FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genuine ETA 7750-260 Minute Wheel, Made in Switzerland, brand new. It is an original factory part from ETA (Swatch Group), the world’s leading movement manufacturer. Not a generic or replica part.

Q2: How do I confirm this part fits my movement?
A: Confirm your movement is an ETA/Valjoux 7750 chronograph. The part number 7750-260 is the specific Minute Wheel for this movement. Common brand applications include: IWC Portugieser Chronograph, Omega Speedmaster (older 7750 variant), Tag Heuer Monaco, Breitling Navitimer, and many other chronographs using the Valjoux/ETA 7750 platform.

Q3: What does the Minute Wheel do?
A: The Minute Wheel (7750-260) is the final output gear in the time-setting transmission chain. It receives motion from the intermediate setting wheel and directly drives the cannon pinion, which in turn drives the minute hand. The time-setting gear train is: Crown → Setting lever → Intermediate setting wheel → Minute wheel → Cannon pinion → Minute hand. The minute wheel is the second-to-last gear before the cannon pinion — it is the final transmission element before the hands. Without a functioning minute wheel, the minute hand cannot advance and accurate timekeeping is impossible.
