GR Factory Patek Philippe Nautilus 5711 Technical Guide
The GR Factory Patek Philippe Nautilus 5711 series is offered in multiple decorative configurations with 35.2mm and 40mm size options, a 324SC-style automatic movement and stone-set exterior variations.
According to the supplied specifications, the movement is based on a customized 9015 architecture modified to reproduce the visual and functional layout of a Cal.324SC-style automatic movement. The stated operating frequency is 28,800 vibrations per hour, with an approximately 45-hour power reserve.
The collection also includes several colored stone-set configurations across the bezel and bracelet.
Rather than treating all versions as a single specification, the GR 5711 series is more useful when documented by case size, movement architecture, dial configuration and stone-set variation.
35.2mm and 40mm Size Options
The supplied GR Factory specifications identify two available sizes:
- 35.2mm
- 40mm
These should be treated as separate production configurations rather than assuming that both dimensions represent the same historical 5711 specification.
Case thickness and actual weight were not supplied and should therefore be measured separately during QC.
This is particularly important for stone-set versions because exterior decoration can affect overall weight.
Nautilus-Style Case Architecture
The case follows the recognizable Nautilus-style geometry, characterized by a rounded-octagonal bezel and horizontally integrated case construction.
The bracelet transitions directly into the case rather than using a conventional strap-and-lug arrangement.
Useful exterior QC points include:
- Bezel alignment
- Case symmetry
- Brushing
- Polished transitions
- Crown positioning
- Bracelet-to-case fit
- Clasp operation
These characteristics can be evaluated independently from the decorative stone setting.
Dial Configurations
The supplied information indicates that the GR 5711 series is available with multiple dial treatments.
Because exact dial colors for all configurations were not individually specified, they should be recorded by SKU or individual watch rather than assuming every stone-set variation uses the same dial.
For QC, useful dial inspection points include surface finishing, horizontal texture, printing, applied markers, hand alignment and date-window positioning.
324SC-Style Automatic Movement
The GR Factory 5711 is described as using a customized 9015-based movement modified into a Cal.324SC-style configuration.
This distinction is important.
It should not simply be described as a genuine-specification 324SC or an integrated 324SC movement because the supplied information specifically identifies the underlying architecture as being derived from a 9015 movement.
For a technical database, the more accurate classification is:
Customized 9015 Base → 324SC-Style Architecture
This makes it easier to distinguish this version from other 5711 configurations using different movement constructions.
28,800 VPH Operating Frequency
The supplied movement specification lists an operating frequency of 28,800 vibrations per hour (4Hz).
Beat rate is useful when comparing different movement versions because it can be independently checked on a timegrapher during QC.
The individual watch should therefore be tested rather than relying solely on the stated movement specification.
Approximately 45-Hour Power Reserve
The supplied specifications state an approximate 45-hour power reserve.
Power reserve should be distinguished from kinetic energy; it refers to how long a fully wound mechanical movement continues operating before its stored mainspring energy is depleted.
For database purposes, the most useful method is to record both:
Factory Stated Power Reserve: Approx. 45 Hours
and, when available:
QC Measured Power Reserve: XX Hours
This allows the stated specification and real-world test result to be compared directly.
Decorative Stone-Set Configurations
The series includes several colored stone-set styles.
The supplied description refers to red, blue, green and clear/white stones.
However, without independent gemological verification, these should not automatically be classified as natural:
- Ruby
- Sapphire
- Emerald
- Diamond
Instead, the database should identify them according to their observable appearance:
Red Decorative Stones
Blue Decorative Stones
Green Decorative Stones
Clear/White Decorative Stones
If material certificates or testing become available later, the specific gemstone composition can then be added.
Stone Setting and QC
Stone-set watches require several additional QC checks compared with conventional steel configurations.
Useful inspection areas include:
- Stone alignment
- Spacing consistency
- Setting height
- Color consistency
- Bezel symmetry
- Bracelet articulation
- Missing or loose stones
- Surface scratches around the settings
Macro photography is particularly useful because inconsistencies that are difficult to see at normal viewing distance become more apparent under magnification.
316L Bracelet Construction
The supplied specifications identify the bracelet material as 316L stainless steel.
The bracelet follows an integrated construction that transitions directly into the case.
Useful bracelet inspection points include:
- Link articulation
- Brushed surfaces
- Polished sections
- Edge finishing
- Stone alignment where applicable
- Clasp engagement
For stone-set configurations, bracelet flexibility should also be checked because decorative settings should not interfere with normal link articulation.
Sapphire Crystal
The supplied specification identifies a sapphire crystal with anti-reflective treatment on both sides.
Anti-reflective coating can reduce visible reflections and improve dial visibility under certain lighting conditions.
QC photographs should still be taken under several lighting angles because reflections vary considerably depending on the position of the light source.
Movement and Exterior Quality Should Be Evaluated Separately
A heavily decorated exterior does not provide information about mechanical performance.
For this reason, the GR 5711 database should separate three areas:
Movement Performance → Case & Bracelet Construction → Decorative Stone Setting
This allows an individual watch to have strong exterior finishing without automatically assuming that its movement performance is equally strong, or vice versa.
What to Check During QC
For a GR Factory 5711, useful QC records include:
- Case Size
- Case Thickness
- Actual Weight
- Daily Rate
- Amplitude
- Beat Error
- Beat Rate
- Power Reserve
- Automatic Winding
- Date Operation
- Dial Alignment
- Stone Alignment
- Stone Color Consistency
- Bracelet Articulation
- Clasp Operation
- Crystal Condition
For the 35.2mm and 40mm versions, measurements should be stored separately rather than combined into one QC specification.

Frequently Asked Questions
- What movement does the GR Factory 5711 use?
According to the supplied specifications, it uses a customized 9015-based automatic movement modified into a 324SC-style configuration.
- What sizes are available?
The supplied GR Factory information lists 35.2mm and 40mm configurations.
- What is the movement frequency?
The stated operating frequency is 28,800 vibrations per hour, or 4Hz.
- What is the power reserve?
The supplied specification states approximately 45 hours. An individual QC power-reserve test can be used to verify actual running time.
- Are the colored stones natural rubies, sapphires, emeralds and diamonds?
That cannot be established from the supplied information. Without independent gemological testing, they are more accurately documented as red, blue, green and clear/white decorative stones.
- Is the GR Factory 5711 movement an integrated 324SC?
The supplied information specifically describes it as a customized 9015-based movement modified into a 324SC-style configuration. It should therefore be distinguished from versions using a different or fully integrated movement architecture.
