Swiss-Grade Caliber 4130 Clone Chronograph Movement
The Rolex Daytona 116528 super clone runs on a Swiss-grade automatic chronograph movement engineered to follow the genuine Rolex Caliber 4130 in feel, frequency, and autonomy. The movement operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a 72-hour power reserve for a full weekend off the wrist.
Chronograph Operation, Accuracy and Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 4130. The chronograph starts, stops, and resets through the two screw-down pushers, and the central seconds hand returns cleanly to zero on reset. The smooth sweeping seconds hand and the quiet winding rotor confirm the Swiss-grade build.
