I bought this watch because i can no longer wear one on my wrist. I have to say i read the product reviews and was hoping that the people experiencing a lack of time keeping just got bad lemons, if that was the case: there are way to many bad lemons in this batch. Mine worked fine for the first week or so, after that it just started slowing down, now it does it more frequently. The watch went from being 10 min late every week to now being 20 min late every two days. needless to say, i will not recommend this product to a friend, i guess you get what you pay for.
