Swiss-Grade Caliber 2235 Clone Movement
The Rolex Datejust 178240 super clone runs on a Swiss-grade automatic movement engineered to match the genuine Rolex Caliber 2235 in feel, frequency, and autonomy. The Caliber 2235 is the midsize automatic movement Rolex fits to the 31mm Datejust, and this clone operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a power reserve of approximately 48 hours for two days off the wrist. The caliber drives the central hours, minutes, seconds, and the date at 3 o'clock.
Accuracy and Daily Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 2235. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build. The 100-meter water resistance and the screw-down Twinlock crown let the 178240 super clone hold its seal through daily wear, hand washing, and light water contact.
