Testing Note
The measurements 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, wearing conditions, ambient temperature and testing conditions. For this reason, readings taken at different times or under different conditions may show minor variations.
Movement and Chronograph Function
This watch is equipped with a 3126 automatic chronograph movement. The chronograph hands, subdials and pushers are functional components rather than decorative elements.
During the QC inspection, the following chronograph functions were tested:
* Chronograph start
* Chronograph stop
* Chronograph hand operation
* Chronograph reset
* Subdial operation
The chronograph pushers operated correctly during testing, and the chronograph hand was able to start, stop and return to its reset position.
This confirms that the movement provides a genuinely usable mechanical chronograph function rather than a decorative chronograph-style display.
QC Observations
The overall finishing and assembly quality of this APF Factory Royal Oak Offshore Chronograph 44mm was good during inspection.
Compared with lower-priced versions available on the market, this version showed noticeable improvements in case finishing, dial details, strap construction and overall assembly. The connection between individual components appeared more refined, while the exterior finishing presented a more consistent overall appearance.
The softness of the strap was another notable feature during inspection. The strap offered good flexibility and was able to follow the shape of the wrist more naturally, helping improve wearing comfort while maintaining a secure fit.
The watch is also equipped with a functional 3126 automatic chronograph movement. Its start, stop and reset functions operated correctly during testing, and the chronograph display is not merely decorative.
For buyers who place importance on movement performance, functional chronograph operation, exterior finishing and wearing comfort, this APF Factory version is worth comparing and considering.
