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, watch position, ambient temperature and testing conditions. A single timegrapher result represents the movement’s condition at the time of inspection rather than a permanently fixed daily rate.
3235 Movement Performance
This Clean Factory Rolex Submariner Date 126613LB is equipped with a 3235 automatic movement operating at 28,800 vibrations per hour.
During this QC inspection, the movement recorded a +5 seconds/day rate, 244° amplitude and 0.3 ms beat error.
The movement operated consistently under the recorded testing conditions. In addition to the timegrapher readings, automatic winding, manual winding, time setting and date adjustment should be tested individually before shipment.
For QC purposes, the actual movement performance of each individual watch is more useful than relying only on the movement name or factory reputation.
Case Dimensions and Weight
The inspected watch measured:
* 41.0 mm in diameter
* 12.4 mm in thickness
* 158 g in weight
These measurements provide useful reference data for this individual 126613LB.
Weight may vary slightly between individual watches depending on bracelet sizing and manufacturing tolerances, so 158 g should be treated as the measured weight of this QC sample rather than a fixed specification for every watch.
Exterior and Assembly Inspection
The 126613LB combines several exterior components that deserve individual inspection before shipment.
Particular attention should be given to:
* Dial and hour-marker alignment
* Hand alignment
* Date-window positioning
* Cyclops alignment
* Bezel insert alignment
* Bezel rotation
* Case finishing
* Bracelet assembly
* Clasp locking and adjustment
These areas should be checked on the actual watch because small differences can occur between individual pieces and production batches.
QC Observations
The Clean Factory Rolex Submariner 126613LB showed a high level of overall finishing during this inspection.
The case proportions, dial presentation, bezel assembly, bracelet construction and general exterior finishing were all well executed on the inspected watch.
The 3235 movement also produced stable recorded results, including a +5 seconds/day rate, 244° amplitude and 0.3 ms beat error.
In the current market, Clean Factory is one of the better-established options for this model. Other versions commonly compared in the same category include VS Factory and Victory Factory, while additional factory versions may also be available depending on the production period.
Rather than declaring one factory universally superior, the more useful comparison is between the actual watches. Movement performance, dial details, bezel construction, case finishing, bracelet assembly and individual QC results can vary between batches.
Based on the individual watch inspected here, the Clean Factory 126613LB showed a strong combination of exterior finishing, dimensions and movement performance, making it a version worth considering within the current market.
