Known as a ‘grail’ watch, highly covetable and superbly desirable, this Patek Philippe timepiece is one of the most mythical and in the horological world—befitting of a brand that has created some of the best men’s watches of all time.

The watch is known as the Silk Road. Its standout feature is a dial featuring a map of Eurasia. It also boasts a world time complication, dual crown, 41-city ring, and is both elaborate and instantly iconic at once. Only three yellow gold world timers with this particular dial exist—hence why collectors are willing to pay over $7.5 million to own one.
