I got it from a thrift store. After changing the battery, it works, but there is an issue with the sensor - the Thermo, Meteo, Altimeter, and Compass functions don't work properly. I sent it to the Swatch Group for servicing, but they said they don't have the parts to repair it because this watch is an old model. Also, the middle button needs to be pressed hard to activate. Please check the photos and test video for details.
Thank you for your interest.
