Tiffany Atlas Dome Chronograph Thank you for viewing. Purchased at Tiffany, and it is definitely authentic. Because I used it normally, I replaced the original leather band with a crocodile band when it deteriorated. The band's metal fittings haven't been changed, so they are genuine! There are some minor scratches and dirt that can be removed, but nothing noticeable, and it's in a clean condition. The battery is currently dead, so it needs to be replaced. I have never had it overhauled, so I recommend it. It is, after all, a used item, so please refrain from purchasing if you are sensitive to such things. Although it is already discontinued, the current model with the same design costs over 600,000 yen! I am reluctantly selling it... Feel free to comment!
