Vintage Silvana Swiss Manual Wind Watch Speidel 10K RGP Band Runs Briefly Repair

Vintage Silvana Swiss manual-wind wristwatch with a vintage Speidel expansion band.  The watch winds and will begin running, but it only runs briefly and then stops. The crown continues to turn/wind without reaching a firm stopping point. Because of this, the watch is being sold as-is for repair, restoration, or parts and is not guaranteed to keep time.
