FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genuine ETA 2671-2576 Date Jumper, 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 2671 automatic movement (8.25 lignes, widely used in ladies’ watches). The part number 2671-2576 is the specific date jumper for this movement. Common brand applications include: Omega Constellation (ladies), Longines La Grande Classique, Tissot Everytime, Certina DS, Hamilton Jazzmaster Lady, and many other ladies’ automatic watches using the ETA 2671 platform.

Q3: What does the date jumper do?
A: The date jumper is a spring-loaded lever in the date mechanism. At midnight, the date driving wheel pushes against the date jumper spring, which then releases and advances the date disc by one position. It controls the precise timing and force of the daily date change. A worn or broken date jumper causes: the date not advancing at all, advancing incompletely (stuck between two dates), or advancing too slowly.
