The 42.2 mm stainless steel case is constructed with a mix of satin-brushed surfaces and polished bevels, delivering both durability and refined finishing. Its black embossed dial features the signature Aquanaut pattern, enhanced by vivid orange chronograph hands and minute scale for improved timing visibility. At the core is the self-winding Caliber CH 28-520 C, a flyback chronograph movement equipped with a column wheel and vertical clutch system, allowing seamless restart without stopping the chronograph. Operating at 28,800 vibrations per hour, it provides stable precision and a power reserve ranging between 45 and 55 hours. The sapphire crystal case back reveals fine finishing details including Geneva stripes and a 21k gold rotor. Water resistance is rated to 120 meters, supported by a screw-down crown and a composite tropical strap designed for resistance to wear, UV exposure, and moisture.

What distinguishes this reference is its assertive character. The integration of vibrant accents into a traditionally restrained manufacture introduces a new visual energy while maintaining mechanical seriousness. It is a sports chronograph built for real-world use, yet executed with the discipline and finishing standards expected from Patek Philippe.

Patek Philippe Aquanaut Chronograph 5968A-001

Reference: 5968A-001
Collection: Aquanaut Chronograph
Case material: Stainless steel
Case diameter: 42.2 mm
Case thickness: 11.9 mm
Water resistance: 30 m according to Patek Philippe’s current technical page.

This reference introduced the first chronograph in the Aquanaut collection. Patek Philippe’s original launch documentation describes the 5968A-001 as a self-winding flyback chronograph developed specifically for the sporty character of the Aquanaut.

Dial

Color: Sunburst charcoal gray with black-gradient rim

Hands: White-gold baton style with white luminescent coating
Chronograph indications: Central chronograph hand and 60-minute counter at 6 o’clock

The chronograph indications are distinguished by orange accents, creating the strong contrast that characterizes the 5968A-001. Patek Philippe’s launch documentation specifically notes the orange chronograph hand, peripheral railway-track scale and 60-minute counter.

Important historical specification

There is a notable difference between Patek Philippe’s original launch documentation and the current technical page concerning water resistance.

The original 2018 launch material states 120 m water resistance for the 5968A-001, whereas Patek Philippe’s current technical page lists 30 m.

For our final product page, I would not silently choose one figure. We should present the current factory technical specification as the primary specification and, if discussing the historical launch specification, explicitly identify it as such.
