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.
