Pretty much anything can be made unfathomably expensive by encrusting it with diamonds -- so when you start with an object that's already rather pricey, you're bound to start brushing up against "only for Russian billionaires" territory. Indeed, we'd argue that Ulysse Nardin's new Chairman Diamond Edition fits that bill nicely, coming in at $129,000 for a combination of 18-carat white gold and over 2,000 diamonds with ceramic trim. You might recall that the plain-vanilla Chairman is already an interesting phone, featuring 32GB of storage, a 3.2-inch touchscreen, Android, biometric scanner, and most notably, a watch-like self-winding mechanism around back that supplements the phone's battery power. Of course, when your phone runs into the six figures, we doubt that paying the electric bill to get this thing charged on a nightly basis will be much of an issue.
