Swiss-Grade Caliber 4131 Clone Movement
The Rolex Daytona 126518LN 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 new-generation Daytona movement Rolex introduced in 2023, and this clone matches its 28,800-vph beat rate and 72-hour power reserve for a full weekend off the wrist.
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 chronograph starts, stops, and resets cleanly through the two screw-down pushers, and the central seconds hand snaps back to zero on reset. The smooth sweeping motion and the quiet winding rotor confirm the Swiss-grade build.
