Testing Note
The readings above were recorded from this individual watch during its pre-shipment QC inspection.
Mechanical movement performance may vary depending on mainspring power reserve, watch position, ambient temperature and testing conditions. These results represent the movement’s performance at the time of inspection and should not be interpreted as a permanently fixed daily rate.
9300 Movement Performance
This N1 Factory Speedmaster Dark Side of the Moon is equipped with a 9300 automatic chronograph movement operating at 28,800 vibrations per hour.
During this QC inspection, the movement recorded -3 seconds/day, an amplitude of 276° and a beat error of 0.1 ms.
The movement operated consistently under the recorded testing conditions, with no obvious irregularities observed during the inspection.
Automatic winding, manual winding, time setting and chronograph operation should all be checked individually before shipment.
Functional Chronograph
An important feature of this version is that the chronograph is functional rather than decorative.
The chronograph pushers and corresponding hands are designed to provide actual timing operation. During pre-shipment QC, the chronograph should therefore be tested through a complete operating cycle, including:
* Chronograph start
* Chronograph stop
* Chronograph hand operation
* Subdial operation
* Chronograph reset
* Reset-hand alignment
This is particularly important for a chronograph model because exterior appearance alone cannot confirm whether the timing mechanism is operating correctly.
Ceramic Case and Sapphire Crystal
One of the stronger points observed on this N1 Factory version is the quality of the ceramic case and sapphire crystal.
The ceramic case provides the distinctive appearance associated with the Dark Side of the Moon design, while the sapphire crystal is used on both the front and exhibition caseback.
During QC, the ceramic surfaces should be inspected carefully for scratches, chips, uneven finishing or damage around the case edges.
The sapphire crystal should also be checked for clarity, surface condition and correct installation. Because both materials play an important role in the overall appearance of this model, they deserve individual inspection before shipment.
Important Clasp Inspection
The clasp requires particular attention on this model.
When closing the clasp, it should be pressed into its fully locked position. If the clasp is not completely engaged and is repeatedly used while partially locked, unnecessary stress may be placed on the internal spring mechanism.
Over time, improper engagement could contribute to spring wear or damage.
For this reason, the pre-shipment QC process should specifically check:
* Clasp opening and closing
* Positive locking engagement
* Spring response
* Clasp security after locking
* Strap and clasp alignment
For daily use, the wearer should also confirm that the clasp is fully engaged rather than leaving it partially closed.
QC Observations
The N1 Factory Omega Speedmaster Dark Side of the Moon 311.92.44.51.01.006 showed stable movement performance during this inspection.
The recorded measurements were 43.1 mm in diameter, 17.9 mm in thickness and 101 g in weight.
The 9300 movement produced a -3 seconds/day rate, 276° amplitude and 0.1 ms beat error under the recorded testing conditions.
Another important advantage is the functional chronograph mechanism. The timing functions are operational rather than simply decorative elements on the dial.
The ceramic case and front/rear sapphire crystal are also notable areas of this version, with good overall material presentation during inspection.
The main point requiring additional attention is the clasp locking mechanism. Correct and complete engagement should be confirmed before shipment and during normal use to reduce unnecessary stress on the clasp spring.
Overall, the movement, chronograph operation, ceramic construction and sapphire components are the main areas worth examining on this version, while the clasp should receive additional attention during final QC.
