The iPhone 4 Time Machine from Gresso can tell the time in six different major cities around the world while also letting you chat with FaceTime and play Angry Birds.
The iPhone 4 Time Machine has six different Swiss Watches installed into its back plate that keep the time of Tokyo, Moscow, London, New York, Hong Kong and Paris. With all these watches installed, you might think that the iPhone 4 would put on a few centimeters. Not so, says Gresso, who claims that their addition of six watches increases the phone's width by only one millimeter thicker than a normal iPhone 4. If you really need to tell time in six different cities at once, the iPhone 4 Time Machine can be yours for a cool $6,000.
