QC Data Reference
These figures were recorded directly from this individual PPM Factory Vacheron Constantin Malte Tourbillon during its pre-shipment QC inspection.
Mechanical movement readings may change depending on mainspring power, watch position, ambient temperature and testing conditions. The recorded +7 seconds/day therefore represents the performance of this individual watch at the time of testing rather than a permanently fixed daily rate.
For QC evaluation, daily rate should be considered together with amplitude, beat error and actual movement operation.
Manual-Winding Tourbillon Movement Test
This PPM Factory Malte 30080/000P-9357 uses a manual-winding tourbillon movement with a beat rate of 21,600 BPH.
Actual QC readings from this watch:
Test Item Measured Result
Daily Rate +7 sec/day
Amplitude 325°
Beat Error 0.3 ms
Beat Rate 21,600 BPH
The movement showed stable readings under the recorded testing conditions.
Because this is a manual-winding movement, there is no automatic rotor. Power must be supplied through the crown, making winding feel and crown operation important parts of the pre-shipment inspection.
Tourbillon Operation Inspection
The tourbillon is the main mechanical feature of this model and should be inspected separately from the basic Timegrapher readings.
QC should check:
* Tourbillon cage rotation
* Rotation consistency
* Visible balance operation
* Abnormal hesitation or stopping
* Manual winding
* Crown operation
* Time-setting operation
* Hand movement and alignment
The tourbillon should continue operating consistently during observation without obvious interruption.
For this type of movement, visual inspection of the tourbillon mechanism provides useful information in addition to the Timegrapher data.
Actual Case Measurements
The individual watch inspected measured:
Measurement QC Result
Case Width 39.6 mm
Case Thickness 13.1 mm
Weight 111.1 g
These figures are actual measurements from the inspected watch, rather than estimated specifications.
The 39.6 mm width provides a relatively compact footprint, while the 13.1 mm thickness reflects the physical construction required by the tourbillon movement and case architecture.
The measured 111.1 g weight applies to this individual QC sample.
Silver Dial Inspection
The silver dial and visible tourbillon architecture make dial cleanliness and component alignment particularly noticeable.
Pre-shipment inspection should include:
* Silver dial surface
* Dial printing
* Hour-marker alignment
* Hand alignment
* Tourbillon opening alignment
* Visible movement components
* Dial cleanliness
* Crystal clarity
The dial should be examined from several viewing angles because reflections from the silver surface can reveal details that may not be obvious from a single front-facing view.
Sapphire Crystal Inspection
This model uses a sapphire crystal.
QC inspection should cover:
* Surface clarity
* Scratches or visible damage
* Correct installation
* Edge condition
* Visual distortion
* Clear visibility of the dial and tourbillon
For a tourbillon model, crystal clarity is especially relevant because the movement architecture forms an important part of the watch’s visual presentation.
QC Observations
The main reference value of this QC report comes from combining actual movement readings, physical measurements and functional tourbillon inspection from the same individual watch.
This PPM Factory Vacheron Constantin Malte Tourbillon 30080/000P-9357 recorded:
* +7 seconds/day
* 325° amplitude
* 0.3 ms beat error
* 21,600 BPH
* 39.6 mm measured width
* 13.1 mm measured thickness
* 111.1 g measured weight
The manual-winding tourbillon movement showed stable readings under the recorded test conditions.
For this model, QC should not rely only on daily-rate figures. The tourbillon cage, manual-winding operation, crown feel and time-setting function are equally important because they directly relate to the mechanical operation of the watch.
These measurements document this individual QC sample and can also provide a useful reference when comparing future production pieces or different versions of the same model.

FAQ
What movement does the PPM Factory Malte Tourbillon use?
The inspected watch uses a manual-winding tourbillon movement operating at 21,600 BPH.
What were the actual Timegrapher results?
This individual watch recorded +7 seconds/day, 325° amplitude and 0.3 ms beat error during testing.
Is this an automatic movement?
No. This version uses a manual-winding movement, so the movement must be wound through the crown rather than relying on an automatic rotor.
What are the actual measured dimensions?
The inspected watch measured 39.6 mm in width and 13.1 mm in thickness.
How much does the watch weigh?
This individual QC sample measured 111.1 g. Small differences between individual watches are possible.
What requires additional attention when QC testing a tourbillon?
In addition to Timegrapher readings, the tourbillon cage operation, balance movement, manual winding, crown operation and time-setting function should be inspected individually.
