I. Features of Patek Philippe Aquanaut 5164A-001

1.1 The Movement Inside

At the heart of the Patek Philippe Aquanaut 5164A-001 beats the caliber 324 S C FUS, an automatic movement renowned for its precision, craftsmanship, and reliability. This masterpiece of horology is a symphony of intricate components meticulously assembled by skilled artisans. It offers a power reserve of approximately 45 hours, ensuring that your watch remains accurate and dependable, even during extended periods between wears.


The caliber 324 S C FUS is not merely a workhorse; it is a testament to Patek Philippe’s commitment to perfection. The movement features exquisite finishing, including Geneva stripes, chamfered edges, and a stunning 21-karat gold rotor. Its beauty is not just skin deep; the movement’s performance is equally impressive. It provides exceptional timekeeping accuracy and smooth, consistent operation, ensuring that the Aquanaut 5164A-001 lives up to the brand’s reputation for excellence.


1.2 Complications Galore

The Aquanaut 5164A-001 distinguishes itself through a range of practical and sophisticated complications. Among these, the dual time zone mechanism is a standout feature. It allows wearers to effortlessly track time in two different locations simultaneously, making it an invaluable tool for frequent travelers. The ease with which the second time zone can be adjusted further enhances the watch’s utility and convenience.


Adding to the watch’s functionality is the day/night indicator, a discreet yet highly practical complication. This feature allows wearers to discern between AM and PM hours in the second time zone effortlessly. The day/night indicator is a testament to Patek Philippe’s commitment to enhancing the user experience while maintaining the watch’s elegant and uncluttered design.

1.3 Water Resistance and Durability

The Patek Philippe Aquanaut 5164A-001 is not merely a stylish accessory but also a reliable companion for aquatic adventures. Boasting a water resistance rating of up to 120 meters (approximately 394 feet), it is well-suited for water sports and can withstand the rigors of extreme aquatic environments. Whether you are diving into the depths of the ocean, snorkeling, or simply enjoying a swim in the pool, this watch is designed to endure and perform.

The watch’s durability is further exemplified by its stainless steel case. While steel may not possess the flashy allure of precious metals, it is renowned for its robustness and resilience. The case’s satin and polished finishes add a touch of sophistication to the watch’s sporty design while enhancing its resistance to scratches and wear.

1.4 Size and Dimensions

The dimensions of the Patek Philippe Aquanaut 5164A-001 are carefully considered to strike a balance between presence on the wrist and wearer comfort. With a case diameter of 40.8mm and a case height of 10.2mm, it offers a harmonious blend of elegance and practicality. The watch’s size allows it to make a statement without overwhelming the wrist, ensuring that it is suitable for both formal occasions and casual wear.

The choice of dimensions is complemented by the thoughtful design of the rubber strap. While the rubber strap adds a sporty touch to the watch, it is designed for comfort and durability. Its flexibility ensures a snug fit on the wrist, and it can withstand exposure to water, making it a perfect match for the watch’s aquatic capabilities.

II. Maintenance Tips: Caring for Your Patek Philippe Aquanaut 5164A-001

Owning a Patek Philippe watch is not only a privilege but also a responsibility. Proper care and maintenance are essential to ensure that your Aquanaut 5164A-001 remains in pristine condition and continues to perform flawlessly. Here are some essential tips to help you care for your cherished timepiece:

Regular Servicing

Like any high-precision instrument, your Aquanaut 5164A-001 deserves regular servicing by authorized Patek Philippe watchmakers. The complexity of the movement necessitates expert attention to ensure it operates with the utmost precision and reliability. Regular servicing also allows for the identification and rectification of any potential issues, preserving the watch’s longevity.


Maintaining the pristine appearance of your watch is a crucial aspect of ownership. To do this, use a soft, lint-free cloth to wipe down the case, crystal, and rubber strap regularly. Avoid using abrasive materials or harsh chemicals, as they can damage the watch’s finish and the rubber strap. By gently cleaning the watch, you can ensure that it retains its luster and appeal for years to come.

Water Resistance

While the Aquanaut 5164A-001 is designed for aquatic activities, it is essential to ensure that the crown is securely screwed down before exposing the watch to water. Regularly check the gaskets and seals to maintain the watch’s water resistance. Any signs of wear or deterioration should prompt immediate servicing to prevent water damage to the movement.


Proper storage is crucial to preserving your watch’s beauty and functionality. Store it in a cool, dry place away from direct sunlight, as prolonged exposure can cause the dial’s color to fade and affect the rubber strap’s integrity. Additionally, keep your watch away from magnetic fields, as they can impact its accuracy. If you plan to wear your watch infrequently, consider using a watch winder to keep the movement running smoothly.
