Very nice
This is very pretty and I do like how it looks. The coordinate numbers are a good size and  easy to read without being too large. There are marks on the back of the disc too, which I don't like. The marks match up to the numbers on the front, like the engraving affected the back of the disc. I do wish that wasn't there, luckily it isn't visible when you are wearing it. The heart also sits a bit higher in the circle than it shows in the pic.
