It has a spring hinge, which probably needs replacing by a jeweller, as it has become a bit loose... This bracelet has to have a spring hinge, otherwise it is unlikely you would get it on your wrist, as it is so solid, that it would not bend at all. It measures 6.75cm across. And 5cm from top to bottom.
I would say it is a ladies size, as I wore it and my wrists are not large. It was bought for me quite a few years ago.
