ETA 2671-407 Sliding Pinion

Product Description

The ETA 2671-407 Sliding Pinion is a genuine Swiss-made component for the ETA 2671 automatic movement family. As part of the keyless works mechanism, the sliding pinion (also known as the clutch wheel) moves axially along the winding stem to engage with either the winding pinion for manual winding or the setting mechanism for time and date adjustment. This brand new original part is essential for watchmakers restoring proper crown function and reliable mode switching when the original sliding pinion becomes worn or damaged.
