Original Seiko NOS spare part for the rare Seiko Crown Special from the early 1960s. This component is the clutch lever pin (Japanese: 押し鳥ピンOshidori Pin ), a functionally critical element in the keyless mechanism : It transmits the movements of the crown to the clutch lever, thus enabling the switching between winding and hand setting .
The Oshidori pin is extremely difficult to obtain individually today, as the Crown Special series was only produced for a very short time. However, this part is indispensable for an authentic restoration .
