Long story short. Do not get your watches batteries changed at SM top floor watch shop near the cinema especially if its an expensive watch. The scam is he will "replace" the old batteries but actually will either put used batteries or put back the old one instead. It kept stopping after just 4 days. I brought my watch to another shop that looks more reputable and they showed me the battery was leaking and in fact this was the original battery of the watch for this brand of watches. If the battery was indeed replaced it would have been a a different brand. Apparently watch technicians are on commision basis so this kind of scam is common if you go to watch shops that do repairs. There's more to the story but I'm too pissed right now.
