Diamonds, platinum, fancy tourbillons, chronographs, and perpetual calendars are only a few of the features watchmakers use to create the world’s rarest and most expensive timepieces. Bloomberg BusinessWeek asked the world's most prestigious luxury watch manufacturers to name their priciest products currently in the sales rooms. Of course, diamond-studded designs come with large price tags, such as Piaget’s Emperador Temple at $3.3 million and Cartier’s phoenix-shaped wristwatch at $2.7 million. Other pieces stand by their technical merits, such as Frank Muller’s Aeternitas Mega 4, with 36 complications, at $2.7 million. Louis Moinet’s new piece, Meteoris, is a $4.6 million set of four tourbillion watches, made using four meteorites from space and comes with a planetarium of the solar system.
