FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genuine ETA 7750-2569 Double Corrector, 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 with a date and day calendar display. The part number 7750-2569 is the specific double corrector 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 double corrector do?
A: The double corrector is a corrector lever mechanism that enables quick adjustment of the date and day without cycling the hands. In the 7750, the corrector plungers on the case side press against the double corrector, which in turn advances the date and day discs. The “double” indicates it handles two calendar corrections — typically both date and day. Without a functioning corrector, you would need to cycle the hands through 24 hours just to advance the date — a major inconvenience.
