sensor, temperature, and if your sensor is dirty or… faulty, then higher temperature may give lower altitude.
Lots of if, but…
