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, watch position, ambient temperature and testing conditions. A single timegrapher result represents the movement’s condition at the time of inspection and should not be interpreted as a permanently fixed daily rate.
Rolex Clone 3285 Movement Performance
This ONE Factory GMT-Master II 126710 is equipped with a Rolex Clone 3285 automatic GMT movement operating at 28,800 vibrations per hour.
During this QC inspection, the movement recorded a daily rate of 0 seconds, an amplitude of 241° and a beat error of 0.0 ms. The results indicate stable operation under the recorded testing conditions.
The 3285 movement provides the functions required for this GMT model, including:
* Automatic winding
* Manual winding
* Time setting
* Independent jumping local hour hand
* GMT hand operation
* Date adjustment linked to the local hour hand
These functions should be tested individually before shipment rather than judged only by the movement name.
GMT Function Inspection
The independent local hour hand is one of the most important functions to inspect on a GMT-Master II 126710.
During pre-shipment QC, the following functions should be checked:
* Local hour hand moves independently in one-hour steps
* GMT hand continues to display the reference time
* Date changes correctly when the local hour hand crosses midnight
* Crown positions engage correctly
* Hands do not interfere with one another
* GMT hand and hour markers remain correctly aligned
This functional inspection helps confirm that the GMT mechanism operates correctly and is not simply a visual display.
QC Observations
The inspected ONE Factory Rolex GMT-Master II 126710 showed stable movement readings and balanced overall proportions.
The measured case diameter was 40.0 mm, the case thickness was 12.3 mm, and the individual watch weight was 145.3 g. These measurements provide useful reference points for identifying the configuration of the inspected watch.
The sapphire crystal, dial printing, hand alignment, GMT hand position, bezel rotation, bracelet construction and clasp operation should all be checked individually before shipment.
The 0-second daily rate and 0.0 ms beat error were particularly notable in this test. However, these results apply only to the testing position and conditions used during this inspection.
ONE Factory and the Former ARF Factory
ONE Factory is presented in the market as the continuation of the former ARF Factory, rather than a newly assembled production team.
According to the available factory and market information, the original team and production system continue under the ONE Factory name. This helps explain why some current ONE Factory models retain manufacturing characteristics associated with earlier ARF products, including bracelet construction, exterior finishing and overall assembly style.
Even so, the factory name alone should not be treated as proof of quality. Different production batches may still vary.
The most reliable way to evaluate a specific watch is to inspect:
* The actual 3285 movement performance
* Independent GMT hour-hand operation
* Date-change function
* Dial and hand alignment
* Bezel rotation and insert alignment
* Crystal clarity and date magnification
* Bracelet and clasp security
* Measured dimensions and weight
* Overall finishing and assembly
