FAQ

Q1: Is this a genuine ETA part?
A: Yes — this is a genuine ETA 2671-9433 Stop Lever, 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 2671-9433 is the specific Stop Lever 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 Stop Lever do?
A: The Stop Lever (2671-9433) is a safety lever that stops the balance wheel when the crown is pulled out to the time-setting position. When you pull the crown out, the stop lever is activated and physically contacts the balance wheel, preventing it from oscillating. This is essential because: 1) while setting time, if the balance continues to run, the seconds hand may advance during setting, making precise time adjustment difficult; 2) more importantly, if the balance and gear train continue to run during setting, the setting mechanism could be damaged. The stop lever protects both the watch’s accuracy and the movement’s integrity.
