Swiss-Grade Caliber 4130 Clone Movement
The Rolex Daytona 116520 super clone runs on a Swiss-grade automatic chronograph movement engineered to reproduce 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 three days off the wrist.
Chronograph Action, 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 pushers engage with a clean, defined click, and the central seconds hand starts, stops, and resets cleanly. The smooth sweeping seconds hand and the quiet winding rotor confirm the Swiss-grade build.
