Patek Philippe is reasserting the "contemporary casual chic" spirit of the Aquanaut flyback chronograph with the first white gold version of this self-winding model, combined with an elegant midnight blue color for the dial and matching composite strap. The dial is enlivened by a black-gradient rim. Water-resistant to 120 m, the case is enhanced by polished and satin finishes. The 60-minute counter at 6 o'clock picks up the rounded octagonal shape of the bezel. The patented fold-over clasp is secured by four independent catches.
