Testing Conditions and Data Reference
These figures were recorded directly from this individual AZ Factory Code 11.59 Starwheel during its pre-shipment QC inspection.
Mechanical movement readings can change according to mainspring power, testing position, temperature and other test conditions. The recorded +13 seconds/day therefore represents the performance observed during this specific inspection rather than a guaranteed permanent daily rate.
For our pre-shipment QC reference, a daily deviation within approximately ±0–15 seconds/day is considered within the normal operating range used for this type of movement inspection.
The daily rate should not be evaluated alone. Amplitude, beat error and actual movement operation are also checked before shipment.
4310 Automatic Movement Test
This AZ Factory Audemars Piguet Code 11.59 Starwheel uses a 4310 automatic movement operating at 28,800 vibrations per hour.
Our actual QC measurements for this individual watch were:
Test Item Measured Result
Daily Rate +13 sec/day
Amplitude 296°
Beat Error 0.0 ms
Beat Rate 28,800 BPH
During this inspection, the movement operated normally under the recorded test conditions.
Pre-shipment inspection also includes checking automatic winding, manual winding, crown operation and time adjustment rather than relying only on the Timegrapher numbers.
Actual Case Measurements
The physical measurements recorded from this watch were:
Measurement QC Result
Case Width 40.6 mm
Case Thickness 13.2 mm
Weight 95.9 g
These are actual measurements from the inspected watch, rather than estimated specifications.
The measured 40.6 mm width and 13.2 mm thickness provide a useful reference for understanding the physical proportions of this AZ Factory Starwheel.
The measured weight of 95.9 g applies specifically to this QC sample. Individual watches can show small variations.
Starwheel Display Inspection
The Starwheel display is the defining visual characteristic of the Code 11.59 15212NB.OO.A002KB.01 and requires more detailed inspection than a conventional three-hand dial.
During QC, attention should be given to:
* Starwheel display alignment
* Rotating display operation
* Hour indication positioning
* Minute scale alignment
* Display transition
* Blue dial surface
* Printing consistency
* Visible component alignment
The display should be observed through a complete operating sequence where practical to identify abnormal resistance, misalignment or irregular movement.
Blue Dial and Sapphire Crystal
The blue dial contains multiple visual layers and moving elements, making cleanliness and alignment particularly noticeable.
The sapphire crystal should be checked for:
* Surface clarity
* Scratches or visible damage
* Correct installation
* Edge condition
* Visual distortion
* Clear visibility of the Starwheel display
Viewing the watch from several angles is useful because reflections can reveal surface or assembly details that may not be obvious from a single front-facing photograph.
Case and Exterior Inspection
The Code 11.59 case design contains several different surfaces and structural transitions.
Pre-shipment inspection should therefore include:
* Case-edge finishing
* Brushed surfaces
* Polished surfaces
* Surface transitions
* Case symmetry
* Crown positioning
* Crystal installation
* Strap-to-case connection
* Buckle or clasp operation
These details are inspected on the individual watch because exterior finishing can vary slightly between individual production pieces.
QC Data Observations
The most useful aspect of this QC report is the combination of movement data and physical measurements from the same individual watch.
This AZ Factory Audemars Piguet Code 11.59 Starwheel 15212NB.OO.A002KB.01 recorded:
* +13 seconds/day
* 296° amplitude
* 0.0 ms beat error
* 28,800 BPH
* 40.6 mm measured case width
* 13.2 mm measured thickness
* 95.9 g measured weight
The 4310 automatic movement operated normally during this inspection, while the case dimensions and weight were measured directly from the inspected watch.
For a Starwheel model, the movement reading is only one part of QC. The rotating display, indication alignment, dial assembly, sapphire crystal and exterior finishing should also be checked individually.
These measurements provide a practical reference for comparing future production pieces or different factory versions of the same reference. They should not be interpreted as guaranteed specifications for every individual watch.

FAQ
What movement is used in this AZ Factory Code 11.59 Starwheel?
The inspected watch uses a 4310 automatic movement operating at 28,800 BPH.
What was the actual Timegrapher result?
This individual watch recorded +13 seconds/day, 296° amplitude and 0.0 ms beat error during the QC test.
How large is the AZ Factory 15212NB?
Our inspected watch measured 40.6 mm in width and 13.2 mm in thickness.
How much does this watch weigh?
The individual watch inspected weighed 95.9 g. Small differences between individual watches are possible.
Does the Starwheel display require additional QC?
Yes. In addition to movement testing, the rotating display, indication alignment and operating sequence should be visually and functionally checked before shipment.
Why can Timegrapher readings change?
Mechanical movement readings can vary according to power reserve, position, temperature and testing conditions. The figures in this report document the performance of this individual watch at the time of inspection.
