Swiss-Grade Caliber 3186 Clone Movement
The Rolex GMT-Master II 116719BLRO 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 independently adjustable 24-hour GMT hand and the quickset date.
Accuracy and Dual-Time 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 without stopping the seconds hand, which lets the 116719BLRO super clone change time zones cleanly while traveling.
