Swiss-Grade Caliber 4131 Clone Movement
The Rolex Daytona 126506 super clone runs on a Swiss-grade automatic chronograph movement engineered to reproduce the genuine Rolex Caliber 4131 in feel, frequency, and autonomy. Caliber 4131 is the chronograph movement Rolex introduced with the 2023 Daytona update, and this clone follows its column-wheel chronograph layout. The movement operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a 72-hour power reserve.
Accuracy and Chronograph Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 4131. The central chronograph seconds hand starts, stops, and resets cleanly through the screw-down pushers, and the 30-minute and 12-hour counters track elapsed time accurately. The smooth sweeping seconds hand and the quiet winding rotor confirm the Swiss-grade build.
