I ordered the black version, and I got this because I like Calvin Klein gear...and I like magnets. The magnetic closure isn't as convenient as I'd expected because it takes some work to line up the pieces to slide them together, but it holds together great.
It's very nice looking, although I was disappointed that some of the metal pieces were scratched upon arrival. It also seemed like a returned item, but it was sent as "new." I say that because the box wasn't sealed, and the bracelet wasn't placed around the internal "pillow" like they normally are.
Mine came with no instructions, but there are two magnetic pieces that you can remove (one or both of them) to make the diameter smaller.
As I write this (and when I ordered it), this is priced at $120. Yikes. I was expecting really good quality for a leather bracelet at that price. The leather is fantastic, but the metal pieces being scratched didn't give me that "yeah, it's worth it" feeling. It fits okay, but it's not all that adjustable and is still a bit big even after removing the two adjustment links. To me, this is more like a $30 bracelet. If you love the brand, it might be worth it to you...but I really like the brand, and I don't think that you should pay anywhere near $120 for it.
