Product Detailed Description

PPF Factory Patek Philippe Nautilus 5726 40mm Automatic Watch

The PPF Factory Patek Philippe Nautilus 5726 combines the recognizable Nautilus sports-watch design with a more complex calendar display.

This configuration features a 40mm stainless steel case, horizontally striped dial, full stainless steel bracelet and 324 S QA LU 24H/303 automatic mechanical movement.

In addition to conventional timekeeping, the movement configuration incorporates date, day, month, moon-phase and 24-hour indications, creating a more information-rich dial while retaining the characteristic Nautilus case and bracelet architecture.

40mm Stainless Steel Case

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

The broad bezel, integrated lugs and alternating case surfaces give the watch a different appearance from conventional round sports watches.

At 40mm, the case maintains a balanced wrist presence while providing sufficient dial space for the additional calendar indications.

Horizontally Striped Dial

The dial features the characteristic horizontal striped pattern associated with the Nautilus collection.

These repeated grooves add texture across the dial and create subtle visual changes under different lighting conditions.

The striped background also provides separation between the primary time display and the multiple calendar indications.

Annual Calendar Display

One of the defining technical characteristics of the Nautilus 5726 configuration is its annual calendar display.

The dial provides separate indications for:

Date
Day
Month

An annual calendar is designed to distinguish between 30-day and 31-day months, reducing the number of manual calendar corrections required during normal use.

This complication gives the 5726 a substantially different functional character from standard three-hand Nautilus models.

324 S QA LU 24H/303 Automatic Movement

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

Its functions include:

Hours
Minutes
Seconds
Date
Day
Month
Moon phase
24-hour indication

Automatic winding allows normal wrist movement to replenish the movement’s power reserve during regular wear.

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

Moon-Phase Display

The dial incorporates a moon-phase indication that visually represents the progression of the lunar cycle.

The moon-phase display is integrated with the calendar layout rather than being treated as a separate decorative element, contributing to the technical character of the 5726.

24-Hour Indication

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

This can also be useful when adjusting calendar functions, since mechanical calendar mechanisms should generally be handled carefully around their automatic changeover period.

Avoid forcing calendar adjustments if unusual resistance is encountered.

Sapphire Crystal with Anti-Reflective Coating

The watch is fitted with a sapphire crystal featuring an anti-reflective coating.

Sapphire provides high scratch resistance and excellent optical transparency, while the anti-reflective treatment helps reduce glare when viewing the striped dial and calendar indications.

Strong direct impacts against hard surfaces should still be avoided.

Full Stainless Steel Bracelet

The Nautilus 5726 is paired with a full stainless steel bracelet that integrates visually with the case.

The bracelet continues the sports-watch character of the design while providing a different wearing experience from leather-strap configurations.

Regular cleaning with a soft microfiber cloth can help remove fingerprints, sweat and surface residue from the bracelet and case.

Folding Clasp

The stainless steel bracelet is secured using a folding clasp.

This design keeps the bracelet connected when opened and provides a secure closure for regular daily wear.

The clasp and bracelet should be checked periodically for loose screws, excessive play or other signs of wear.

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 crown, seals, crystal installation and overall case assembly.

If the watch will be used for swimming or regular water exposure, professional pressure testing is recommended beforehand.

Wearing and Care Advice

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

Avoid abrasive polishing products if you want to preserve the original contrast between brushed and polished surfaces.

Calendar functions should be adjusted carefully. Avoid forcing the calendar mechanism if resistance is felt, particularly during the movement’s automatic date-change period.

Protect the automatic movement from strong magnetic fields and heavy impacts.

Professional pressure testing is recommended before swimming or prolonged water exposure.
