A NEW VERSION IN ROSE GOLD WITH A BROWN SUNBURST DIAL
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.
