Swiss-Grade Caliber 3155 Clone Movement
The Rolex Day-Date 36 118235 super clone runs on a Swiss-grade automatic movement engineered to reproduce the genuine Rolex Caliber 3155 in feel, frequency, and autonomy. The Caliber 3155 is the movement Rolex used in the 118xxx-series Day-Date 36 before the modern Caliber 3255 arrived. 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 3155. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build. The day and date both advance at midnight through the Day-Date dual calendar mechanism.
