Testing Note
These readings were recorded from this individual watch during its pre-shipment QC inspection.
Mechanical movement performance can vary depending on mainspring power reserve, watch position, ambient temperature and testing conditions. The recorded +8 seconds/day represents the movement’s performance at the time of inspection and should not be interpreted as a permanently fixed daily rate.
For QC evaluation, the daily rate should be considered together with amplitude, beat error and actual movement functionality.
3230 Movement Performance
This Clean Factory Rolex Oyster Perpetual 124300-0005 is equipped with a 3230 automatic movement, operating at 28,800 vibrations per hour.
During this QC inspection, the movement recorded:
* Daily Rate: +8 Seconds/Day
* Amplitude: 275°
* Beat Error: 0.0 ms
* Beat Rate: 28,800 BPH
The movement showed stable performance under the recorded testing conditions.
Because the Oyster Perpetual uses a relatively straightforward time-only configuration, movement inspection can focus on the essential mechanical functions, including automatic winding, manual winding and time setting.
Case Dimensions and Weight
The individual watch inspected measured:
* Case Diameter: 41.0 mm
* Case Thickness: 12.0 mm
* Measured Weight: 135.4 g
These measurements provide actual QC reference data for this specific 124300-0005.
The 135.4 g figure represents this individual watch rather than a fixed weight for every piece. Bracelet sizing and normal production tolerances may result in small differences between watches.
Sapphire Crystal and Dial Inspection
The watch uses a sapphire crystal, which should be inspected for clarity, surface condition and correct installation.
The Oyster Perpetual has a relatively clean dial layout, which makes small alignment or finishing differences easier to notice during close inspection.
QC should therefore include:
* Sapphire crystal condition
* Dial surface and printing
* Hour-marker alignment
* Hand alignment
* Crown operation
* Case finishing
* Bracelet-to-case fit
* Clasp operation
Checking these details individually provides a more useful assessment than relying only on the factory name.
Exterior Finishing and Assembly
One of the stronger aspects observed on this Clean Factory 124300-0005 is its overall exterior finishing and assembly quality.
The inspected watch showed clean case finishing, consistent dial presentation, well-aligned hands and hour markers, and good bracelet integration.
Because the Oyster Perpetual has a simple overall design without a date window, rotating bezel or additional complications, the quality of the basic components becomes particularly noticeable.
The case, dial, hands, crystal and bracelet therefore have a significant influence on the overall appearance of the watch.
On the individual watch inspected, these areas showed a high level of consistency with no obvious finishing issue identified during the final visual inspection.
QC Observations
The Clean Factory Rolex Oyster Perpetual 124300-0005 demonstrated stable movement performance and strong exterior finishing during this inspection.
The 3230 movement recorded +8 seconds/day, 275° amplitude and 0.0 ms beat error at a beat rate of 28,800 BPH.
The individual watch measured:
* 41.0 mm in diameter
* 12.0 mm in thickness
* 135.4 g in weight
From an exterior perspective, the overall workmanship was one of the strongest aspects of the inspected watch. The case finishing, dial details, hand and marker alignment, sapphire crystal and bracelet assembly were all executed consistently.
No obvious issue requiring special attention was identified during the visual inspection of this individual watch.
Overall, this Clean Factory 124300-0005 showed a well-balanced combination of movement performance, case proportions, exterior finishing and assembly quality. As always, final assessment should still be based on the actual QC results of each individual watch rather than factory reputation alone.
