I bought this watch in September 2013 and I was very happy when I received it. It came in a nice box and its size fits my wrist perfectly. It looks really good in person! However, when it comes to data counting, I've come into this little problem. When a month counts 30 days it won't count 30 days, too, remaining one day behind. So the data has to be set manually. Not a problem this aspect. But after I set it manually, the data won't turn into the next one the following day. Where am I doing wrong? Please, can you explain me how to set the data? Maybe I am not switching in the right direction (up to down). Thank you very much!
