This is the third time I am sending this watch back to you. The problem with the watch is that the watch is starting to get slow or something. After about 1 hour the watch will show me the wrong time it could be 5-15 minute wrong, even when I´m wearing it when I´m outside the house. And please don´t leave any dust on the inside of the glass as you did the last time I send the watch to you. 

Thank you so much
Best regards
Hai Nguyen
