Perfect watch but Should be listed as 11139-AZ2!

I bought AZ1, but The Black Watch arrived, particularly the model listed like 11139-AZ2. On the backside of the Blackwatch there is 11139-AZ1 engraved, so the items are listed wrong. I had to send the wrong model back, Because Amazon offerd no exchange, just refund. Update - Buy this watch from Amazon and you will get black one, buy this one from Warehouse Deals and You Will Receive White One (sticker AZ1 is Placed over the original sticker AZ2). Just received white That I wanted and it's perfect !!! Unfortunately This was the third I bought and had to return two Black watches before (once bought this one from Amazon and Second Time bought AZ2 listed like black from Warehouse Deals - It had AZ2 AZ1 sticker over the original sticker).
