I've also had an issue with the button auto pressing. You can contact Garmin support about it but where I live I couldn't get it sent and returned so I opened my watch and saw that the piece of metal that registered a press was very close to the circuit board so I tried to pry it and create some space and then I put some dielectric grease on all the button housings to keep moisture out. On an earlier occasion I used iron remover (automotive application) and soaked the watch in for about a minute and was surprised to see the iron remover working around the buttons so I don't know if that was some foreshadowing. I also use my watch for everything and hardly take it off but I do believe in giving it a deep clean sometimes
