Swiss-Grade Caliber 3055 Clone Movement
The Rolex Day-Date 18038 super clone runs on a Swiss-grade automatic movement engineered to reproduce the genuine Rolex Caliber 3055 in feel, frequency, and autonomy. The Caliber 3055 is the movement Rolex fitted to the 18038 from the late 1970s, and it introduced the quickset date that lets the wearer advance the date without turning the hands. The movement operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a 48-hour power reserve.
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 3055. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build. The instantaneous day jumps cleanly at midnight, and the quickset date advances on its own crown setting for fast date changes.
