ETA 2671-434 Movement Click

Product Description

The ETA 2671-434 Movement Click is a genuine Swiss-made component for the ETA 2671 automatic movement. The click is a critical locking component in the movement’s automatic winding system, working together with the ratchet wheel to securely lock the mainspring energy during non-winding phases and prevent reverse rotation. When the click is worn or damaged, automatic winding efficiency drops significantly or fails entirely. As an original factory part, it is the ideal choice for replacing worn components during service or repair.
