I Purchased this watch from a online store. This is the worst watch I have ever purchased, I bought this watch just because of its look. It has very stylish look which suits over me but the main demerit of this watch it’s battery backup. I’m a very sporty person, so whenever I have any sweats over my arms, the watch stops working properly. I have make it dry to run it again. I have complaint regarding this in their customer service forum, but they told me the watch works and they will not repair or returned the watch. They are fraud never buy this watch. There service is too bad.
