I bought this watch less than a month ago and have taken great care of it. But despite all my efforts, I noticed today that the bangle scratches very easily. And I also noticed that the nob where you turn to adjust the time turned blue. I thought this is supposed to be tarnish free, but I guess not that one part. A little disappointed considering the amount paid for the watch. I would still recommend it, but just be aware that it is very easy to scratch this watch.
