Swiss-Grade Caliber 1575 Clone Movement
The Rolex Explorer II 1655 super clone runs on a Swiss-grade automatic movement engineered to reproduce the genuine Rolex Caliber 1575 in feel, frequency, and autonomy. The Caliber 1575 is the automatic movement Rolex used in the original 1655 and added a fixed 24-hour function for day-and-night reading. The movement operates at 19,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a 42-hour power reserve.
Accuracy and Running Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 1575. The 19,800-vph frequency gives the period-correct sweep of the first-generation Explorer II rather than the faster beat of modern calibers. The smooth seconds hand and the quiet rotor confirm the Swiss-grade build of the 1655 super clone.
