Swiss-Grade Caliber 3186 Clone Movement
The Rolex GMT-Master II 116769TBR super clone runs on a Swiss-grade automatic GMT 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 a full day off the wrist. The caliber drives the independent 24-hour GMT hand and a quickset date.
GMT Operation and Accuracy
The local hour hand jumps in one-hour steps without stopping the seconds hand, so the wearer resets the time when crossing a time zone. The independent 24-hour GMT hand tracks home time for the second zone reading. Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer standard of the genuine Caliber 3186, and the smooth sweeping seconds hand confirms the Swiss-grade build of this 116769TBR Super Clone.
