Gresso’s iPhone 4 Time Machine
Gresso took the iPhone 4 to the next level with their unique add-on. What seems to be 6 clock faces on the back of your actual iPhone 4 is not an illusion but what Gresso has developed. The iPhone 4 Time Machine is just like any iPhone 4, except that it houses 6 identical Swiss mechanical watches. The way Gresso adds this to your iPhone is by actually replacing your glass iPhone back cover with their mineral glass with diamond coating and houses 6 mechanical watches. This add-on will be available sometime in 2011 and will cost around $6000 for this fancy upgrade. Let see how far you iPhone fanatics will go for this one.
