Grand Tourbillion Heures Mysterieuses in platinum
Price: $365,750
Although once known primarily for its signature fountain pens, Richemont-owned Montblanc in recent years has transformed its brand into that of a jeweler and watchmaker. Its most expensive watch is the Grand Tourbillion Heures Mysterieuses in platinum, of which only one has been made so far. This tourbillion is also available in 18 carat white gold (in photo), limited to eight pieces at $319,000 each. The 18 carat red gold version, also limited to eight pieces, is $302,500.
