Vertu has introduced its latest handset, the Signature Pure Black which is specially handcrafted thanks to the PVD (Physical Vapour Deposition) technique that is currently being used in watches. This will require vaporizing a block of Titanium Carbide at extremely high temperatures using a plasma beam in a vacuum chamber, where the resulting PVD coating makes sure you are the recipient of an extremely rugged surface which is nigh impossible to scratch unless Wolverine comes along. It retails for a whopping $14,835, which is pretty much in line with the rest of the Vertu handsets.
