300-Year Old Pocket Watch's Mechanism Revealed with X-Rays...! (3pics)

Before you toss aside this hunk of corroded metal, look again....actually look again with the help of X-Rays.
This 17th century pocket watch was discovered off the coast of Scotland in the 1970's from a shipwreck dated from 1653. Since the, the hunk of ugly metal was kept in the National Museum of Scotland until historians used a technique called X-ray Computed Tomography (CT) to see what is hidden behind the corroded exterior... what they found was truly amazing.... check it out below: 

CT involves taking a series of slices through an object at different angles, and combining them using a computer to produce a three-dimensional reconstruction of the object's internal structure. Andrew Ramsey and his colleagues at the company X-Tek Systems in Tring, Hertfordshire, UK, had developed an improved CT technique using small yet high-voltage X-ray sources, which enabled them to obtain very high-resolution images, even when penetrating dense metal. Any parts made of steel, including the watch's single hand as well as the studs and pins that originally held the mechanism together, have corroded away. But most of the components are brass, and in excellent condition. "The results surpassed all of our expectations," says [Museum researcher Lore] Troalen. "We never thought that so much of the mechanism would have survived."
