I purchased this here, but it was a bit too big, so I only tried it on. It has RM and Sterling markings on the back. It's a matte, brushed silver, and although it's slim, it has a good thickness and the concho has a strong presence, making it easy to match with any fashion style. Since it's silver, it's somewhat adjustable, so you can widen or narrow it slightly to adjust the size and shape to your wrist. Inner circumference: 15.6cm Weight: 34g The grid lines in the fourth photo are 1cm each.
