Rolex Sky-Dweller 326939 Fluted Bezel Black Dial 42MM Mens Replica Watch

This black-faced Sky-Dweller with a triangular grooved bezel pushes precision reproduction to a new level. The bezel is engraved using German five-axis linkage CNC technology, and each groove is hand-mirrored three times to perfectly reproduce the unique reflection angle of the original platinum. The deep black dial uses Swiss electroplating technology, and it will present a gradient luster that is exactly the same as the original under different light. The exclusive caliber 9001 movement is equipped with a beryllium bronze alloy balance wheel, and the annual error is controlled within ±15 seconds. The rotation damping of the dual time zone function accurately restores the original factory's unique 3.6 Nm resistance value. The most amazing thing is the annual calendar module-using aviation-grade memory alloy springs, the instantaneous jump action on the last day of each month can perfectly reproduce the 0.58-second mechanical delay of the Geneva authentic. This is not an ordinary reproduction, but a mechanical art reinterpreted with modern engineering, and every detail can withstand the extreme test of professional instruments.
