Brand new in 42mm rosegold casing with flyback chronograph and annual calendar functions. Uniting two Patek Philippe complications highly prized amongst connoisseurs – a self-winding flyback chronograph and a patented Annual Calendar –, the Ref. 5905 now comes in a new version with a rose gold case and brown sunburst dial, gradually grading to black at the periphery. Because the vertical clutch is virtually friction-free, the center chronograph hand can also serve as a permanent seconds hand.
