My wife ordered this watch about a year ago despite some of the reviews/concerns that it might actually be fake and that the band wouldn't hold up. A little more than 6 months in, this is exactly what happened. The band started to fray and change colors. Whatever material they are claiming it to be, is clearly untrue, at least for some of these.
Despite that, she loves the watch and ended up buying  a band directly from the company and it has already lasted longer than the first one.
It could be a fluke, and the band just happened to be bad, but you should probably keep that in mind when ordering this watch.
