Only rotates in a plane

According to the description and picture, the two rings must rotate in each different levels around its own axis. However, this is possible in our piece in only one plane. The Time-Turner is otherwise very nice and the writing is clearly legible. The sand requires less than one second to complete by fall (since trickles nothing - it falls). The chain is long enough to be worn as a necklace, which, however, has little in common with the original, but where Harry and Hermione together Around the chain - which is definitely not possible.
Overall a nice piece of jewelry that is reminiscent of the original, not more.
