Thanks for the responses. It wasn’t running very well when I purchased it so I sent it to be serviced and they did a full cleaning and servicing plus they replaced the crystal which is why it looks so clean.
I tried to remove the back case with the proper tool and it’s on so tight, I didn’t want to risk scratching it so I thought there might be another way to determine if it is pre-moon, but it seems like the consensus here is that it is pre-moon?
And yes, this is a photo box that I used to take the picture, I have an eBay store so I considered selling it but this one might be for my collection
