This is a genuine Rolex original part – the 3186-260 minute wheel, a critical component in the motion work of the 3186 GMT movement. While retaining the same mounting dimensions as its predecessor (3185), the 3186 movement features a revolutionary redesign of its setting mechanism. By shifting the hour‑hand adjustment point from the hour wheel (as used in the 3185) to a special spring‑loaded coupling with the minute wheel, the 3186 eliminates the hand‑rocking/wobbling that occurred when setting the GMT/independent hour hand on the 3185.
This part is essential for the independent jumping‑hour GMT function and the hallmark “rock‑free” setting feel of the 3186 movement.
Genuine Rolex Part – Swiss factory‑original, designed specifically for the 3186 GMT movement.
Eliminates Hand Wobble – Spring‑loaded coupling on the minute wheel eliminates the play/rocking when setting the independent hour hand.
Core of Jumping GMT – Essential for the independent jumping‑hour GMT function.
Precision Engineered – Fine gear teeth and spring coupling ensure smooth, backlash‑free setting.
Essential for Service/Upgrade – For repairing a 3185 or upgrading it to 3186 feel, this minute wheel is required.

Replacing the 3185 minute wheel with 3186-260 to eliminate hand wobble when servicing
Replacement of worn or damaged minute wheel during movement service
Repair of GMT setting issues or loose hands caused by faulty minute wheel
1. Is this a genuine Rolex minute wheel?
Yes. It is a Swiss factory‑original part (3186-260) for Caliber 3186, not a copy.
2. What is the difference between 3186 and 3185 minute wheels?
The 3185 minute wheel is standard, causing slight hand wobble when setting the independent hour hand. The 3186-260 has a spring‑loaded coupling that eliminates wobble, providing a firmer, more precise setting feel. They are dimensionally interchangeable.
3. What are the symptoms of a faulty minute wheel?
Symptoms: slipping or jumping when setting time/GMT hand; hands not moving proportionally; loose or wobbling hands after setting; rough GMT jumping.
4. What should I pay attention to during installation?
The minute wheel sits above the center wheel. Ensure proper meshing with the intermediate wheel and hour wheel, and align the spring coupling. Follow the Rolex technical guide. Professional installation is strongly recommended.
5. Does this minute wheel fit Caliber 3185?
Yes. The 3186-260 can directly replace the original minute wheel in a 3185, upgrading the setting feel to the wobble‑free 3186 style. This is a common service upgrade.
