At The Second Hand Club, we are proud to present one of the most significant modern Patek Philippe releases of the last decade: the Aquanaut Chronograph reference 5968A-001 in stainless steel with orange chronograph accents. Introduced at Baselworld 2018, the 5968A was Patek Philippe's first chronograph in the Aquanaut collection, and the decision to launch it in steel, with orange detailing on the dial and a matching orange composite strap, signalled a willingness from Geneva's most conservative maison to engage with a younger, more expressive generation of collectors. The 42.2 mm case houses the self-winding Calibre CH 28-520 C, a column wheel and vertical clutch flyback chronograph with a power reserve of up to 55 hours, representing Patek Philippe's finest chronograph engineering in a sports watch format. The embossed black dial with its orange chronograph hand, orange sixty-minute counter, and orange elapsed-time scale delivers a visual energy that no other Patek Philippe in current production can match. For collectors seeking a pre-owned Patek Philippe Aquanaut Chronograph 5968A for sale, this is the watch that proved Patek could make a steel sports chronograph as compelling as anything from its competitors, while remaining unmistakably itself.
