I also have a Suunto (semi) Smart watch. The model before the smart watches started up. IIt worked for about six months before thebuttons became erratic. Extremely bad after sales service. A later model was worn by James Bond or someone and suddenly that smart watch was available everywhere. I think the service may have improved. Mine still doesn't work ... must chase up someone to fix it a sixth time. At one time Suunto repairers claimed there were no replacement buttons available. Fffffing hell I would just buy a cheaper plastic version second hand and they can cannibalise it ...
