Swiss-Grade Caliber 4131 Clone Movement
The Rolex Daytona 126519LN super clone runs on a Swiss-grade automatic chronograph movement engineered to reproduce the genuine Rolex Caliber 4131 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 Function and Accuracy
The chronograph starts, stops, and resets through the two screw-down pushers, and the central seconds hand and the two counters measure elapsed time precisely. Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 4131. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build.
