The Patek Philippe Flyback Chronograph unites two complications into one--a self-winding flyback chronograph and a patent Annual calendar. Designed with a 42mm rose gold case and brown sunburst dial, it features a date/night display. Because the vertical clutch is virtually friction-free, the center chronograph hand can also serve as a permanent seconds hand. It is finished with a sapphire-crystal back, black alligator strap and prong buckle.
