PPF Factory Patek Philippe Nautilus 57261A-0014 40mm Leather Strap Blue Dial

Product Detailed Description

PPF Factory Patek Philippe Nautilus 5726 40mm Automatic Watch

The PPF Factory Patek Philippe Nautilus 5726 combines the recognizable Nautilus case profile with an annual calendar layout and a black calfskin leather strap.

This configuration features a 40mm stainless steel case, horizontally striped dial, sapphire crystal with anti-reflective coating and a 324 S QA LU 24H/303 automatic mechanical movement.

The movement configuration incorporates time, calendar, moon-phase and 24-hour indications, giving the 5726 a more complicated dial arrangement than standard three-hand Nautilus models.

40mm Stainless Steel Case

The watch features a 40mm stainless steel case built around the characteristic Nautilus profile.

Its broad bezel and integrated case architecture create the recognizable sports-watch appearance of the collection, while the 40mm dimensions provide a balanced presence on the wrist.

The stainless steel construction also creates a strong visual contrast with the black calfskin strap used on this configuration.

Horizontally Striped Dial

The dial features a horizontal striped pattern, adding texture and visual depth across the surface.

These repeated horizontal grooves interact with changing light while providing a structured background for the multiple calendar indications.

The combination of a striped dial and additional complications gives the 5726 a more technical appearance while maintaining the recognizable Nautilus design language.

324 S QA LU 24H/303 Automatic Movement

The watch uses a 324 S QA LU 24H/303 automatic mechanical movement configuration.

Its functions include:

24-hour indication

Automatic winding allows normal wrist movement to replenish the movement’s power reserve during everyday use.

Mechanical accuracy can vary depending on power reserve, temperature, resting position and individual wearing habits.

Annual Calendar Display

A defining feature of the Nautilus 5726 is its annual calendar configuration.

The calendar displays the day, date and month, allowing several pieces of calendar information to be read directly from the dial.

An annual calendar is designed to distinguish between 30-day and 31-day months, reducing the need for frequent manual calendar correction during the year.

Moon-Phase Indication

The dial also incorporates a moon-phase display, providing a visual representation of the lunar cycle.

Its integration into the calendar layout adds another mechanical complication without requiring a separate external control or additional case component.

The moon-phase display is one of the details that distinguishes the 5726 from simpler Nautilus references.

24-Hour Display

A 24-hour indication provides an additional reference for distinguishing daytime and nighttime hours.

This function can also be useful when setting calendar indications, helping the wearer understand whether the movement is operating within its daytime or nighttime cycle.

Calendar adjustments should always be performed carefully, particularly around the movement’s automatic calendar-change period.

Sapphire Crystal with Anti-Reflective Coating

The dial is protected by a sapphire crystal with anti-reflective coating.

Sapphire provides high resistance to everyday scratches and excellent optical clarity.

The anti-reflective treatment helps reduce glare and makes the striped dial, calendar windows and moon-phase indication easier to view under different lighting conditions.

Strong direct impacts should still be avoided.

Black Calfskin Leather Strap

This version of the Nautilus 5726 is paired with a black calfskin leather strap rather than a full stainless steel bracelet.

The darker leather creates a more restrained appearance while providing a softer and lighter contact point around the wrist.

Leather straps should be kept away from prolonged exposure to water, sweat, perfumes and chemical cleaning products.

If the strap becomes damp, allow it to dry naturally away from direct heat.

Folding Clasp

The black calfskin strap is secured using a folding clasp.

Unlike a conventional pin buckle, the folding mechanism allows the strap to remain connected when opened.

This construction can also reduce repeated bending of the leather around a traditional buckle during everyday use.

100m Water-Resistance Specification

The supplied specification lists the watch with 100 meters of water resistance.

Actual water resistance depends on the condition of the seals, crown, crystal installation and overall case assembly.

Because this configuration uses a calfskin leather strap, prolonged water exposure should be avoided even when the case has been pressure tested.

Wearing and Care Advice

Clean the stainless steel case periodically with a soft microfiber cloth to remove fingerprints and surface residue.

Avoid abrasive polishing compounds if you want to preserve the original case finishing.

The black calfskin strap should be protected from prolonged moisture, sweat, perfumes and chemical cleaners. Allow the leather to dry naturally if it becomes damp.

Calendar functions should be adjusted carefully. Avoid forcing the mechanism if resistance is encountered, particularly around the automatic date-change period.

Professional pressure testing is recommended before intentional water exposure.
