Seiko Spare Part – Winding Stem for Seikomatic Lady (Ladies' Automatic) (1 Piece) – NOS

Original Seiko Winding Stem from New Old Stock (NOS) for the Seikomatic Lady (セイコマチックレディ) – Seiko's ladies' automatic model from the 1960s. Offered is a single piece, taken from an original "FOR SEIKO" dealer bag (imprint "マチックレディ用" = "for the ...matic Lady").

The winding stem is a central component of the keyless works and is necessary for winding and setting the hands: The square end engages with the clutch/winding gear train, and the external thread accommodates the crown.

The Seikomatic Lady was an automatic ladies' model from the 1960s. Original, unused spare parts for these early Seiko movements are difficult to find today – relevant for watchmakers and collectors.

The part is unused and in very good original condition; due to storage, minor, purely optical traces may be present, which do not impair the function.

Note on assignment: Please compare dimensions and fit with the required winding stem before installation.
