"Tissot Touch" Touch screen failure
it all stems from the watch not actually being waterproof it's more water resistant than waterproof. The little indentations on the back that look like they are for a tool to unscrew it are actually holes i guess for the altimeter and meteo so it can sense pressure. Behind the back just behind the holes is a nylon gauze material and underneath this is a sensor slightly recessed and covered with some kind of waterproof substance. As far as i can see the problems lie here any water sweat or other foreign object than gets into this gauze will eventually will clog this gauze material which at first will affect the altimeter then the meteo. When the gauze has been clogged up severely i gets very dirty indeed which means when it gets wet it takes an age to dry out so if you wear it in the shower like i used to it will never dry out this causes the watch to malfunction quite severely. You can actually fix this problem yourself just get a very small flat screwdriver and lever the back off don't worry it's only a push fit and comes of easily you will see straight away a dirty damp smelly clogged up round piece of nylon gauze clean this up with a bit of WARM not boiling soapy water being careful not to disturb the pressure sensor and it's waterproof goo inside then dry it all and put it together
Hope this helps
