The very first chronograph in the Aquanaut collection. The sporty and very contemporary Aquanaut collection welcomes its first chronograph – a complication that perfectly matches the character of this youthful and dynamic timepiece line. Patek Philippe endowed this companion for active people with a self-winding flyback chronograph movement that combines tradition and innovation. It features a classic column wheel as well as a modern vertical disk clutch that prevents a rebound of the hand in either direction when the chronograph is started. Because this clutch is virtually friction-free, the chronograph hand can also be used as a continuously running seconds hand.
