Be careful when purchasing this item. I am not entirely sure about its authenticity and my suspicion is a direct result of the main picture for the item. I have never seen any michael kors watch that has the arrangement of the chronograph as shown. I have attached a second picture of what a rose gold michael kors chronograph (MK5128) should look like. Just be careful and make sure you are getting what you are paying for.
A brief search on amazon for MK5128 shows you this item as one of the matches. I am pretty sure the runway watch is NOT this.
Again, I may be wrong but I'm just giving forewarning. For the price offered here, you may as well go to the real MK store, heck even Macys, and assure you are getting authentic stuff. And a HUGE plus is that they will resize the watch for you at NO cost.
