PPM Factory Patek Philippe Aquanaut 5261 40mm Steel Green Rubber Strap Green Dial

PPM Factory Patek Philippe Aquanaut Luce 5261R-001 Weighted 128g

The PPM Factory Patek Philippe Aquanaut Luce Annual Calendar reference 5261R-001 is a weighted automatic mechanical configuration with a supplied total weight of approximately 128g.

This PPM version combines a 26-330-style integrated automatic movement with annual calendar functions, including date, day, month, and moon-phase indications.

The weighted construction uses a combination of high-density material and stainless steel, rather than describing the entire case structure as solid tungsten. Other notable features include a three-dimensional embossed dial, luminous Arabic numerals, sapphire crystal, fluororubber strap, and double-push folding clasp.

Approximately 128g Weighted Construction

One of the most important measurable specifications of this PPM configuration is its total supplied weight:

Approximately 128g

This figure provides a useful reference when comparing different 5261R versions.

However, total weight alone does not determine how a watch feels on the wrist. The location of the additional mass within the case, caseback, clasp, and other components can significantly affect balance.

For this reason, the 128g figure should be considered together with the actual construction and weight distribution.

High-Density Weighted Structure

According to the supplied PPM specification, the weighted construction combines high-density material with stainless steel.

The precise composition of the high-density material has not been provided, so it should not be assigned a specific alloy designation without additional material information.

This is more technically accurate than describing the watch simply as a “tungsten version” when its actual material structure has not been independently established.

26-330-Style Integrated Automatic Movement

The PPM 5261R-001 uses a 26-330-style integrated automatic mechanical movement.

The movement configuration supports the principal calendar and timekeeping displays of this version, including:

* Time display
* Date
* Day
* Month
* Moon phase
* Annual calendar

For technical accuracy, this should be identified as a 26-330-style movement configuration rather than a genuine Patek Philippe-manufactured calibre.

Annual Calendar Function

The annual calendar is one of the most important complications of the 5261R-001.

An annual calendar is designed to distinguish automatically between months containing 30 and 31 days.

This reduces the need for manual date correction during those months.

However, an annual calendar is not the same as a perpetual calendar. February still requires correction because its length changes between regular and leap years.

This distinction is important when documenting the movement accurately.

Date, Day and Month Displays

The movement integrates date, day, and month information into the dial layout.

These indications form part of the annual-calendar mechanism rather than functioning as purely decorative subdials.

Their positioning allows several calendar indications to be displayed while retaining the recognizable Aquanaut dial architecture.

Moon-Phase Display

The PPM movement configuration also incorporates a functional moon-phase display.

The moon-phase indication adds an astronomical display to the annual-calendar architecture and changes progressively as the mechanism advances.

It should not be confused with the month display: the two functions are mechanically and visually separate indications.

Three-Dimensional Embossed Dial

The dial uses a three-dimensional embossed surface.

This textured construction creates visible depth across the dial and is one of the defining visual elements of the Aquanaut design language.

Because the pattern is physically formed rather than represented solely by printing, lighting from different directions can change the apparent depth and contrast of the dial.

Luminous Arabic Numerals

The Arabic numeral hour markers incorporate luminous material for improved visibility under reduced lighting.

The supplied information describes the numerals as having a filled, rounded appearance.

Actual lume intensity and duration can vary depending on charging conditions and individual production batches, so no fixed brightness or duration is assigned here.

Pfinodal-Style Alloy Hands

The supplied specification identifies the hands as using a Pfinodal alloy configuration with white luminous material.

Pfinodal is a copper-based alloy family associated with particular mechanical properties, but the exact material composition of the hands on this PPM version has not been independently analyzed.

For this reason, the most appropriate description is Pfinodal-style alloy hands based on the supplied specification.

Sapphire Crystal

The watch is fitted with a sapphire crystal.

Its transparency allows the dial texture, calendar displays, moon-phase indication, and luminous markers to remain clearly visible.

No specific anti-reflective coating specification has been provided, so additional coating claims are not included.

Fluororubber Strap

The PPM version uses a fluororubber strap.

Fluororubber is commonly selected where flexibility, chemical resistance, and durability are useful characteristics.

The strap also forms an important part of the Aquanaut’s overall appearance, continuing the sporty design language established by the embossed dial.

Double-Push Folding Clasp

The supplied strap is paired with a double-push folding clasp.

The folding mechanism allows the strap to open widely for fitting while remaining attached as a continuous assembly.

Push-button release provides a controlled method of opening the clasp during normal use.

Why the 128g Weight Matters

The approximately 128g total weight is particularly useful because it gives this PPM version a measurable specification that can be compared with other 5261 configurations.

Simply stating that a watch is “weighted” provides relatively little technical information.

Recording the actual weight makes comparisons much clearer.

At the same time, two watches that both weigh 128g can still feel different because of how their mass is distributed.

This is why total weight should ideally be evaluated together with the construction of the case, caseback, clasp, and other weighted components.

Integrated Movement vs. Decorative Movement

The supplied PPM specification describes the movement as an integrated 26-330-style configuration.

This distinction is useful because a movement that mechanically supports the calendar indications differs from a basic movement that has been visually modified primarily to resemble another calibre.

For technical documentation, the most useful questions are therefore whether the date, day, month, moon phase, and annual-calendar logic operate mechanically as intended, rather than relying only on the appearance of the movement.

Annual Calendar vs. Perpetual Calendar

The 5261R-001 should be described as an annual-calendar watch.

An annual calendar recognizes the difference between 30-day and 31-day months.

A perpetual calendar goes further by accounting for February and leap-year cycles.

Therefore:

Annual Calendar ≠ Perpetual Calendar

Keeping this distinction clear prevents the movement’s complication from being overstated.

Weighted Material and Surface Finishing

The supplied information describes a construction combining high-density material and stainless steel.

This is preferable to making assumptions about the exact weighting alloy.

Without a material-composition analysis, claims such as “solid tungsten,” specific alloy percentages, or guaranteed long-term coating performance should not be treated as confirmed technical specifications.

If material testing becomes available later, the exact composition can then be added to the page.

These are much stronger technical identifiers than subjective descriptions such as “ultimate version” or “best version.”

Wearing and Adjustment

Because the movement incorporates multiple calendar indications, calendar adjustment should be performed carefully.

The crown or calendar correctors should never be forced if unusual resistance is encountered.

If the watch has stopped for an extended period, the time and calendar should be reset using the correct adjustment sequence for the movement.

Strong impacts and powerful magnetic fields should also be avoided.

No verified water-resistance rating has been supplied for this PPM configuration, so intentional water exposure should be avoided unless the individual watch has passed an appropriate pressure test.
