AOF Factory IWC Pilot Top Gun Lake Tahoe IW328104 — Actual QC Test & Measurements
Product Overview
This QC report documents an individual AOF Factory IWC Pilot’s Watch Automatic TOP GUN Lake Tahoe IW328104, featuring a white ceramic case, black dial, textile strap and 2892 automatic movement.
The purpose of this report is to provide actual movement performance and physical measurement data from the inspected watch, with particular attention to the ceramic case construction, case dimensions and overall weight.
The recorded results provide a reference for comparing individual AOF production samples and other versions of the IW328104.

What We Found During This QC
1. 2892 Movement Recorded +10 Seconds/Day
The 2892 automatic movement was tested using a Timegrapher and recorded:
+10 sec/day · 307° amplitude · 0.0 ms beat error · 28,800 BPH
The recorded daily rate falls within the approximately ±0–15 seconds/day reference range used for our pre-shipment movement evaluation.
The 307° amplitude and 0.0 ms beat error provide additional information about the movement’s performance under the recorded testing conditions.
These readings should be considered together rather than evaluating movement quality solely from the daily rate.
A single Timegrapher test does not establish long-term accuracy or performance across different positions and power-reserve levels.
2. Actual Case Measurements: 41.1mm × 11.5mm
Caliper measurements recorded:
* Case Width: 41.1 mm
* Case Thickness: 11.5 mm
The measured width is consistent with the model’s nominal 41 mm size category.
The 11.5 mm thickness provides a useful physical reference when comparing the case profile of this version with other Pilot’s Watch configurations.
Because ceramic cases have different material characteristics from conventional steel cases, dimensional accuracy and case-edge finishing are particularly relevant inspection points.
3. Actual Weight: 95.1g
The complete watch weighed 95.1 g during this QC inspection.
This measurement is particularly useful because the IW328104 combines a ceramic case with a textile strap rather than a conventional full-steel case and bracelet.
The resulting configuration provides a relatively lightweight overall construction.
However, weight alone should not be interpreted as proof of ceramic composition or manufacturing quality.
The 95.1 g result applies to the inspected watch and its specific strap configuration.
White Ceramic Case Inspection
The white ceramic case is one of the most distinctive characteristics of the Lake Tahoe design.
Unlike polished stainless steel, ceramic surfaces require particular attention to edge condition, surface uniformity and possible chips.
For this model, the most relevant inspection areas include:
* White ceramic surface consistency
* Case-edge finishing
* Visible chips or surface damage
* Case symmetry
* Lug condition
* Crown integration
* Caseback alignment
* Overall assembly
The white exterior makes certain marks or contamination easier to notice, particularly around case edges and contact points.
Close-up QC photographs taken under neutral lighting are useful for examining the ceramic surface without excessive reflections or color distortion.
Black Dial Inspection
The black dial creates strong contrast with the white ceramic case.
The dial inspection focuses on the consistency of the printed numerals, hour markers, hands and date display.
Important points include:
* Black dial surface condition
* Arabic numeral printing
* Minute-track alignment
* IWC logo positioning
* Hand alignment
* Date-window positioning
* Date numeral centering
* Luminous application
* Dial cleanliness
Because the design relies on high contrast and relatively large printed elements, alignment and printing inconsistencies can be noticeable in close-up photographs.
2892 Automatic Movement Function Inspection
Timegrapher results provide useful performance data, but they do not replace practical movement-function testing.
For the 2892-based automatic movement, the relevant inspection includes automatic winding, manual winding, crown engagement, time setting, date adjustment and normal running operation.
The movement should operate without unusual resistance or interruption during normal adjustment.
This 2892-based configuration should also be distinguished from the genuine manufacturer’s movement architecture. Similar external appearance does not establish identical internal construction.
Sapphire Crystal Inspection
The supplied specification identifies a sapphire crystal.
The most useful crystal inspection points include clarity, surface condition, edge condition, correct installation and visibility of the dial.
For a pilot-style watch with a relatively large dial opening, crystal clarity and the appearance of the dial from different viewing angles are particularly relevant.
Reflections alone should not be treated as proof of sapphire material or anti-reflective coating performance.
Textile Strap and Wearing Configuration
The textile strap is an important part of this model’s overall construction and measured weight.
Compared with a full-steel bracelet configuration, a textile strap generally contributes less weight and offers a different wearing feel.
Relevant inspection points include:
* Strap stitching
* Fabric surface condition
* Strap-to-case connection
* Hole finishing
* Buckle operation
* Strap alignment
* Visible wear or loose threads
The combination of the white ceramic case and textile strap is particularly relevant when interpreting the measured 95.1 g weight.
QC Findings and Assessment
The most useful findings from this AOF Factory IW328104 sample are the combination of movement readings and actual physical measurements:
+10 sec/day · 307° amplitude · 0.0 ms beat error · 28,800 BPH
41.1 mm width · 11.5 mm thickness · 95.1 g weight
The 2892 movement recorded readings within the stated pre-shipment QC reference range.
The physical measurements document a relatively lightweight ceramic-case and textile-strap configuration.
For this reference, the most important exterior inspection areas are the white ceramic surface, case edges, black dial printing, date alignment and strap assembly.
These sample-specific results provide a more useful technical reference than general claims about factory reputation or overall quality.
QC Status
Movement Data Assessment: Within QC Reference Range
Physical Measurements: Recorded
Final Shipment Status: Subject to completion of functional and exterior inspection.
The recorded movement and measurement data alone do not establish that every exterior and functional inspection item has passed.
FAQ
What movement does the AOF Factory IWC Lake Tahoe IW328104 use?
The inspected watch uses a 2892 automatic movement operating at 28,800 BPH.
What were the actual Timegrapher readings?
The sample recorded +10 seconds/day, 307° amplitude and 0.0 ms beat error.
What are the actual case dimensions?
The inspected case measured 41.1 mm in width and 11.5 mm in thickness.
How much does the AOF Factory IW328104 weigh?
The complete inspected watch weighed 95.1 g with its textile strap configuration.
Why is the Lake Tahoe version relatively lightweight?
The watch combines a ceramic case with a textile strap rather than a conventional full-steel case and bracelet. The measured weight also depends on the exact construction of the individual watch.
What should be inspected carefully on a white ceramic watch?
The ceramic surface, case edges, possible chips, crown integration, dial printing, crystal condition and strap connections are particularly relevant QC areas.
