The diver gave his find to the National Museum of Scotland. The 17th century pocket watch reminds some crusty old rock. Conventional X-rays did not say much about the watch. But now the historians from the museum used the latest technique known as X-ray computed tomography (CT). This technique allowed the researchers to drop a glance inside the rusty shell. They were amazed to find out that the pocket watch’s 300-year-old mechanism is miraculously preserved inside its corroded body.
The pocket watch and its three-dimensional reconstruction are exhibited in the Treasured exhibition of the National Museum of Scotland till 2011.
