Magical time reverser on chain
Hermione Granger and Harry Potter would certainly be delighted with such an enchanted amulet. A magic adult time reverser on a golden chain is a great thing and can perhaps conjure the wearer into the past or future... you just need to know the right spell to do it.
Moving amulet for witches and wizards
A time reverser hangs from the beautiful golden chain with toggle clasp and looks wonderful. In the centre is an hourglass set in a moving disc. The disc is connected in an axis with the inner ring and this with the outer ring. Each ring can be turned separately. The two outer rings have an inscription engraved on the rim:
"I mark the hours, every one, nor have I yet outrun the Sun.
My use and value, unto you, are gauged by what you have to do".
Hermione was given such a time reverser by Dumbledore in the Harry Potter films so that she could attend several courses and lessons at Hogwarts at the same time. Ours may come in handy too. You have to turn the hourglass once to be able to travel back in time an hour.
We didn't try it, as interfering with time is never entirely harmless. That's why the Ministry of Magic later destroyed Hermione's time reverser. Fortunately, we still have some of them in our secret storage.
