Swiss-Grade Caliber 3186 Clone Movement
The Rolex GMT-Master II 116718LN super clone runs on a Swiss-grade automatic movement engineered to reproduce the genuine Rolex Caliber 3186 in feel, frequency, and autonomy. The movement operates at 28,800 vibrations per hour, winds bidirectionally through a free-rotating rotor, and holds a 48-hour power reserve for two days off the wrist. The caliber drives the independent 24-hour GMT hand and the quick-set date.
Accuracy and GMT Performance
Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 3186. The smooth sweeping seconds hand and the quiet rotor confirm the Swiss-grade build. The local hour hand jumps in one-hour steps for fast time-zone changes, and the GMT hand stays synced to the 24-hour bezel on the 116718LN super clone.
