The Flyback Chronograph Annual Calendar Ref. 5905 is a wristwatch by Patek Philippe.

Sporty flyback chronograph with steel case and olive green dial. Also available as gold version with rose gold case and brown sunburst dial.

An annual calendar indicates the day of the week, the date and the month, and requires correction only once a year. Because the vertical clutch is virtually friction-free, the center chronograph hand can also serve as a permanent seconds hand.
