Testing Note
The above measurements were recorded from this individual watch during its pre-shipment QC inspection.
Mechanical movement performance may vary depending on mainspring power reserve, watch position, wearing habits, ambient temperature and testing conditions. A single timegrapher reading represents the measured performance at the time of inspection and should not be interpreted as a fixed daily rate under all wearing conditions.
Movement
This watch is equipped with a Rolex Clone 2236 automatic movement, operating at 28,800 vibrations per hour.
During the QC inspection, the movement demonstrated stable performance with a measured result of -3 seconds/day, 270° amplitude and 0.1 ms beat error, indicating smooth and consistent operation during testing.
The movement supports automatic winding, manual winding, time-setting and date adjustment functions for everyday use.
QC Observations
The THB Factory Rolex Datejust 31mm stands out for its dial colour accuracy, which is one of the key strengths of this version when compared with other factories currently producing the same model.
During inspection, the overall appearance of the watch was excellent. The dial finish, colour tone and overall presentation delivered a refined visual effect, making this version particularly attractive for buyers who prioritize dial aesthetics.
One area that requires special attention is the bracelet clasp. Some versions from other manufacturers may have clasps that do not close securely. For this reason, the clasp locking mechanism on this watch received additional attention during the pre-shipment QC inspection to ensure that it closed firmly and operated correctly before shipment.
Considering the dial quality, overall finishing, movement performance and careful bracelet inspection, the THB Factory Datejust 31mm remains a highly recommended option in its category.
