Junghans / Starshock-Special Shock Protection Springs
Junghans / Starshock-Special Shock Protection Springs for the upper and lower pallet secure the balance staff of vintage movements reliably and replace aged or deformed original parts.
The springs hold the cap jewel and hole jewel precisely in position, ensure the correct functioning of the historical shock protection, and stabilize the rate values permanently. This makes them ideal for revisions of rare movements where a precise fit, authenticity, and long-term reliability are crucial.
